How do animal keep balance when it is running?

Dinosaurs keep balance through the use of their tail. Additionally, think of it as how we ride a bike. The more speed, the easier it is to balance.

No. Animals have muscles. Plants do not.

Hi, I barrel raced for years and won alot.  The best thing I can say is to try to stay as close to the horse as you can for air streaming.  Good balance is a must.  I tied a barrel with a cable through it between two trees.  Then had someone shake it slowly at first, then faster as I got better.  It's a trick I learned from watching my brothers pratice bull riding.  It really does work.  Another thing is when you are practicing, at first anyway, make sure the horse you are riding already knows the barrels.  A green horse will fight and throw you all over the place.  Believe me I know!!!!!  When you sinch your saddle on, walk your horse, then sinch again.  3 times.  That should make sure your saddle is on tight enough.  Alot of horses will blow themselves up, so the saddle won't be very tight. When you walk them, they can't bloat themselves out.  Last but not least, even if you fall, KEEP GETTING BACK ON!!!! No matter how much it hurts.  Hope you have lots of fun, I did.

It's a non-moving animal.  It's cell type belongs to the animal kingdom.

The horse is transferring energy to the weight (i.e., doing work). Power is the rate at which the work is being done; power=energy/time. \n\nWhen the weight is released, potential is converted to kinetic energy. When the weight hits, the energy can go in a variety of ways:\n1) The noise of the impact carries away energy in the form of sound waves.  These quickly dissipate as heat.\n2) If something breaks, surface energy is created and dissipated as heat. You could consider this as the amount of work required to separate a solid object into pieces.\n3)If the floor flexes under the weight of the load, it stores energy  as a spring.\n4) Permanent deformations absorb energy as work done on the material and dissipate it as heat.\n5) there's probably more, but that should give you the general idea.

LOL.....cute question.....they have round butts with no legs.  You can't fall down if you have no legs.

They generally dont break on their own, but you do have to be very careful when handling them not to break either their legs or feet because they are so thin and they thrash around a lot when handled (in a zoo setting, please dont go around capturing flamingos). if they were prone to leg breaks, the species would not survive.

It walks on its feet. \n\nThat answer seems way to obvious. Am I missing something?

run in a zigzag fashion to escape them. Their spines are not flexible enough for them to take corners well enough to keep up. In a straight line however, for short distances, they can easily attain 35-40 mph!

I think all vertebrates use the same system we do.\n\nbugs have sensory hairs at all their joints. Especially the joints to head and to abdomen tend to be most important for gravity/balance perception (most mass attached). \nIn flying insects the ocelli (three single lens eyes on the top of their head) are thought to help with flight stabilization. Also flying insects have halteres to help with flight stabilization\n\nJellyfish, mussels and other marine invertebrates have statoliths/statocysts. Statoliths are made of a particular dense material and their displacement during acceleration/deceleration can be measured. \n\nI don't think bacteria care, but then they are not animals

Horses usually do not jump unless there is a need (a rider telling him, or something on the other side of the fence he wants).  In fact they usually attempt to run through fences, rather than jump over them.\n\nProperly trained and conditioned horses have the ability to jump great heights.\n\nHorses without riders are able to jump higher because of the reduced weight...however, you have to convince the horse that he wants to jump by himself.

It's not so much that a bat has to hang upside down, some bats, such as the famous vampire bat, are quite good at moving around on the ground using their feet and wings as locomotory limbs.\n\nMost bats have developed adaptations that allow them to hang upside down easily.  The tendons and ligaments in their feet are arranged in such a way that their natural position is 'flexed'.  It actually takes deliberate effort for them to let go with their feet.  So when they wrap their toes around a branch, or hook their claws on a crack or crevice in the rock, they can rest and even sleep without fear of falling off.  Their feet are locked in place.\n\nMost bats have their feet pretty much turned around, so that if they were lying down, the soles of their feet would point up.  This makes roosting and even catching flying prey easier, but makes walking somewhat ackward.  While they can do it if they really need to, they usually don't.  Sort of like a human crawling on their hands and knees.  We can do it, but it's not really what our limbs are adapted to do.

It locks legs in place so they can't move.

A bicycle is a wonderful example of an object that's unstable at rest, but stable in motion. My other favorite example is a broom balancing upside-down on the palm of your hand. Let's take a moment to look at the broom because it will help to understand the bicycle. \n\nWith the broom exactly centered above your motionless hand, nothing pushes it to one side and it balances. It's in equilibrium-it experiences no overall forces. In principle, it can stay that way indefinitely, but in practice it never does. The slightest shift of the broom's center of gravity to one side and over it goes. Any disturbance that shifts the broom away from equilibrium gives rise to forces that push the broom still farther from equilibrium, so the equilibrium is unstable. Any object that has no base of support-the polygon formed by its contact points with the ground-has an unstable equilibrium and tips over when disturbed. That instability stems from the fact that its center of gravity always descends when it's tipped and it releases gravitational potential energy as a result. Potential energy-energy stored in forces-is so intimately related to the forces themselves that whenever an object can release potential energy by heading in a certain direction, it naturally accelerates in that direction. \n\nSo the broom is unstable in your motionless hand. But if you move your hand, you can stabilize the broom. You do this by endlessly moving your hand under the broom's center of gravity. If the broom starts to tip to the left, you move its handle to the left to place that handle under the broom's shifted center of gravity. In that manner, you keep returning the broom to its equilibrium. Even though the equilibrium is naturally unstable, you keep helping it out and make it dynamically stable-stable in motion. \n\nNow let's shift to the bicycle. Like the broom, an upright but motionless bicycle is in an unstable equilibrium. If you're really skilled, you can balance it by shifting your weight around to keep the overall center of gravity above the wheels. However, there's a much easier way to balance the bicycle: drive forward! Once the bicycle is in forward motion, it steers automatically and places its wheels under the overall center of gravity. Unlike the broom example, where you have to think in order to push the handle under the center of gravity, the bicycle does this for you automatically. If the bicycle starts to fall over to the left, the front wheel steers left and the bicycle drives its wheels under the overall center of gravity. The bicycle returns to upright all by itself, even when you have no hands on the handlebars. \n\nThe automatic steering occurs for two reasons. First, there is gyroscopic precession that occurs when the spinning front wheel experiences torques from the ground. When the bicycle tips to the left, forces from the ground twist the spinning wheel so that its angular momentum shifts from leftward to rearward. This complicated precession effect causes the wheel to steer left toward the left. \n\nBut the more important source of automatic steering is that the tipped bicycle naturally flexes about its steering axis and turns its front wheel in the same direction as the tip. If you tip the bicycle left, the wheel pivots so as to steer the bicycle left. The fork and frame design are important to this effect. The tipped bicycle can reduce its gravitational potential energy by flexing and, as I mentioned above, this capacity to lower potential energy leads to forces that cause the tipped bicycle to flex. When you tip the bicycle to the left, it steers left and thus manages to reduce its gravitational potential energy-the bicycle's center of gravity descends slightly. Together with gyroscopic precession, this automatic steering makes the bicycle's wheels drive under the overall center of gravity so that the bicycle keeps returning to upright. So the forward-moving bicycle is like a broom w

Provides inertia in order to stabilize a trajectory.  If an object is still, it tends to stay still.  If moving, it tends to keep moving.  Helps to compensate for the effects of gravity.
