What is the acceleration on Earth?
364646
Acceleration due to gravity on the Earth is 9.81 m/s^2 or 32.2 ft/s^2.\n\nUnless you mean the acceleration of the Earth?  If you assume a circular path (not true, but I'm guessing you're not doing rocket science, so I won't worry too much), acceleration on the earth by the sun would be the square of the velocity at which the eart travels divided by the distance from the earth to the sun. a = V^2/R.

Gravity is also like another force. it follows Newton's 3rd law. Earth attracts us and we attract Earth.\n\nBut a = f/m. Since our mass is less, we move with greater acceleration. For earth, mass is huge and the effect is negligible.

Gravity is proportional to the mass of the planet.  I'd say the acceleration on this planet is 0.1045 * 9.81 m/s^2.  \n\nFor b) use x =  1/2at^2\n\nt = time  \na = acceleration due to local gravity

Fnet= MA so you acceleration is 36km/h, so convert that to m/s, which is 10 m/s. To get acceleration, we know that the car started out at 18km/s, which is 5m/s. So the acceleartion = Change of velocity/Change of time. So that comes out 1 m/s/s. So there is 1000 Newtons on the car. The other guy's answer is wrong. I'm an engineering major. The standard Units in science is MKS, meters kilograms and seconds

approx 19 miles/second.\n\nAny force from centripetal acceleration you might feel would be more than compensated by the gravitational attractions from the Sun and Earth themselves.\n\nIt might be a measureable amount, but just barely.

acceleration = v^2/r or v*v/r (this is m/s^2 so divide by 9.81 to get g's)\n\nwhere v is the velocity\n\nr is the radius\n\nBe careful, think about the one g the pilot feels from the pull of the earth. ;)

You need to consider vectors ....\n\nAcceleration has a direction. In the case of gravity its down towards the ground. \n\nNow what accelerationis doing is changing the instantaneous velocity of the particle or object or whatever.\n\nVelocity is also a vector.\n\nSo if the velocity is in the opposite direction to the acceleration then the object will motion will slow down and eventually increase in the same direction as the acceleration.\n\nIf the velocity is in the same direction then it will increase in that direction.\n\n So if UP is defined as positive then down is defined as negative. This goes for:\n- position (above (+) and below (-) ground if ground level is defined as zero);\n- velocity is positive if the object is moving up and negaitve oif it is moving downward; and\n- acceleration is positive if applied upward or negative if applied downward.\n\nNote acceleration is in the same direction as an applied force as by Newton's Second Law, F = ma and mass is a scalar quantity .. it has no directionality. It is the same wherever the object is. (Not to be confused with weight which is a force attracting us to the ground and is dependent on the strength of gravity. So for example we weigh on earth and are weightless in space and are 1/6 of our weight on the moon etc ... In all locations our mass is the same but the forces acting on us are different)

We won't feel it because we are moving along with it. We will only notice any movement if the acceleration changes. It's like being in a car, when you speed up, you kind of stay in place for a moment and go back in your seat. If you stop suddenly, you go forward in your seat. If the Earth slows down, we will continue to move at the previous rate of speed and we will shoot through the atmosphere and land back on Earth many miles east of our original location.

The Earth and our body exert forces on each other according to Newton's law of gravity.  Essentially mass attracts other mass.

About the same as the escape velocity for earth. (9.47^2/95.2)^0.5 = 0.97\n\nBest of Luck - Mike

You may be confusing acceleration with velocity. An object in motion will remain in that motion unless a non-zero net force is applied to it. If you are in the void of space, and are traveling along at a particular velocity, you will remain at that velocity. On Earth, drag and other forms of friction will slow you down.\n\nAcceleration is different. For something to continue to accelerate, a constant non-zero net force must be applied to it.\n\nacceleration = force/mass so if I have a mass of 50kg and want to accelerate at 100m/s^2 (100 meters per second per second) then I need a constant force of 5000 newtons applied to me. Keep in mind that that is 5000 newtons relative to ME.\n\nNow, according to our current understanding of light, it would take an infinite amount of energy to reach speed of light because force = mass/acceleration and as you accelerate, your mass increases! Neither you nor I will notice this effect in our daily life but it becomes more noticable as you approach the speed of light. This does not create mass in the sense that new mass is appearing in the universe, it just adds more weight (no pun intended) to the mass that's already there. This is actully called the reletivistic mass. Your mass when you're at rest, is your rest mass.\n\nThough we won't be traveling close to the speed of light any time soon, there have been plans to get humans to high speeds without killing them. One such way is to accelerate in intervals. For example, you feel a strong force when taking off in an airplane but once the airplane reaches a few hundred miles per hour, and you've caught up, you can do it again.

Let's just talk about Earth. The earth's diameter is 12756 km. Its circumference is pi x 12756 = 40074 km. The earth spins 1 round in 24 hours. That's 1700 km/h, or 472 m/s. If it rotates in an OPPOSITE direction, it's like the Earth is rotating at 944 km/s and suddenly stops. What happens? You fly through the air at 944 km/s. All the houses fly through the air at 944 km/s. Whole forests fly at 944 km/s. Even whole mountain ranges and mountain tips fly at 944 km/s. The ocean's waters fly backward at 944 km/s. Talk about a uber tsunami. I don't know what the friction of air against these object would do to them. Can anyone solve that? Even the Earth's crust might become detached with its outer mantle, I think. Lava breaks out everywhere, global earthquakes... In short: All hell breaks loose. Man, that's even worse than the Death Star. Superman actually does that to Earth in one of his movies. He's a major nut!

Earth's speed changes from time to time.  The average is 29.783 kilometers/second or 107,218 kilometers/hour.

Force=Mass x Acceleration\n\nSo Acceleration = Force/Mass\n\nHope this helps

The Earth spins from west to east at about 900 mph. Looking from above the Earth's North Pole, the Earth rotates counter-clockwise around the Sun.

Let's try to anser the question without looking it up and without using a calculator.\n\nWe know Newton's gravitation law: F = G*m*M/r^2\nAnd we know the gravity on earth: F = m*g\n==> m*g = G*m*M/r^2\n==> M = r^2*g/G\nNow, the acceleration on the earth surface is approximately 10 m/s^2\nThe earth's radius is approximately 6*10^6 m\nAnd I remember G to be approximately 7*10^-11 Nm^2/kg^2\n\nM = 6^2*10/7 * 10^12/10^-11 kg\n\nThe earth weights about 5*10^24 kg\n\nIf you look it up in Wikipedia, it says 5,9736*10^24 kg. \n\nSo we're close enough if you take into account that we used rough estimates for the constants.

If we assume the Earth is a perfect spehere, the gravitational accleration would, indeed, be equal at any point along the surface of the sphere.\nWhen you take the rotation of the Earth into account, yes, at the equator, an object's "weight" is less than it would be at the poles.\n\nThe gravitational acceleration acts as the centripetal acceleration which keeps us all on on the Earth instead of flying out into space in a straight line.\nAt the poles, no centripetal acceleration is needed (neglecting Earth's revolution around the sun), but at the equation, the objects inertia acts to lessen the appearent effects of gravity and reduce its weight.  This is NOT due to the fictitious centrifuga force.
