what the difference between constant and terminal velocity?
482160
In fluid dynamics, an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. ... At this point the object ceases to accelerate and continues falling at a constant speed called the terminal velocity (also called settling velocity).

Terminal velocity is achieved, therefore, when the speed of a moving object is no longer increasing or decreasing; the object's acceleration (or deceleration) is zero.

Explanation: UNIFORM VELOCITY: when an object is moving in a straight line, without any acceleration. ... CONSTANT VELOCITY: when the speed of an object has not changed even though the object may have experienced a change in direction (zero acceleration).

A free-falling object will initially speed up even in the presence of air resistance. ... Since the net force is equal to zero and the velocity is constant, the acceleration of a falling object which reached terminal velocity must be zero.

Yes, a body can have constant speed but variable velocity. For example, a body in uniform circular motion has constant speed but its velocity changes at every point during the course of motion. Whenever, the direction changes, velcoity changes.

Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.

A body is said to be in uniform motion when it covers equal distances within equal time intervals. So that means at constant speed. However constant velocity also seems to be correct.

'Uniform' and 'variable' are just terms we use to describe velocities. A uniform velocity stays constant over a period of time (unchanging), while a variable velocity is one such is that changes over time.

If a body is moving with constant velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion. Take the case of a freely falling body: it reaches its terminal velocity (120mph) when gravity = air resistance (drag).

Velocity is the displacement by an object per unit time. Acceleration is the change in velocity per unit time. So, a body in constant speed is said to have zero acceleration.

Acceleration is defined as the rate of change of velocity. constant velocity is the velocity which doesn't change per time. So,if the velocity is constant,the acceleration is zero.

The term constant acceleration means the acceleration is uniform that is it has a regular rate of change of velocity wrt time i.e. the incremental change in velocity is uniformly fixed wrt time; hence the reason why it appears a straight line on a velocity time graph. The motion is known as “uniform acceleration”.

constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.

As adjectives the difference between constant and perpetual is that constant is unchanged through time or space; permanent while perpetual is lasting forever, or for an indefinitely long time.

There are two ways to write this as a math formula: aav = Δv/Δt (The symbol Δ or "delta" just means "change.") aav = (vf - vi)/(tf - ti) In this equation, vf is the final velocity, and vi is the initial, or starting, velocity.

The voltage or the opposition force to a moving charge is proportional to its velocity(velocity of a charge is current or current density). In fact the relation between terminal velocity and Electric field itself is ohm's law put in a different way. You can look up for mathematical relation in Drift velocity.

Traveling with a constant velocity means you're going at the same speed in the same direction continuously. If you have a constant velocity, this means you have zero acceleration. ... If you travel with a constant acceleration, your velocity is always changing, but it's changing by a consistent amount each second.
