constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.

If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)

if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.

Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.

As an example, a car moving at 20 mph per hour in a circular path does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration.

If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.

There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.

Yes, a car accelerates in circular motion because although its speed may remain constant, its direction is constantly changing as it moves around the circle. This change in direction is considered acceleration.

constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
