what is the acceleration when the velocity is 0?

If the velocity was previously zero, and still is zero, then the acceleration is zero. If there was previously a non-zero velocity, but the velocity is now zero, then the acceleration is the change in velocity divided by the change in time.

what is the acceleration of a body moving with constant velocity? Acceleration is zero when the body is moving with a constant velocity.

At maximum height, the vertical component of the velocity is zero, leaving only the horizontal component. So the angle between velocity and acceleration is 90 degrees.

The velocity of a particle is zero at t=0. If the acceleratin is zero from t=0 to t=10 s, the speed is also zero in this interval. If the speed is zer4o from t=0 to t=10 s the acceleration is zero in this interval.

Answer and Explanation: The acceleration of a car that maintains a constant velocity of 100 km/h for 10s is zero. Acceleration is a change in velocity.

And it's not zero, it's -9.8m/s/s, as you acknowledge, so the direction of acceleration is meaningful. The no math answer to this one is to realize that acceleration is the rate of change of velocity. At the top most point, the velocity is indeed zero.

Acceleration is rate of change of speed, where the speed itself is changing per unit time. ... Now an object moving at constant speed has zero rate of change of speed obviously, and hence the acceleration is zero. An example is an object moving in space with constant speed.

If the velocity is constant however, the acceleration is zero (because the velocity isn't changing over time). Although at an instant in time it is possible to have zero velocity whilst accelerating. For example, if you drop an object at the instant you release it it has zero velocity but it is accelerating.

If the motion is circular then the angle between velocity vector and acceleration is 90°. If the motion is linear the angle may be 0° (if speed increases) or 180°(if speed decreases)

For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s2.

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.

For a projectile fired straight upwards , its velocity at max height = 0 whereas its acceleration at that instant is 'g' ( = 9.8 m/s² ) vertically downwards . So dot product of velocity and acceleration is zero at max hieght in this case .

The acceleration of a particle is directly proportional to the square of the time t. When t=0, the particle is at x=24m. Knowing that at t=6s, x=96m and v=18m/s, express x and v in terms of t. Need to see the solution to understand.

acceleration. the rate at which velocity changes is called. acceleration. in an acceleration graph showing speed versus time, a straight line shows the acceleration is. constant.

Then, explain your reasoning. At a projectile's highest point, its velocity is zero. At a projectile's highest point, its acceleration is zero.

Zero acceleration simply means there is no change in velocity with time and no change in velocity means neither its magnitude is changing nor the direction. Whereas constant acceleration say for example g=9.8m/s^2 shows the change in velocity with time (either its speed or direction).

When a velocity is changing as a result of a constant acceleration, the average velocity can be found by adding the initial and final velocities, and dividing by 2. The unit for velocity is meters per second (m/s). Note that this formula applies for constant acceleration only.
