Can the velocity of an object be zero at the same instant its acceleration is not zero?

Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs. It is possible to have a non-zero value of acceleration when the velocity of a body is zero.

Can the velocity of an object be zero at the same instant?

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.

Can the velocity of an object be zero at the same time that that its acceleration is nonzero explain and give an example?

Yes. For example, a rock thrown straight up in the air has a constant, nonzero acceleration due to gravity for its entire flight. However, at the highest point it momentarily has a zero velocity. A car, at the moment it starts moving from rest, has zero velocity and nonzero acceleration.

When the velocity of an object is zero at an instant?

A : When the velocity of an object is zero at an instant, the acceleration need not be zero at that instant. R : In motion under gravity, the velocity of body is zero at the top – most point. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).

What happens when velocity is zero?

If velocity is 0 , that means the object is not moving, but with acceleration present, there is a force acting on the object. Velocity slows to a halt, but is subjected to an acceleration of 9.8 ms2 [down] .

What is zero velocity called?

Explanation: An object having zero velocity implies that it is stationary at a particular location. If we plot it on a velocity-time graph which represents velocity on the y -axis and time on the x -axis, it is represented by x -axis.

When velocity is 0 What is acceleration?

Here, accelerations deals with the rate of change in velocity, which means you need the change in velocity . In case, if the question means that if the velocity is always 0 then, the acceleration is always zero. But if the final velocity is zero then the acceleration is negative i.e deceleration.

What is acceleration when velocity is zero?

When acceleration is zero then velocity of object can be zero or constant. The body continues to move with its velocity throughout. For e.g if a train is at rest then acceleration is zero and velocity remains zero.

What happens when velocity is 0?

If velocity is 0 , that means the object is not moving, but with acceleration present, there is a force acting on the object.

What would happen if the acceleration of the ball was zero?

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. However, it is changing momentarily after that. If the acceleration was zero, the ball would have had no change in velocity and would have stayed up in the air forever.

What happens if the velocity is zero at an instant?

Originally Answered: If the velocity is zero at an instant, the acceleration should also be zero at that instant. Is it true? Give reasons? No this is not true. Acceleration is defined as rate of change of velocity at any instant.

What is the acceleration of a ball thrown upward by gravity?

Well Gravity is acting on the ball and holding it onto the ground. But it’s velocity with respect to the ground is zero and it is not changing. since its velocity is zero, its change in velocity is also zero and therefore its acceleration is zero. A ball being thrown upward which is decelerated by gravity stops its apex.

What is the initial velocity if acceleration is 0?

However, a 0 acceleration doesn’t say what the initial velocity is. The initial velocity could be 0, which means that the object was standing still. Or the initial velocity could be anything besides 0 which means that it was moving.
