Q&A

Can a body have an acceleration when it is momentarily at rest?

Can a body have an acceleration when it is momentarily at rest?

Yes, a body have an acceleration when it is momentarily at rest. Hence, the ball experiences a acceleration although it is at rest.

When a body is at rest its acceleration is zero?

If a moving body comes to rest, then its acceleration is negative, as it’s velocity becomes zero. therefore the acceleration is also zero.

Can an object have zero acceleration and be at rest?

Yes, the body can have a non zero acceleration even when it is at rest.

What does it mean when the acceleration is zero?

According to the definition, the rate of increase of velocity is called acceleration. Theoretically, when a particle moves in constant velocity, there is no change in velocity with time. Then its acceleration is called zero acceleration.

Can an object have zero acceleration and nonzero velocity?

It is possible to have a non-zero value of acceleration when the velocity of a body is zero. At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2.

Can a body have zero velocity and still be accelerating?

Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction.

Is it possible to have acceleration when the velocity is zero?

Is zero acceleration constant acceleration?

NO. Because zero acceleration means no change of acceleration. That is no increase or decrease of acceleration throughout the path. In the other hand constant acceleration means constant increase or decrease of acceleration.

When a body moves with zero acceleration then the motion is called?

READ:   What courses should I take for film?

Answer: Uniform motion , covers equal distance in equal interval of time. there is no acceleration in uniform motion.

Can an object have zero acceleration and be in motion?

4) a) Can an object be moving when its acceleration is zero? Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.

How do you find zero acceleration?

When acceleration is zero (that is, a = dv/dt = 0), rate of change of velocity is zero. That is, acceleration is zero when the velocity of the object is constant.

How can acceleration be non-zero for an object at rest?

Thus, even though the velocity of an object at rest must be zero, acceleration can clearly be non-zero for objects at rest. Much more than the acceleration due to gravity \\(g\\). Much less than the acceleration due to gravity \\(g\\). Zero Almost equal to the acceleration due to gravity \\(g\\).

Why is the acceleration zero between 2-3 seconds?

Between the time intervals of 2-3 seconds, the velocity of the object is constant with respect to time; hence the body is experiencing zero acceleration as the slope of the v-t curve in this time interval is 0.

What are some examples of acceleration in physics?

Let us discuss 2 of the examples: 1. When you through a ball upside and when it reaches the top it pauses for a moment. At this moment, the velocity is zero but the ball still has acceleration and that acceleration is due to acceleration due to gravity. Thus at the peak, the velocity is zero but the object is still accelerating.

When an object is said to be accelerated?

An object is said to be accelerated if there is a change in its velocity. The change in the velocity of an object could be an increase or decrease in speed or a change in the direction of motion. A few examples of acceleration are the falling of an apple, the moon orbiting around the earth, or when a car is stopped at the traffic lights.
