Can an object have zero instantaneous velocity and non zero acceleration?

Can an object have zero instantaneous velocity and non zero acceleration?

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.

What does it mean when instantaneous velocity is 0?

The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t: The slope of the position graph is zero at this point, and thus the instantaneous velocity is zero.

Can a body have a velocity without acceleration give examples?

“Yes” a body can have zero velocity and can still accelerate simultaneously. So, at the highest point for a body thrown upwards, velocity is zero and acceleration is equal to g (9.8 ms^-2) in downward direction.

Can a body have a velocity without acceleration can it have an acceleration with zero velocity give examples?

Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity. Hope it helps!!

Can a body have zero velocity and finite acceleration justify?

In the simple harmonic motion during the motion, at the extreme positions, the velocity of the body is zero but the acceleration is highest. Therefore, a body can have zero velocity and finite acceleration.

Is the velocity of an object zero if it is accelerating?

No. For the most part velocity is not zero if an object is accelerating. Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. In other words, if something is accelerating, it has to have a variable velocity.

How can an object’s instantaneous speed be zero and it’s?

So this is an example of how there can be a non-zero acceleration (of − 9.81 m s − 2) but there can be a moment when the ball’s instantaneous velocity is zero. Small addition to John Rennie answer. In fact, if you hold a ball in your hand and will release it, then the ball starts its motion with non zero acceleration but zero speed.

Which is an example of acceleration of an object?

An example of this is a car with its brakes on. An object may be at rest (zero velocity) and have positive acceleration (such as a car just starting from rest; it is the acceleration on the car that causes a change in velocity.) There are other examples that we will discuss in future lessons.

Which is an example of a negative acceleration?

An object may be moving in a forward direction (+ velocity) and have negative acceleration. An example of this is a car with its brakes on. An object may be at rest (zero velocity) and have positive acceleration (such as a car just starting from rest; it is the acceleration on the car that causes a change in velocity.)
