## Can a body have an acceleration with zero velocity?

Yes, an object can have zero velocity and still be accelerating simultaneously..

## What is the acceleration of the ball when it reaches its highest point?

At it’s highest point, acceleration is zero. Then it begins it accelerates downwards. Upon acceleration, the ball will increase exponentially up to 180 mph. -9.8 m/s/s; the ball must stop before it changes direction to fall back down so the velocity at the apex of the trip is 0 but a is always 9.81 m/s/s at all times.

## Can a body have positive velocity and negative acceleration?

Answer: Explanation: Yes, a body can have positive velocity and negative acceleration at the same time.

## Can a body have constant speed but varying velocity?

Can A Body Have A Constant Speed And Still Have A Varying Velocity? Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.

## Can an object in motion have an acceleration of zero?

Yes, it’s possible to have zero speed while accelerating, but only for an instant. … Acceleration is the rate at which an object’s speed and direction are changing with time, so whenever an object passes through zero speed as it reverses directions it has a non-zero acceleration but a speed of zero.

## At what time is the acceleration zero?

Definition of Acceleration is “Rate of change of Velocity per unit time” & definition of Velocity is “Rate of change of Distance per unit Time”. It means that , when acceleration is 0 then , velocity is constant. In short whatever may be the Velocity, if it remains constant then we say that acceleration is zero.

## Can a body have acceleration at rest?

Finding the acceleration Thus, even though the velocity of an object at rest must be zero, acceleration can clearly be non-zero for objects at rest. A particle that is thrown vertically upwards stops momentarily at the highest point of motion.

## Is acceleration negative when going down?

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

## Why acceleration is maximum when velocity is zero?

Acceleration is the rate of change of velocity. If you are accelerating,that means every second your velocity is changing. … So once you have reached your maximum velocity, that means your velocity can’t get any higher. So, your acceleration must be zero.

## What does it mean when acceleration is 0?

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. Motion graphs represent the variations in distance, velocity and acceleration with time.

## Does 0 velocity mean 0 acceleration?

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. If the velocity is constant however, the acceleration is zero (because the velocity isn’t changing over time).

## What is an example of zero acceleration?

No acceleration means no change in velocity. For example an apple thrown in space. It will not stop moving or move at a different velocity. 1.1K views.

## What is acceleration at constant speed?

The rate of change of the velocity of a particle with respect to time is called its acceleration. … If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration.

## Is acceleration zero at the highest point?

At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.

## Does the initial velocity affect acceleration?

3. Initial velocity is independent of the slope of the graph; that is, the acceleration. An object thrown downward still accelerates after release at the same rate as an object that is dropped.
