**What happens to acceleration when velocity is constant?** At constant velocity acceleration is **equal to zero**.

**Does constant velocity mean acceleration is 0?** Acceleration means change in velocity over change in time. So as in this case constant acceleration means constant change of velocity w.r.t. time but zero acceleration means no change in velocity over time.

**What does constant velocity mean?** If a particle is moving with constant velocity, **it does not change direction**. If the particle is moving to the right, it has positive velocity, and if the particle is moving to the left, it has negative velocity.

**What does it mean to have a constant velocity?** An object has constant velocity **when both the magnitude and direction of the rate at which such an object is changing its position remain constant**. In other words, for an object to have constant velocity its movement has to not change directions over time and the object must have constant speed as well.

## What happens to acceleration when velocity is constant? – Additional Questions

### Does constant velocity mean zero velocity?

**No.** **Constant velocity means zero acceleration**, not the other way around.

### What moves at a constant velocity?

The constant velocity motion is a motion that has as a trajectory a straight line and a constant velocity. That a body is moving at a constant velocity means that there is no force or acceleration that is forcing him to move, this is why a body in a constant velocity motion the acceleration is null.

### What is constant velocity example?

**A car moving at a constant speed will elapse equal distance in an equal duration of time** hence is an example of constant velocity. The velocity of a car is measured as the ratio distance covered by the car from its initial position to reach a certain distance in time ‘t’.

### What is constant velocity on a graph?

A constant velocity means **the position graph has a constant slope (of 11.11 m/s)**. It’s a straight line sloping up, and starting below the origin. The displacement is the area under the curve of the velocity graph.

### Is constant velocity positive?

If the velocity is constant, then the slope is constant (i.e., a straight line). If the velocity is changing, then the slope is changing (i.e., a curved line). **If the velocity is positive, then the slope is positive** (i.e., moving upwards and to the right).

### How do you find acceleration with constant velocity?

Solving for Final Velocity from Acceleration and Time

**a = v − v 0 t ( constant a )** . a = v − v 0 t ( constant a ) . v = v 0 + a t ( constant a ) .

### What is the difference between constant velocity and constant acceleration?

When an object moves with a constant velocity, it means that the moving object has no acceleration. However, when an object moves with constant acceleration, its velocity changes by a constant amount throughout the same time interval.

### Does uniform acceleration mean constant velocity?

Translation: **If an object’s speed (velocity) is increasing at a constant rate then we say it has uniform acceleration**. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn’t have uniform acceleration.

### Is there acceleration in uniform motion?

Uniform motion is motion in which velocity is constant and **acceleration is 0**.

### Do uniform and constant acceleration the same?

In constant acceleration the body moving in a particular direction does not change its direction whereas in uniform acceleration the particle covers an equal distance in equal duration of time hence in both the situation acceleration of the body is zero.

### What happens to acceleration when velocity is zero?

This means that the change in the velocity is still taking place when the velocity of the object reaches zero. Therefore, **the body is still accelerating**. Example- When a ball is thrown upwards on earth with a constant velocity, the gravitational force of the earth acts on it in the opposite direction.
