## What is the acceleration of a motion with constant velocity?

If the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 5 m/s to 2 m/s over one second, its constant acceleration is −3 m/s2.

## Can you have constant velocity and acceleration?

Traveling with a constant velocity means you’re going at the same speed in the same direction continuously. If you have a constant velocity, this means you have zero acceleration. If you travel with a constant acceleration, your velocity is always changing, but it’s changing by a consistent amount each second.

**Does constant velocity mean no acceleration?**

If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a constant velocity is not accelerating.

### Does constant acceleration mean 0?

Constant acceleration means that the acceleration does not change. Some would say that if the acceleration is zero then the acceleration does not change and so one can say that the acceleration is constant.

### Does constant acceleration means constant velocity?

Sometimes an accelerating object will change its velocity by the same amount each second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.

**Does constant acceleration mean no acceleration?**

#### What is a motion map in physics?

Motion Maps A motion map can represent the position, velocity, and acceleration of an object at various clock readings. (At this stage of the class, you will be representing position and velocity only.)

#### How do you calculate acceleration with constant velocity and acceleration?

(3.5.8) v ¯ = v 0 + v 2. The equation v ¯ = v 0 + v 2 reflects the fact that when acceleration is constant, v is just the simple average of the initial and final velocities. Figure 3.5. 1 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate.

**Is acceleration constant at 40 km/h?**

In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate. The average velocity during the 1-h interval from 40 km/h to 80 km/h is 60 km/h: (3.5.9) v ¯ = v 0 + v 2 = 40 k m / h + 80 k m / h 2 = 60 k m / h. In part (b), acceleration is not constant.

## How do you find the average velocity of a moving object?

Lastly, for motion during which acceleration changes drastically, such as a car accelerating to top speed and then braking to a stop, motion can be considered in separate parts, each of which has its own constant acceleration. To get our first two equations, we start with the definition of average velocity: (3.5.5) v ¯ = Δ x Δ t.
