Acceleration Practice

Front

What is acceleration?

Back

Acceleration is the change in velocity over time.

Front

What does it mean if an object is speeding up?

Back

It means the object's velocity is increasing.

Front

What does it mean if an object is slowing down?

Back

It means the object's velocity is decreasing.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at the same speed in a straight line.

Front

What does a graph with a horizontal line represent in terms of motion?

Back

A horizontal line represents zero acceleration (constant velocity).

Front

If a car accelerates from 20 m/s to 50 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (50 m/s - 20 m/s) / 5 s = 6 m/s².

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What happens to the acceleration of an object if the net force acting on it increases?

Back

The acceleration of the object increases.

Front

If a sprinter accelerates from rest to 40 m/s in 4 seconds, what is the magnitude of the acceleration?

Back

10 m/s².
