Acceleration Practice Problems

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

If an object is at rest and starts moving, what is its initial velocity?

Back

The initial velocity of an object at rest is 0 m/s.

Front

What is the acceleration of an object that reaches a velocity of 27 m/s in 3 seconds from rest?

Back

The acceleration is 9 m/s².

Front

How do you interpret a negative acceleration value?

Back

A negative acceleration value indicates deceleration, meaning the object is slowing down.

Front

What is the formula for calculating deceleration?

Back

Deceleration can be calculated using the same formula as acceleration: a = (final velocity - initial velocity) / time, where the final velocity is less than the initial velocity.

Front

A horse increases its velocity from 0 to 15 m/s in 10 seconds. What is its acceleration?

Back

The acceleration is 1.5 m/s².

Front

What is the acceleration of a motorbike that comes to rest from 55 m/s in 5 seconds?

Back

The deceleration is -11 m/s².

Front

How do you find the change in velocity?

Back

The change in velocity is found by subtracting the initial velocity from the final velocity.
