Acceleration Practice

Front

What is acceleration?

Back

Acceleration is the change in velocity over time.

Front

How do you calculate acceleration?

Back

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

Front

If a sprinter accelerates from 5 m/s to 40 m/s in 10 seconds, what is the acceleration?

Back

3.5 m/s².

Front

If a sprinter starts from rest and reaches 40 m/s in 4 seconds, what is the acceleration?

Back

10 m/s².

Front

True or False: Acceleration only occurs when an object speeds up.

Back

False.

Front

What is the unit of acceleration in the metric system?

Back

Meters per second squared (m/s²).

Front

A truck starts from rest and gains a velocity of 20 km/hr in 8 seconds. What is the acceleration?

Back

2.5 km/hr/s.

Front

What does a negative acceleration indicate?

Back

It indicates that an object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
