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

What does a flat line on a velocity-time graph represent?

Back

Zero acceleration (constant velocity).

Front

If a drag racer accelerates from 0 m/s to 200 m/s in 5 seconds, what is the acceleration?

Back

40 m/s².

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²).

Front

If a car moves from 5 m/s to 35 m/s in 5 seconds, what is the acceleration?

Back

6 m/s².

Front

What does negative acceleration indicate?

Back

Negative acceleration indicates deceleration or a decrease in velocity.

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 constant acceleration?

Back

Constant acceleration means the rate of change of velocity is the same over time.
