Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

How is acceleration calculated?

Back

Acceleration (A) = Change in Velocity / Time.

Front

What units are used to measure acceleration?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

If a roller coaster accelerates from 6.0 m/s to 70 m/s in 4 seconds, what is the acceleration?

Back

16 m/s².

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating change in velocity?

Back

Change in Velocity = Final Velocity - Initial Velocity.

Front

What is the relationship between acceleration and time?

Back

Acceleration is the change in velocity over a specific time period.

Front

What is the term for a change in speed and/or direction?

Back

Velocity.
