Speed, Velocity, and Acceleration Review

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

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 the SI unit for speed?

Back

The SI unit for speed is meters per second (m/s).

Front

If an object comes to a stop, what is its final velocity?

Back

0 m/s.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

If a car travels 100 m in 5 seconds, what is its average speed?

Back

20 m/s.

Front

What is the formula for acceleration?

Back

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

Front

What is the SI unit for acceleration?

Back

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