7th grade Force and Motion Test review

Front

What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is the difference between speed and velocity?

Back

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

Front

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

Back

A flat line indicates that the object is not moving (stopped).

Front

What does a straight diagonal line on a distance-time graph indicate?

Back

A straight diagonal line indicates constant speed.

Front

What does a curved line on a distance-time graph represent?

Back

A curved line indicates acceleration or deceleration.

Front

If a car travels 100 km in 2 hours, what is its average speed?

Back

50 km/h.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What is the unit of acceleration?

Back

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