What is a reference point in motion?

Back

A starting point you choose to describe the location (or position) of an object.

Front

Define motion in terms of position and time.

Back

Change of position over time, an object's distance and direction from a reference point.

Front

How do you calculate the speed of an object?

Back

Speed is calculated by dividing the distance traveled by the time taken.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s) or meters per minute (m/min).

Front

If Camden's house is 4200 m from the baseball park and it took him 30 minutes to get there, what was his speed?

Back

140 m/min

Front

What does a speed of 0 m/s indicate about an object's motion?

Back

The object is at rest and not changing its position.

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 significance of a reference point in understanding motion?

Back

It helps to determine the position of an object relative to another object.
