Physical Science - UNIT 6 Motion, Forces, Work, and Energy

SPEED IS CALCULATED BY…..

• DISTANCE/TIME (Distance divided by Time)

• TIME/DISTANCE (Time divided by Distance)

• MASS/VOLUME (Mass divided by Volume)

• VOLUME/MASS (Volume divided by Mass)

Answer explanation

SPEED IS ALWAYS CALCULATED BY DISTANCE/TIME. Meters per second (m/s) is the universal unit for SPEED AND VELOCITY..

What is the DEFINITION for FRAME OF REFERENCE?

• Used to describe the motion of an object relative to reference points (other objects that stay in place)

• Total movement of an object without any regard in direction

• The change in position in an object

• The speed of an object in a particular direction

Answer explanation

The second opinion is the definition for DISTANCE. The third option is the definition for DISPLACEMENT. The fourth option is the definition for VELOCITY.

In order to calculate SPEED, you must know…
