Chapter 3 and 4 Physics Study Guide Review

Motion is described with respect to a:

• Graph

• Displacement

• Slope

• Frame of reference

It is necessary to choose a single reference point (frame of reference) when measuring motion because:

• it simplifies the description of motion.

• it allows for multiple interpretations of motion.

• it makes calculations more complex.

• it is not necessary to have a reference point.

What is the definition of 'Motion'?

• An object's change in position relative to a reference point

• An object's speed in a given direction

• The force exerted by an object

• The energy possessed by an object
