Motion Speed

A type of friction that occurs when an object slows down due to coming in contact with air molecules.

• Gravity

• Friction

• Air Resistance

• Force

The rate at which velocity changes over time. (Either in speed, direction or both.)

• Velocity

• Motion

• Speed

• Acceleration

a SCALAR quantity...

(Mark all that apply.)

• is distance

• is displacement

• is velocity

• has only one label

• has two labels

a change in position over time

• acceleration

• motion

• distance

• speed

• displacement

a VECTOR quantity...

(Mark all that apply.)

• is distance

• is displacement

• is velocity

• has only one label

• has two labels

In order to find DISTANCE...

• multiply time with speed

• divide time by speed

• divide speed by time

• add time and speed

Speed answers should be labeled...

• hr, min, s

• m, cm, km, mm

• m/min, km/hr, cm/s, m/hr

in order to find an average SPEED...

• multiply time with distance

• divide time by distance

• divide distance by time

• add time and distance

when speed remains the same at all times

(travelling the same distance in a unit of time)

• instantaneous speed

• constant speed

• changing speed

• normal speed
