Physical Science: Semester 2 Test

Motion is described with respect to a

• graph

• displacement

• slope

• frame of reference

Displacement is distance combined with

• direction

• speed

• velocity

• magnitude

Displacement vectors of 3m and 5m in the same direction combine to make a displacement vector that is

• 2m

• 0m

• 8m

• 15m

Average speed is the total distance divided by the

• average distance

• average acceleration

• total time

• slope

The slope of a distance-time graph is equal to the

• speed

• acceleration

• displacement

• motion

Velocity is

• the slope of a linear graph

• acceleration divided by displacement

• speed with direction

• the same in all reference frames

Two or more velocities can be combined by

• graphing the slope

• using vector addition

• calculating the instantaneous speed

• determining the rate

A ball just dropped is an example of

• constant speed

• instantaneous speed

• combining displacements

• free fall

Acceleration is equal to

• distance divided by time

• change in speed divided by time

• the slope of a distance-time graph

• change in speed multiplied by time

The rate at which velocity is changing at a given instant is described by

• instantaneous acceleration

• average speed

• constant speed

• vector addition
