PS Chapter 11 Review

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 position-time graph is equal to the

• velocity

• displacement

• acceleration

• 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 velocity

• determining the rate

Jamie jogs each morning before work. She starts at 7:00 am and jogs 1 mile to the park and 1 mile back to her apartment. It takes her 24 minutes to complete her workout. What is her displacement during each of her morning jogs?

• 2 miles

• 24 minutes

• 0 miles

• 12 min / mile

Movement in relation to a frame of reference is called

• instantaneous speed

• average speed

• relative motion

• displacement
