FALSE
speed up, slow down, AND change in direction.
32mph west is velocity, explain WHY
speed AND direction (west)

How would you make this a balanced force?
Add 7N to the right
or
Subtract 7N from the left
Someone else or something else! being APPLIED to it
The combination of forces is called Net force
True
5 minutes is speed, explain WHY
only the amount of time NOT direction
