Total questions: 20
Worksheet time: 38mins
Acceleration is
the rate at which velocity changes.
the change in velocity
the rate of change
when you speed up only
Velocity has two components
(pick 2 below)
direction
change in speed
speed up
slow down
In science, acceleration refers to
increasing speed
decreasing speed
changing direction
increasing speed only
What does it mean when a change in velocity is negative?
The object is speeding up.
The object is slowing down.
The object is changing direction.
The object is falling down.
If velocity is measured in meters/second and time is measured in seconds, the unit of acceleration is (pick 2 choices)
m/s/s
m/s2
m/s
m
