speed up
slow down
For the Orange boat, a force caused what type of change in velocity?
start moving
stop moving
change direction
speed up
slow down
Which boat had the greatest change in speed?
Both boats have the same change in speed
Blue Boat
Orange Boat
A _______ force can cause a greater change in velocity.
weaker
stronger
Which boat had the highest change in speed?
Blue
Orange
Grey
All boats have the same change in speed.
Which boat had the highest force exerted on it?
Blue
Orange
Grey
All boats have the same change in velocity so the force is the same on all 3 boats.
