A force acts on a moving rubber ball.
How many of the following changes could happen to the ball because of the force?
• a change in direction
• a change in shape
• a change in mass
• a change in speed
A 1 B 2 C 3 D 4
the answer is C which is 3 but i didnt understand why??
3, because, A force CAN change the direction, shape, and speed, BUT a force CANNOT change the mass of an object.
Recall forces.
So...
Only 3/4 are correct, thus C.
