Question #1: A basketball momentarily changes shape as it bounces off the floor. This is due to balanced forces acting on the ball.

Question

a. true
b. false

According to what I have studied when balanced forces are on an object, that object doesn't move, but when unbalanced objects act on an object, it will cause it to move and change shape. So I think the answer is "b".

Question #2: A ball slowing down as it rolls across a carpet is an example of

a. balanced force
b. friction
c. inertia
d. zero net force

According to what I have studied "a" and "d" are incorrect. I think the answer is "b" because friction causes things to slow down.

Question #2: If the net force acting on a wooden object is 0 N, the shape of the object

a. will not change
b. changes permanently
c. changes temporarily
d. reacts to unbalanced forces

According to what I have studied the answer would be "a" since no force is acting on the object. And for that reason the object will not change or move

I don't know if I'm right.
