Angela blows air into a balloon and holds the end of it closed with her fingers. When she lets go of the end of the balloon, Angela observes that the release of the air propels the balloon. The propelling of the balloon from the release of the air is an example of which of Newton’s laws?
a)
The force of an object is the product of its mass multiplied by its acceleration.
b)
A force of attraction exists between any two objects with mass.
c)
For every action, there is an equal and opposite reaction.
d)
An object in motion tends to stay in motion unless an unbalanced force acts upon it.

You are riding a bike down a hill and the front tire falls into a large hole, When the impact causes the bike to change motion....
a)
You will continue to move in the same direction and at the same speed as before the
impact
b)
the speed of the bike always increases, giving it greater force since the mass will remain the same.
c)
your speed will increase, since now you have, not one, but two forces acting on you
d)
the bike now has a
greater overall mass - its own mass plus the mass of the object by which it has
been struck
