1.
Newtons Third Law.
a)
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
b)
Mida Sloan
c)
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
d)
For every action, there is an equal and opposite reaction
2.
When a heavy football player and a light one run into each other, who exerts more force?
a)
The heavy one
b)
The light one
c)
They are equal
d)
there is no such thing as force
3.
Newton's third law states that any action will have a(n) _______ and ______ reaction
a)
Equal and similar
b)
Equal and opposite
c)
Equal and different
d)
Greater and opposite
4.
A science book with a mass of 2.8 kg is pushed along a table with a net force of 1 N. What is the book's acceleration?
a)
0.28 m/s2
b)
0.32 m/s2
c)
0.36 m/s2
d)
0.38 m/s2
5.
A horse pulls forward on a carriage with a given force. By Newton's Third Law, the carriage must be pulling on the horse backward with an equal and opposite force. Given this, what explains why the horse and carriage can move forward?
a)
There is a brief moment where the horse pulls before the reaction force kicks in
b)
The forward force of the horse is just big enough to overcome the backward force of the cart and start the cart forward
c)
The cart is rolling on wheels while the horse's hooves have traction with the ground
d)
The forward and backward forces are equal, so it actually can't move forward
6.

a)
Contact Force
b)
Non-contact Force
c)
Balanced Force
d)
Unbalanced Force
7.
The sum of all forces acting on an object and direction
a)
Contact Force
b)
Balanced Force
c)
Unbalanced Force
d)
Net Force
8.
What is the net force in this diagram?
a)
8N right
b)
2 N right
c)
8N left
d)
2N left
9.

a)
True
b)
False
