Answers
1
When is physics applied?
Only things in motion
Everything
2
What is Newton's second law?
Acceleration = (force)(mass)
Acceleration is produced when a force acts upon a mass
Every action has an equal and opposite reaction
An object moving will move unless it is stopped
3
Where is physics?
Nowhere
Everywhere
4
What are force diagrams applied to
Every object that has mass
Everything!
Physics
All of the above
5
Which law of motion proves that if a baseball is thrown into space it will go on forever?
Third Law
First Law
Second Law
All of the above
6
Why do we have physics?
for knowledge
To hold the earth together
7
Do all these laws apply to motion?
Yes
No
8
When a Goliath beetle hits the windshield of a truck do they have the same force?
Yes, they have different amounts of force
No, they have the same amount of force
No, they have different amounts of force
Yes, they have the same amount of force
9
When do scientists use physics?
All the time
Never
10
Do newton's laws of motion apply to every day things that are in motion?
No
Yes
11
Why do we even use the laws of motion?
To understand motion and force better
To be smart and intelligent about everything
12
what is Newton's third law?
Every action has an equal and opposite reaction
Even action has an equal and opposite reaction
Every object has an equal and opposite reaction
Every movement has an equal and opposite movement

Second Law
Third Law
None of the above
First Law
14
What happens when a truck going 50 mph hits a concrete wall one foot thick?
It bounces off the wall
The truck goes through the wall
question 1 and question 3
the truck hits the wall, and the wall hits the truck back
15
what is a force diagram?
It's a diagram showing all the forces acting on an object
All of the above
It's a Diagram showing one particular force
It's a diagram representing the laws of motion
16
What is Newton's First Law?
Law of Inertia
An object resting will keep resting until it is moved
every action has an equal and opposite reaction
acceleration = (Force)(Mass)
17
