Newton's 4th Law of Motion
3
What is known as a Push or Pull?
Gravity
Force
2nd Law of Motion
Friction
4
What does Newton's second law explain?
Why the speed of the ride changes
Why roller coasters do not have brakes
Why roller coasters have seat belts
Why roller coasters start with a big hill
5
When unbalanced forces act on a moving object, the velocity of the object will change. True or False?
False
True
6
What is another name for the 1st Law of Motion?
The Law of Inertia
The Law of Propulsion
The Law of Motion
The Law of Movement
7
What is your g-force as you sit here taking this test?
1 g since that is equal to the force of gravity
0 g's since I am not moving
I don't know how much I weigh and cannot calcualate g's because weight.
2 g's since I am sitting and not standing
8
What is the amount of matter in an object or a measure or the inertia of an object?
Weight
Mass
Newton's 1st Law of Motion
Acceleration
9
What is a free body diagram used for?
It is a picture that represents the velocity and speed acting on an object.
It is a sketch of a human body showing how gravity works.
A diagram that shows the forces acting on a human.
A picture that represents the object and the forces acting on the object
10
Who was the scientist that gave us the laws of motion?
Neil Armstrong
Isaac Newton
Albert Einstein
Charles Darwin
11
Forces occur in pairs. These pairs are sometimes called;
Agent and Receiver
Up and Down
Give and Take
Push and Pull
12
Acceleration is produced when a force acts on a mass. The greater the mass the greater the force needed.
Acceleration
Propulsion
Newton's 2nd Law
Newton's 1st law
13
What is Newton's first law of motion?
Force is relative to the motion of an object under a controlled environment
An object in motion will continue in the same direction until gravity acts
An object at rest remains at rest, or if in motion, remains in motion
An object will accelerate at a constant velocity
14
What do you call a force that opposes motion between two surfaces?
Velocity
Friction
Force
Inertia
15
Loop-de-loops are shaped more like teardrops than circles. What is this shape called?
Inversion loop
Olympia loop
Clothoid loop
Boomerang loop
16
A rock with a mass of 5.0 kg accelerates 8.0 m/s2 when a shovel applies force to it. What's the amount of the force?F=MA
40N
80N
1.6N
5/8N
17
A newton is a unit of force. How is a newton measured?
A newton equals 2.2 pounds.
It's the amount of force acting on a 1kg object producing acceleration.
The amount of gravity pulling on a 1kg object as it falls to Earth
A newton is equal to the amount of gravity acting on it.
18

C. Black Out
A. Grey-Out
All of the symptoms described above may occur
B. Tunnel Vision
21
The Law of Universal Gravitation basically states that;
Object on the moon fall faster than they do on Earth
The Earth's gravity pulls all other planets towards it.
Objects in the universe attracts other objects based on their mass
The force of gravity keeps all of the planets in orbit around Earth.
22
The "Father of Physics" is also credited with the following discovery;
The fact that the Earth revolves around the moon.
The formula for speed of sound.
The third law of thermodynamics
The Law of Conservation of Energy.
23

Anticipation
Potential and Kinetic are both at their highest
Potential
Kinetic
24
What is the known as the; result of unbalanced forces?
Mass
Force

25
What is inertia?
The tendency of an object to destroy anything that come's in it's path.
The tendency of an object to gain inertia in regards to Newton's 1st Law.
The tendency of an object to accelerate in regards to the force on it.
The tendency of an object to resist any change in its motion.
