Laws of Motion P1
An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton's First Law of Motion
Newton created ________ (how many?) laws of motion.
What is 3 laws of motion.
You run into your friend while skating and both of you fall in opposite directions. This is an example of which law of motion?
Newton's 3rd law.
A car is easier to push than a bus. This is an example of which of Newton's Laws?
Newton's 2nd law.
What is the amount of matter in an object? (how much stuff there is)
Mass
This is the type of force that opposes gravity when the object is at rest on a surface. It is always perpendicular to the contact surface.
Normal Force
You are thrown off the front of a 4 wheeler when it runs into a fence. This is an example of which law of motion?
Newton's First Law
The slingshot was pulled back and the rock propelled forward. This is an example of which law of motion?
Newton's 3rd law.
What is the distance traveled per unit of time?
Speed
F = M * A Force = Mass x Acceleration
Newton's Second Law of Motion
This is a push or pull.
Force.
You left your book on a desk in Mrs. Buckalew's room and it is still there the next morning. This is an example of which law of motion?
Newton's First Law
The dominoes flew out of the back of the truck when it crashed into the books. This is an example of which law of motion?
Newton's First Law.
This terms describes the force of attraction that exists between two masses.
gravity
This term describes the vertical, downward force exerted on a mass as a result of gravity.
Weight
A kickball continues to roll until it hits the fence. This is an example of which law of motion?
Newton's First Law
You let the air out of a balloon- the air goes one way and the balloon goes the opposite direction. This is an example of which law of motion?
Newton's 3rd law
What is the speed of an object in a specific direction?
Velocity
What are the Three Laws of Motion?
Inertia, Acceleration and Interaction
The reason a chair slows down after you push it across the floor is due to this type of force.
Frictional force/friction
A baseball hit with a wooden bat goes farther than a baseball hit with a plastic bat. This is an example of which law of motion?
Newton's Second Law
The baseball went farther than the basketball when your classmate hit them with an aluminum bat. This is an example of which law of motion?
Newton's Second Law of Motion
What is Newton's First Law of Motion?
This states that an object in motion remains in motion unless an unbalanced force acts upon it.
