Laws of Motion Gravity/Force/Friction Which Law am I Which Law am I (pt.2) Calculations & Etc.
Newtons First Law (Inertia)
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.
Gravity.
The force that acts on all objects on Earth and is the only force acting on an object in free-fall is ___________.
Newton's 3rd law
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 2nd law
A car is easier to push than a bus. This is an example of which of Newton's Laws?
Meters per second
What does “m/s” mean?
Newtons First Law (Inertia)
This is the natural tendency of objects to keep on doing what they're doing.
Force.
This is a push or pull.
Newton's First Law
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 3rd law
The slingshot was pulled back and the rock propelled forward. This is an example of which law of motion?
45 N
What net force is acting on a 15 kg wagon that produces an acceleration of 3 m/s
Newtons Second Law of Motion
F = M * A Force = Mass x Acceleration
Running to School (not exerting a force)
Which of the following is NOT an example of exerting a force on an object: pushing a button, punching a mascot, running to school?
Newton's First Law
You left your book on table in Ms. Przelomski's room and it is still there the next morning. This is an example of which law of motion?
Newton's First Law
The Dominos flew out of the back of the truck when it crashed into the books. This is an example of which law of motion?
The forces are exerted on different objects
This is why the two parts of a force pair do not cancel each other
Accelerate
An object will _________________ in the direction that you push it.
Unbalanced forces change an object’s motion.
What effect do unbalanced forces have on an object’s motion?
Newtons First Law
A kickball continues to roll until it hits the fence.This is an example of which law of motion?
Newton's 3rd 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?
25 N to the left
Two people exert push on a box with forces of 50 N to the right and 75 N to the left. What is the strength and direction of the net force?
"For every action there is an equal and opposite reaction."
Newton's 3rd law states..
Friction
What type of force resists any object’s motion in the opposite direction?
Newton's Second Law
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 of Motion.
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?
Mass
