Laws of Motion Gravity/Force/Friction Which Law am I Which Law am I (pt.2) Calculations & Etc.
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.
Newtons First Law (Inertia)
The force that acts on all objects on Earth and is the only force acting on an object in free-fall is ___________.
Gravity
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 does “m/s” mean?
Meters per second
This is the natural tendency of objects to keep on doing what they're doing.
Newtons First Law (Inertia)
This is a push or pull.
Force.

Newton's 3rd law
What net force is acting on a 15 kg wagon that produces an acceleration of 3 m/s
45 N
F = M * A Force = Mass x Acceleration
Newtons Second Law of Motion
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
This is why the two parts of a force pair do not cancel each other
The forces are exerted on different objects
An object will _________________ in the direction that you push it.
Accelerate
What effect do unbalanced forces have on an object’s motion?
Unbalanced forces change an object’s motion.
A kickball continues to roll until it hits the fence.This is an example of which law of motion?
Newton's First Law

Newton's 3rd law
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?
25 N to the left
Newton's 3rd law states..
"For every action there is an equal and opposite reaction."
What type of force resists any object’s motion in the opposite direction?
Friction
