An object in motion (constant velocity) stays in motion, and an object at rest stays at rest, unless acted on by an unbalanced force. An object in motion (constant velocity) stays in motion, and an object at rest stays at rest, unless acted on by an unbalanced force.
In words, what is Newton’s 2 nd Law?
Force is equal to the product of the mass and acceleration
What are the 3 equations used in Newton’s 2 nd law?
F= M x A M = F/A A = F/M
What is Newton’s 1 st Law also called?
The Law of Inertia
Name three types of Friction?
Rolling Friction Sliding Friction Fluid Friction Static Friction
What are three forces a person rollerblading is experiencing?
Rolling Friction Fluid Friction Gravity Inertia
What is friction?
Friction is the force created when 2 surfaces rub together.
What direction does friction always go?
Friction is the force that is opposite to the direction of the movement of the object.
What is it called when two unequal forces are acting on the same object?
When an unbalanced force is applied to an object, the result is________?
Acceleration (or movement)
If two forces are acting in the same direction on the same object. (They are working together) How do you calculate the net force?
When in the same direction you add

When gravity and air resistance are in balance (they are equal), what happens to the velocity of a falling object?
The velocity remains constant.
What is force?
A push or a pull
When mass is increased, and acceleration remains constant, what happens to force?
Force also increases.
Given Force and Mass, what is the equation to find acceleration?
Acceleration = Force Mass
What is inertia?
The tendency of objects to resist a change in motion.
