The Nature of Force
Know your Law
Friction
Gravity
Momentum and Orbit
100
When one object pushes or pulls on another object.
What is Force?
100
An object at rest will remain at rest, and an object at constant speed will continue moving at constant speed unless acted upon by unbalanced force.
What is Newtons First Law of Motion?
100
The force that one surface exerts on another when the two rub against each other.
What is Friction?
100
The force that pulls objects with mass together.
What is Gravity?
100
The amount of matter in an object.
What is Mass?
200
The overall force on an object after all the forces are added together.
What is Net Force?
200
The net force on an object is equal to the product of its acceleration and its mass.
What is Newtons Second Law of Motion?
200
Friction that occurs when solid surfaces slide over each other.
What is Sliding Friction?
200
When the only force acting on a falling object is gravity.
What is Free Fall?
200
The product of an object's mass and velocity.
What is Momentum?
300
Can cause an object to start moving, stop moving, or change direction.
What is Unbalanced Force?
300
If one object exerts a force on another object, then the second exerts a force of equal strength in the opposite direction of the first.
What is Newtons third Law of Motion?
300
Friction that occurs when an object rolls over a surface.
What is Rolling Friction?
300
An object that is thrown.
What is a projectile?
300
An object that travels around another object in space.
What is a Satellite?
400
Equal forces acting on one object in opposite directions.
What is Balanced Force?
400
The total momentum of objects that interact does not change.
What is the Law of Conservation of Momentum?
400
Friction that occurs when an object moves through a fluid.
What is Fluid Friction?
400
A measure of the force of gravity on an object.
What is weight?
400
Any force that causes an object to move in a circle.
What is Centripetal Force?
500
The tendency of an object to resist change in its motion.
What is Inertia?
500
The force of gravity acts between all objects in the universe.
What is the Law of Universal Gravitation?
500
Fluid friction in the air.
What is Air Resistance?
500
The greatest velocity a falling object reaches.
What is Terminal Velocity?
500
The upward pushing force (on a rocket).
What is Thrust?
