100
The mathematical equation for velocity of a falling object
What is (change in v) = g x t
100
A quantity defined as the product of the mass and velocity of an object
What is momentum?
100
Is what acts on an object to cause it to move or to stop
What is an unbalanced force?
100
The two things that acceleration is dependent on according to this law
What is Mass and Force?
100
Newton's Third Law simply stated
What is all forces act in pairs?
200
The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite indirection to the force of gravity
What is terminal velocity?
200
The equation for momentum
What is p = m x v?
200
The force that causes it to be very difficult to actually see the first law in action
What is friction?
200
Newton's second law is describing this when an unbalanced force acts on an object
What is the motion of the object?
200
The types of force that are exerted after another force has already occurred
What is equal and opposite?
300
The force that opposes the motion of objects through air
What is air resistance?
300
When objects collide the total amount of momentum stays the same
What is The Law of Conservation of Momentum?
300
The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object
What is inertia?
300
The mathematical expression for this law
What is a = F/m?
300
The total net force on an object if action and reaction forces acted on the same object
What is 0 N?
400
The curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
What is projectile motion?
400
The transfer of momentum causes objects to move in different directions at different speeds
What is bouncing off each other?
400
The amount of net force acting on objects described by this law
What is 0 N?
400
The mathematical equation for the 2nd law rearranged to find force
What is F = m x a?
400
Explains why it is not always easy to see the reaction force to an action force (you see a ball falling towards the Earth, but you don't see the Earth pulled towards the ball)
What is Newton's 2nd Law?
500
The unbalanced force that causes objects to move in a circular path
What is centripetal force?
500
The mass of the combined objects is equal to the masses of the two objects added together
What is objects sticking together?
500
A golf ball sitting on a tee
