Friction that opposes motion once the motion has already started
What is Kinetic Friction
How many laws of motion did Newton have
What is 3
A push or pull that acts on an object
What is Friction
The four types of force in nature
What is electromagnetic, strong nuclear, weak nuclear and gravitational force.
The force that can attract and repel
What is electromagnetic force
The motion of an object when it is falling solely under the influence of gravity
What is Free Fall
states that every object in the universe attracts every other object.
What is Newton's law of universal gravitation
The amount of an object
What is MASS
Force that exists between particles with electric charge
What is electromagnetic forces
the force that holds the nucleus together
A push or pull that acts on an object
What is FORCE
An object in motion (or at rest) will stay in motion (or at rest) until it is acted upon by an outside force.
What is Newtons First Law of Motion
The force of gravity acting on an object
What is weight
Strongest of the four fundamental forces.
What is Strong Nuclear Force
Newton's full name
Sir Isaac Newton
The tendency of an object to resist changes in it's velocity
What is Inertia
When an object is acted on by one or more unbalanced forces, the net force is equal to the mass of the object times the resulting acceleration.
What is Newton's second Law of Motion
The force that causes objects to have weight
What is Gravity
What is the weak nuclear force
F= MXA
What is Net Force (= Mass X Accelaration)
Friction that opposes the initiation of motion
What is Static Friction
For every action there is an equal and opposite reaction
What is Newton's third law of motion,
Static friction, Sliding (or kinetic) friction, rolling friction and fluid friction.
What are the four types of friction
The weakest of the four fundamental forces but the one most easy to recognize
What is gravitational forces
9.8m/s2 or 32ft/s2
