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 force that opposes motion, resulting when surfaces of objects rub against each other.
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
It states that every object in the universe attracts every other object.
What is Newton's law of universal gravitation?
The amount of matter an object has.
What is MASS?
Force that exists between particles with electric charge
What is electromagnetic forces
The force that holds the protons and neutrons of the nucleus together.
What is strong nuclear force?
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
The theory that attempts to explain gravity at the smallest scale (called quantum mechanics).
What is Quantum Gravity?
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
Answer: F=m x a
What is the equation for Net Force?
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, Kenetic (or sliding) 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
Answer: d=1/2 x a x t2
What is Distance from Free Fall?
