What is Newton's First Law of Motion?
The law of inertia.
An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force.
What is inertia?
The tendency of an object to resist changes in velocity.
When there is no outside forces, what will happen to an object?
It will not move.
What is force?
It is a push or pull on an object.
What is gravity?
Gravity is what keeps everything to the surface of the Earth.
What is friction?
A force that opposes motion, resulting from the contact of two surfaces.
What is kinetic friction?
Friction that opposes motion once the motion has already started.
What is static friction?
Friction that opposes the initiation of motion.
What is Newton's Second Law of Motion?
When an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration
What is the formula for total force?
Total Force= (Mass) x (Acceleration)
What is the standard unit force from a Newton?
kg x m/ second squared
What is potential force?
It is an object that has potential energy within it self.
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction.
Where was Sir Isaac Newton born?
Wools Thorpe, Lincolnshire
Who was Newton like?
Copernicus and Galileo
What law demonstrates dizziness?
Newton's First Law of Motion.
What are semicircular canals?
They are sacs of fluid in your ears that can slosh inside of them.
What law does friction apply to?
Newton's Second Law of Motion.
What is air resistance?
It is air that bounces off an object, called drag.
Did Newton cherish Copernicus and Galileo's ideas?
No he said they were foolish.
