Newton
An object will not change its motion unless a force acts on it
What is Newton's 1st Law?
When two surfaces are sliding across each other.
What is Kinetic Friction?
This is force acting on an object as it is falling towards another object.
What is Gravity?
Aristotle thought this was needed to maintain an object's constant motion.
What is constant force?
This the force responsible for the repulsion of like and the attraction of unlike electric charges
What is the electromagnetic force?
This is the law stating when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
What is Newton's 3rd Law
This is the type of friction that results from an object rubbing against another with no movement.
What is Static Friction?
This is what resists the change in direction an object is traveling in.
What is Inertia?
Sir Isaac's Newton's observations and scientific laws govern what percentage of what we see and feel every day?
What is 99%?
It is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides.
What is Gravity?
The force on an object is equal to its mass times its acceleration.
What is Newton's 2nd Law?
This type of friction is what is cause when an object is moving across an object with force with some resistance.
What is Sliding Friction?
This is the motion an object is in when it is acted on solely by gravity.
What is Free Fall?
The two measurements of an object that determine the energy with which an object moves.
What are weight and Mass?
Also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons.
What is the Electromagnetic force?
Sir Isaac Newton is noted as having written more about this than scientific theory.
What is his faith in God?
This type of friction is the result of an object rolling across a surface and encountering friction as it rotates.
What is rolling friction?
Objects falling through an atmosphere should fall at the same speed expect for this force causing a difference in speed.
What is aerodynamics?
When friction is present, this energy is always created.
What is thermal energy?
Also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It's 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.
What is the strong nuclear force?
Sir Isaac Newton is from this country.
Where is Woolsthorpe, Lincolnshire, England?
Frictions occurs at this level of matter.
What is the atomic layer?
The direction of energy acting upon an object.
What is a Vector?
This is the type of friction between two viscous materials that are moving relative to each other.
What is fluid friction?
EXTRA (Not in the book): Physicists working to find a so-called grand unified theory aim to unite the electroweak force with the strong force to define this.
What is the electronuclear force?
