|
Acceleration
|
Increase in the rate or speed of something.
|
|
|
Force
|
Strength or energy as an attribute of physical action or movement: "he was thrown backward by the force of the explosion".
|
|
|
Normal Force
|
A force that is perpendicular to the surface of the Earth at any given location
|
|
|
Friction
|
The resistance that one surface or object encounters when moving over another.
|
|
|
Newton
|
The newton is the International System of Units derived unit of force.
|
|
|
Net Force
|
The sum of the vectors of all forces acting upon an object.
|
|
|
Newton's First Law
|
a body remains at rest or in motion with a constant velocity unless acted upon by an external force.
|
|
|
Newton's Second Law
|
the rate of change of momentum is proportional to the imposed force and goes in the direction of the force.
|
|
|
Newton's Third Law
|
action and reaction are equal and opposite.
|
|
|
Uniform Acceleration
|
acceleration that doesn't change
|
|
|
Centripetal Force
|
A force that acts on a body moving in a circular path and is directed toward the center
|
|
|
Centrifugal Force
|
The force that causes an object moving in a circular path to move away from the center of the path
|
|
|
Angular Momentum
|
The quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.
|
|
|
Energy
|
The capacity or power to do work, such as the capacity to move an object
|
|
|
Kinetic Energy
|
energy in form of motion
|
|
|
Potential Energy
|
stored energy due to an object's position or state
|
|
|
Work
|
force being exerted through a distance
|
|
|
Mechanical Energy
|
the amount of potential and kinectic energy in a system
|
|
|
Law of Conservation of Energy
|
says that energy cannot be destroyed or created under normal conditions
|
|
|
Joule
|
the si unit for energy and work
|
|
|
Elastic Energy
|
energy that is stored inside an object that has the ability to be stretched and pulled
|
