Glossary
Acceleration: The rate of change of velocity --- how fast velocity changes
Displacement: A vector which is defined by a change in position --- how far away something is from its starting point
Energy: The capacity to do work
Force: an influence on a body or system, producing or tending to produce a change in movement or in shape or other effects --- any push or pull
Impulse: A physical quantity that results from a force being applied to a body for a certain amount of time that is equal in magnitude to the product of their values --- how much momentum changes
Inertia: Resistance to acceleration
Kinematics: The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it --- deals with velocity, acceleration, distance, and time
Kinetic Energy: The energy an object has due to the fact that it is in motion
Mass: the amount of substance of stuff there is in an object Momentum: A physical vector quantity that has its magnitude determined by the product of its mass and velocity
Potential Energy: The energy an object has due to it’s placement in the gravitational field
Velocity: The rate of change of displacement --- how fast something moves from its starting point
Work: The distance over which a force acts
Newton’s First Law: An object at rest will remain at rest unless acted on by an outside force; an object in motion will remain in motion unless acted on by an outside force
Newton’s Second Law: The change in motion is proportional to the force impressed
Newton’s Third Law: To every action there is an opposite and equal reaction
The Law of Conservation of Momentum: Momentum is conserved
