mass: a body's quantity of matter
free falling body: an application of body movement with uniform acceleration.
speed: a vector quantity of distance traveled by a body in a unit of time.
uniform velocity: scalar quantity at which body covers the same distance in each measured unit of time for which it's measured.
inertia: a body's resistance to motion.
acceleration: any change in velocity.
motion: the change in position of a body
gravity: the force of attraction of the mass of the Earth for objects near its surface.
force: strength or energy used to cause a motion or change; usually a push or a pull.
velocity: a scalar quantity of distance traveled by a body in a unit of time.
Newton: metric unit to measure force.
body: any distinct quantity of matter
centripetal force: a center seeking force related to acceleration.
frictional force: a naturally occurring force related to two bodies in motion.
gravitational force: the force that provides the attraction between masses and keeps those masses in their orbits.
ellipse: an oval shaped orbit of planets around the sun.
work: the product of a force and the distance through which the force acts on a body.
energy: a measure of capacity to do work
joule: the metric unit of work and energy
kinetic energy: energy in motion
potential energy: stored energy with the potential of doing work
power: the rate at which work is done
efficiency: the ratio of useful output power to total input power in a machine expressed in percent.
