Acceleration directed toward the center of a circular path
The motion of a body when only the fource of gravity is acting on it
Motion of an object revolving about a single axis
the speed of an object in circular motion
Kepler's 3rd Law
Motion of an object when tangential speed is constant
Uniform Circular Motion
Force that causes centripetal acceleration
The mutual force of attraction between particles of matter
The speed needed to "break free" from a gravitational field.
An object whose escape velocity is greater than the speed of light
Each planet travels in an elliptical orbit around the sun, and the sun is at one of the focal points.
Keplers 1st law
The line about which circular motion occurs.
Axis of rotation
The time it takes to complete one cycle of revolution or wave oscillation
The product of the force and the lever arm
One of six types of machines designed to make work easier
Perpendicular distance from the axis of rotation to a line drawn along the direction of force
an imaginary line drawn from the sun to any planet sweeps out equal areas in equal time periods
Kepler's 2nd law
An object that revolves around a central body.
A device that changes the force needed to do work
