Physics

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

T^2=r^3

Motion of an object when tangential speed is constant

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.

The line about which circular motion occurs.

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

An object that revolves around a central body.

A device that changes the force needed to do work
