Physics - Uniform Circular Motion & Universal Gravitation

v = 2πrf or v = (2πr)/T ac = v²/r T=1/f or f=1/T Fc=(mv²)/r Fg=(Gm1m2)/r²

period

time to complete one revolution; T

frequency

how often it revolves/number of revolutions per second; f

linear velocity

how fast an object is moving tangential to the circle (straight); v

centripetal acceleration

acceleration that makes an object change direction; ac

centriptial force

force that causes an object to move in a circle; N

Newtons Law of Universal Gravitation

any 2 objects attract each other with a force that is proportional to their masses and inversely proportional to the square distance between them

radius

distance between two objects

Cavendish experiment

found force of the earth by hanging a weight parallel to another object and seeing if the attract to each other
