Unit 1
Physics of Something
Uniform Circular Motion
the net force and acceleration always points towards the center of circular motion
the velocity always points to the direction the object is currently moving in
centripetal acceleration:
a = v^2/r
Conversions
v = omega*r
omega = (change in angles)/(change in time) = (2*pi)/t
frequency = 1/t
tips: plug everything back into net force = mv^2/r to get what is needed
Universal Gravitation
G = universal gravitational constant = 6.67E-11 m^3/kg*s^2
F for a planet
for little g:
net force (in space) = Fg = ma
mg = ma
g= a = v^2/r
another equation for little g:
since weight of object = gravitational force exerted by earth on object:
mg = G*Mm/r^2
g = GM/r^2
g= acceleration due to gravity
M = mass of earth/any planet
tips: this can be used to find velocity if we know the gravitational force of something
or use to compare different weights on different planets
