Mechanics
Friction
F = μR
sum of F = ma
always in opposite direction of motion
If an object is in equilibrium the force is less than μR.
If an object is in limiting equilibrium, the frictional force is equal to μR
Forces and motion in one dimension
W=mg
F=ma
g=10m/s^2
component of weight projected perpendicular to the surface of slope: mgcosΘ
component weight objected vertically is mg sin teta
horizontal and vertical component
in equilibrium where the resultant force =0
vertical Upwards force = vertical downwards force
Horizotal Force going left = horizontal force going right
Theres tension in string
to find the magnitude and direction of the resultant force
use tan
pythagoras
Velocity and Acceleration
suvat equations
s=ut+1/2 at^2
v^2=u^2+2as
(v-u)/t =a
v=u +at
