Mechanics
momentum
momentum p=mv
Impulse I=Ft=change in momentum
conservation of momentum
condition:net external force is 0
collision
inelastic collision
elastic collision
Perfectly inelastic collision
Kinematics
Linear motion
Uniform motion
Uniformaly accelerated motion
Projectile motion
horizontal:uniform motion
vertical: Free fall
Circular motion
uniform circular motion
non-uniform circular motion
work，energy&power
work W=F·s
energy
kinetic energy Ek=1/2mv^2
potential energy Ep=mgh
conservation of energy：can not be created or damaged only can be transferred
Power p=W/t
Dynamics
Newton’s law
1st: inertia
2nd: F=ma
3rd: The force and reaction force are equal in the opposite direction.
force
contact force
field force
