|
Newton's second law |
Force=Mass*Acceleration (N)=(kg)*(m/s/s) |
|
|
|
Equilibrium |
A particle in equilibrium has a constant velocity (could be at rest), and has a resultant force of 0N acting on it (Forces are balanced) |
|
|
|
Friction equation |
f=uN Friction(force)=Coefficient of friction*Normal force |
