1
Q
Momentum
A
Mass * Velocity
1
Q
First Law of Motion
A
A body will continue to be in rest or motion unless or until an external force is applied on it
2
Q
Second Law of Motion
A
Rate of change of momentum depends upon force
3
Q
Third Law of Motion
A
Every action has an equal and opposite reaction
4
Q
Force due to spring
A
f = -kx, where k = spring constant and x = elongation of the spring
5
Q
Equilibrium conditions
A
Translational and Rotational equilibrium means net force is 0 and net torque is 0
6
Q
Work Done
A
Force*Displacementcosθ, where θ is the distance between the force and displacement vector
