Newtons 2nd Law of Motion |
The rate of change of momentum is directly proportional to the external force acting on the body and takes place in the same direction. |
|
|
Law of conservation of momentum |
The linear momentum of a system of interacting(colliding) bodies remains constant unless an external force acts upon it. |
|
|
Conservation of Angular Momentum |
The angular momentum of a system is constant unless an external torque acts upon it. |
|
|
Torque |
(Rotational) Torque= Force x perpendicular distance of line of action of the force from the axis.
Torque=moment of inertia of a system x angular acceleration T= I(alpha) |
|
|
Linear Momentum |
The linear momentum p of an object of mass m that moves velocity v is the product of of its mass and velocity i.e. P=mv, measured in kgms-1 |
|
|
Angular Momentum |
The angular momentum of a particle about an axis is the product of its linear momentum and the perpendicular distance of the particles from the axis. |
