# Laws of Motion

Intuitive concept of force, Inertia, Newton’s first law of motion; momentum and Newton’s
second law of motion; impulse; Newton’s third law of motion.
Law of conservation of linear momentum and its applications.
Equilibrium of concurrent forces, Static and kinetic friction, laws of friction, rolling friction,
lubrication.
Dynamics of uniform circular motion: Centripetal force, examples of circular motion (vehicle on
a level circular road, vehicle on a banked road).

### Friction and Circular Motion

Friction The property by virtue of which the relative motion between two surfaces in contact is opposed is known as friction. Frictional Forces - Tangential forces developed...

### Conservation of Linear Momentum

Law of Conservation of Momentum: The total momentum of an isolated system of particles is conserved. The law follows from the second and third law...

### Laws of Motion

Force: A force is necessary to keep a body in uniform motion is wrong. A force is necessary for the practice to counter the opposing...
