TRIPURA Class 11-science Physics Laws of Motion
Newton's First Law of Motion
State Newton's first law of motion. Define inertia and its relation to mass. Define and differentiate between an inertial and non inertial reference frame.Newton's Second Law of Motion
Define Momentum, Newton second law. Establish the relation between the rate of change of momentum of an object and the net external force applied.Impulse and Newton's Third Law
Define impulse due to a force. Establish its relation with momentum. State Newton's third law of motion and illustrate with examples.Common Forces in Mechanics
Define and identify the condition of equilibrium of a rigid body. Identify and resolve all the common forces on a body in equilibrium.Circular Motion
Define uniform circular motion. Identify importance of centripetal force during circular motion. Discuss banking of smooth and rough curved roads.Free Body Problems
In a free body diagram, forces acting on the body due to all the various bodies that interact with it are represented by vectors in both magnitude and directions.
While drawing Free Body diagrams: include all the contact and non-contact forces acting on the body.
While drawing Free Body diagrams do not include any force that the chosen body exerts on any other body.

General method for solving for unknowns in free body diagrams:
first draw a FBD showing all external forces acting on the body.
choose a co-ordinate system and resolve all forces in the FBD along the coordinate axes.
use Newton's second law along each coordinate axis
solve the force equations to obtain unknowns.

The component of contact force parallel to the surface constitutes the frictional force
Limiting value of static friction between two given surfaces exceeds the kinetic friction.
The direction of frictional force is always opposite to the relative motion between the two surfaces.
