Motion in One Dimension - Rectilinear Motion pg 2

A packet dropped from any moving vehicle or balloon, tends to possess the same velocity (speed + direction) as that of the moving vehicle or balloon, due to inertia of motion. Numerical problem 17) form the chapter Motion in 1-dimension from Nootan Physics.
Such problems give insight to learner to understand the concept of Inertia of Motion as well as co-ordinate sign convention.



Motion in One Dimension - Rectilinear Motion pg 3

This section of the motion in one dimension or rectilinear motion deals with the motion where the body is subjected to non-uniform acceleration, i.e. in some part of the motion the body tends to move with some acceleration, while the other part of the motion body tends to move with some other acceleration. It is also advisable to the students that such motion is well understood if the student draws an acceleration-time graph first and then tries to solve the problem.

Forces pg - 4

This section deals mostly with conservation of momentum esp. with collision, and once must take care of the fact that momentum is a vector quantity, and use proper vector notation while solving the numerical problems.

Forces - pg 2

This section deals mostly with Newton's second law of motion and conservation of momentum, and once must take care of the fact that momentum is a vector quantity, and use proper vector notation while solving the numerical problems.
Derivation of Conservation of Momentum using Newton's Second Law of Motion is illustrated here:
