IIT JEE is a Joint Entrance Examination that is Conducted by the CBSE for Admission into the Undergraduate Courses of IITS

Kinematics is one of the easiest and important chapters of Mechanics in the syllabus of IIT JEE, AIEEE and other engineering examinations.

It is the branch of physics which deals only with the description of motion of bodies. In this branch we shall study some characteristics associated with moving bodies, e.g., displacement, velocity, acceleration etc.


Following topics are covered under Kinematics:-

Introduction to Motion in One Dimension

Graphical Representation and Equations of Motion

Motion under Gravity

Motion in a Straight Line with Acceleration

Motion in Two Dimensions

Motion of Projectile

Circular Motion

Relative Motion


Sample Questions on Kinematics


Problem 1.

A train covers 60 miles between 2 p.m. and 4 p.m. How fast was it going at 3 p.m.?


Problem 2.

Is it possible that the car could have accelerated to 55mph within 268 meters if the car can only accelerate from 0 to 60 mph in 15 seconds?


Problem 3.

A car travels up a hill at a constant speed of 37 km/h and returns down the hill at a constant speed of 66 km/h. Calculate the average speed for the whole trip.


Problem 4.

An archer shoots an arrow with a velocity of 30 m/s at an angle of 20 degrees with respect to the horizontal. An assistant standing on the level ground 30 m downrange from the launch point throws an apple straight up with the minimum initial speed necessary to meet the path of the arrow. What is the initial speed of the apple and at what time after the arrow is launched should the apple be thrown so that the arrow hits the apple?



Problem 5.

A box sits on a horizontal wooden board. The coefficient of static friction between the box and the board is 0.5. You grab one end of the board and lift it up, keeping the other end of the board on the ground. What is the angle between the board and the horizontal direction when the box begins to slide down the board?




Problem 6.

A 8 kg block is at rest on a horizontal floor. If you push horizontally on the 8 kg block with a force of 20 N, it just starts to move.

(a) What is the coefficient of static friction?

(b) A 10.0 kg block is stacked on top of the 8 kg block. What is the magnitude F of the force, acting horizontally on the 8 kg block as before, that is required to make the two blocks start to move?


Problem 8.

We drive a distance of 1 km at 16 km/h. Then we drive an additional distance of 1 km at 32 km/h. What is our average speed?




Problem 9.

An airliner reaches its takeoff speed of 163 mph in 36.2 s. What is the magnitude of its average acceleration.


Problem 10.

A car is initially traveling due north at 23 m/s.
(a) Find the velocity of the car after 4 s if its acceleration is due north.
(b) Find the velocity of the car after 4 s if its acceleration is instead due south.
