A car starts motion from rest at uniform acceleration of 2m/sec 2 for 3 seconds, and then it maintains a constant speed for 2 seconds.Then the breaks are used to decelerate the car uniformly to rest during a time of 3 seconds. Draw the graph representing the journey of the car then calculate 1)the maximum speed […]

A body travels 100m in first 2 seconds and 104 in the next 4 second.how far will it move in the next four seconds if the acceleration is uniform?

## Speed Velocity and acceleration

Sir ir it true or false – “the speed of particle remains constant.this means that no unbalanced force acts on it.” (Purshkar asks) Answer: If velocity remains constant, then we can say that no unbalanced force acts on it. If a body moves with uniform speed with its direction changing with time, as in the case […]

Motion, force and work Motion : Distance and displacement, velocity; uniform and non-uniform motion along a straight line; acceleration, distance-time and velocity-time graphs for uniform motion and uniformly accelerated motion, equations of motion by…

Newton’s Laws of motion First Law: Every body continues to be in its state of rest or state of uniform motion in a straight line unless an external force complels it to do so. Second Law: The rate of change of momentum of a body is directly proportional to the net external force acting on […]

## A Few Problems from Kinematics

A body falling freely from rest has velocity v after it falls a height h . Calculate the distance it should fall down further for its velocity to become double A particle in uniform acceleration in a straight line has a speed of v m/s at position x meter is given by √(25-16x). What is […]
