ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation Motion- in such

the World in Motion Human beings are in constant search for sources that can provide them with adequate resources to meet their basic needs. The desire to get an adequate supply of resources has made people move from one location to another. However‚ people’s needs are complex and differ. This observation makes it difficult to have a specific factor to attribute human movement from one area to another. Bailyn asserts that the human world can best be described as the world in motion.

Projectile motion is a form of motion in which an object is thrown near the earth’s surface‚ causing it to move along a curved path under the action of gravity only. An example would be a football quarterback‚ when a quarterback throws the football in the air it goes upward and then travels back downward due to gravity. Gravity is the only force of significance that acts on the object which causes a downward acceleration. For example if Cam Newton throws a football over a long
