Chapter 2, Problem 62A

To determine

The way,a football can be treated as a particle.

Explanation of Solution

Introduction:

A particle motion model diagram is one in which an object is represented as a particle and its motion is represented by the position of the dots in equal time intervals.

A particle motion model diagram helps in representing the position, velocity and acceleration of an object at equal time intervals. An object can be treated as a point particle if its rotational kinetic energy is negligible, the internal motions are not important and primarily the size of the object is very small in comparison to the distance covered by it.

Conclusion:

An object can be treated as a point particle if its rotational kinetic energy is negligible, the internal motions are not important and primarily the size of the object is very small in comparison to the distance covered by it.
