1. (i) What is kinetic energy.

the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

(ii) Derive a formula for kinetic energy.

Kinetic energy is the energy possessed by an object by virtue of its motion.

Kinetic energy is the energy possessed by an object by virtue of its motion.K.E=1/2 mV²

(iii) An object of mass 15 Kg is moving with a uniform velocity of 4 m/sec What is

Kinetic energy possessed by the object?

Kinetic energy = 1/2 mv^2

Kinetic energy = 1/2 mv^2= 1/2*15kg*2*2

Kinetic energy = 1/2 mv^2= 1/2*15kg*2*2=120 J

Kinetic energy = 1/2 mv^2= 1/2*15kg*2*2=120 JThe kinetic energy of the object is 120J.
