Question

Who will have greater kinetic energy lighter body or heavy body with same speed

Answer 1

Explanation:

lighter body have greater kinetic energy

Answer 2

Solution:-

Heavy Body have greater kinetic energy than lighter body.

K.E = 1/2mv²

If the mass of body increases then the kinetic energy of body increases . Here Kinetic energy is directly Proportional to the mass of the body.

Additional Information!!

• The rate of doing work is called power .

OR

The rate at which energy is transferred by an object is called the Power delivered by that object.

• SI unit of Power is Watt (W).

• Mathematical Term

• P = W/t

• 1 horse Power = 746 Watt .

• The work done by a force acting on an object is equal to the product of force and thedisplacement of the object in the direction of the force.

• SI unit is Joule (J).
