Question

the total amount of work down on a body is equal to 24J, then change in its energy is...?
Physcis, class 9, work and energy ncert chapter

Answer 1

Answer:

The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle

Answer 2

The work done on an object is equal to the change in the kinetic energy of the object.

This is the statement for the work-energy theorem.

It can be presented in the form of the equation as follow:

$W_{net} =K.E._{final} -K.E._{initial}$

Hence, in the above question, the change in the energy would be 24 Joules.

The change in energy would be in the form of Kinetic Energy.

Thus, the correct answer is 24 Joules.
