Question

work done on a particle by the field of force is positive then what happens to its kinettic energy​

Answer 1

Answer: lowers

Explanation:

Answer 2

Kinetic energy of particle will increase.

1. The relationship between work done and kinetic energy can be described with the help of work-energy theorem.
2. The Work-Energy theorem states that the work done on an object is the change in its kinetic energy, denoted by the equation - W = Δ(K.E.).
3. The equation explains that, whenever net force acts on an object, then it is accompanied by change in the kinetic energy of the object.
4. The change can be positive or negative.
5. If work done is positive in nature, then object will gain kinetic energy.
6. This happens due to increase in momentum and velocity of the object or the atoms in the object.
7. Accordingly if work done is negative in nature, then the object will lose energy.
8. This again happens due to loss of velocity and momentum which causes loss of energy.
