Question

what is the kinetic energy of an object​

Answer 1

Kinetic energy is the energy an object has because of its motion. ... After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.

Answer 2

　　　　☆ Kinetic energy

Definition :-

-There are many forms of energy, but the main type of energy is into two categories: kinetic and potential

- kinetic energy of an object is the energy that it caused due to its motion. in simple word , It is a property of a moving object or particle and depends not only on its motion but also on its mass.

• for example :-flowing water , moving object like car and pendulum. motion––of waves, electrons, atoms, molecules, substances, and objects

Types :-

- There are five types of kinetic energy :- radiant, thermal, sound, electrical and mechanical and heat is the most common form of kinetic energy.

Relation :-

- There is a relation between kinetic energy and momentum as both the properties are linked with velocity.Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.

• Kinetic Energy is: KE = 1/2 mv2.

- temperature of a substance is related to the average kinetic energy of the particles of that substance because the particle stores energy and when heated it increases the motion of the particles.

- the kinetic energy of a rotating rigid body is directly proportional to the moment of inertia and the square of the angular velocity

• K=12Iω2 is the relation between inertia and K.E
