Answer 1

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐

❄❄❄❄❄ ENERGY ❄❄❄❄❄

➡ Energy of a body is defined as its capacity or ability to do work. Energy are typically of eight types :

(A) Mechanical energy
(B) Chemical energy
(C) Wind energy
(D) Heat energy
(E) Light energy
(F) Sound energy
(G) Magnetic energy
(H) Thermal energy

==================================

❄❄❄❄ KINETIC ENERGY ❄❄❄❄

✔ THE ENERGY POSSESSED BY A BODY BY VIRTUE OF ITS MOTION IS CALLED AS KINETIC ENERGY.

==================================

❄❄ EXPRESSION OF KINETIC ENERGY ❄❄

✔ KINETIC ENERGY ➡ (1/2)×mass×velocity².

==================================

❄❄❄❄❄ ANSWER ❄❄❄❄❄

✔ If the velocity of a body is doubled then the kinetic energy of that body gets increased by four times.

==================================

❄❄❄ IMPORTANT QUESTION ❄❄❄

➡ Which one of the following affects the kinetic energy of a body more?
(A) Mass
(B) Velocity
(C) Both
(D) None

➡ Answer : (B) Velocity
