Question

25. Define kinetic energy. Write its
formula and S.l unit.​

Answer 1

Answer:

The international standard unit of kinetic energy is joules(j) (J=kg) kinetic energy =1/2*m*

Answer 2

Answer:

Definition :- The energy which an object has because of its motion is called its kinetic energy.

Formula :-

$k.e . \:= \frac{1}{2} {mv}^{2}$

SI unit :- Joule

Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m2 / s2.

CGS unit :- Erg

The erg is a unit of energy equal to 10−7 joules (100 nJ). It originated in the centimetre–gram–second (CGS) system of units. It has the symbol erg.
