Match the List I with List II

List I Variable	List II Equation
A.	Kinetic energy	I.	½ mv2
B.	Potential energy	II.	R
C.	Momentum	III.	m v
D.	Friction	IV.	M g h

Choose the correct answer from the options given below:

Correct option is B

A. Kinetic Energy → I. 12mv2\frac{1}{2} mv^221​mv2:
· Kinetic energy is the energy of motion and is calculated using 12mv2\frac{1}{2} mv^221​mv2, where mmm is mass and vvv is velocity.
2. B. Potential Energy → IV. m×g×hm \times g \times hm×g×h:
· Potential energy is the energy due to position or height, calculated as mghmghmgh, where mmm is mass, ggg is acceleration due to gravity, and hhh is height.
3. C. Momentum → III. m×vm \times vm×v:
· Momentum is the product of an object’s mass and velocity, represented as mvmvmv.
4. D. Friction → II. μR\mu RμR:
· Frictional force is given by μR\mu RμR, where μ\muμ is the coefficient of friction and RRR is the normal reaction force.
Correct Matching: · A-I: Kinetic Energy → 12mv2\frac{1}{2} mv^221​mv2
· B-IV: Potential Energy → m×g×hm \times g \times hm×g×h
· C-III: Momentum → m×vm \times vm×v
· D-II: Friction → μR\mu RμR
