Relation between Kinetic Energy and Momentum

Q1

What is kinetic energy?

The kinetic energy of an object is the energy associated with the object which is under motion. It is defined as “the energy required by a body to accelerate from rest to stated velocity.” It is a vector quantity.

Q2

Define momentum.

The momentum of an object is the virtue of its mass. It is defined as the product of mass and velocity. It is a vector quantity.

Q3

State the law of conservation of momentum.

The law of conservation of momentum states that in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.

Q4

The law of conservation of momentum is based on which law of motion?

The law of conservation of momentum is based on Newton’s third law of motion which states that every force has a reciprocating equal and opposite force.

Q5

What is the formula for the law of conservation of momentum?

The momentum observation principle can be mathematically represented as:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
In the equation, m1 and m2 are masses of the bodies, u1 and u2 are the initial velocities of the body.
v₁ and v₂ are the final velocities of the bodies.
