Question

what is momentum and Newton law​

Answer 1

Answer:

*⃣MOMENTUM

it is the product of mass and velocity .

Denoted by : P

Unit = kg m /sec

Dimension : M1L1T-1

p = M * V

Where M = Mass

V = Velocity

Newton's laws of motion

1⃣Newton's first law / Law of inertia

the body is rest and to be at rest or in uniform motion unless and external force is applied on it .

__________________❤

2⃣ Newton's second law

the average force on the external force is directly proportional to rate of change of momentum

F = MA

where Mass is constant

_______________________❤

3⃣Newton's third law of motion

for every action there is equal and opposite reaction

F action = - F reaction
