Question

What is momentum ? Write its SI unit. Interpret force in terms of momentum. Represent the following graphically
(i) momentum versus velocity when mass is fixed.
(ii) momentum versus mass when velocity is constant

Answer 1

Answer:

Explanation:

Momentum The quantity of motion possessed by a moving body is known as momentum of the body. Momentum of an object of mass m moving with a velocity v is the product of it. It is denoted by p. p = mv. Its SI unit is kg-ms-1.

Hope it's help you .

Answer 2

we know that every obeject have some mass

so when an object is moving it has some momentum

mathamatically it is express as multiplication of mass and velocity

momentum = mass × velocity    ..............1

and

momentum is directely proportional to mass and velocity

so it's unit is kg m/s

and

as per Newton's 2nd law

F = m × a    ...................2

and we know rate of change of momentum is force exerted on it

so

Δp = m × Δv    .................3

so

F = m × a = m × Δv

F = Δp

and for momentum versus velocity when mass is fixed

so that here p is directly proportional to v

and graph will be straight line pass through origine as pic attach below

and momentum versus mass when velocity is constant for differnt

mass than there p is directly proportional to m and graph will be stataight line pass through origine
