Question

Solve it.
1. State Newton's second law.
2. Prove F = m.a where the symbols have usual meaning.
3 state the relationship between SI and CGS
Unit of force​

Answer 1

Answer:

(1) ➡️the second law of motion states that the rate of change of momentum of an object is proportional to the momentum unbalanced force in the direction of force .

(2) suppose an object of mass, m is moving along a straight line with an

initial velocity , u . it is uniformly accelerated to velocity ,v in time , t by the application of constant force , F throughout the time , t . the initial momentum and final of the object will be, p

p1 = mu

p2 = mv

the change in momentum ~ p2 - p1

~ mv - mu

~ m( v- u)

the rate of change of momentum is directly proportional to

$\frac{m \times (v - u)}{t} \\ or \: the \: applied \: force \: \\ f \: \alpha \: \frac{m \times (v - u)}{t} \\ \\ f = \frac{km \times (v - u)}{t} \\ = kma \\ \\ here \: \: k \: is \: constant \: .$

mate here

~ = directly proportional to (symbol is not present )

also alpha is directly proportional to.
