Question

1 equation of motion derive by graphical method

Answer 1

Answer:

Use the law of momentum :

p = mv

Now According to Newton’s 2nd Law of Motion:

Force is directly proportional to rate of change of momnetum, that is

F α dp/dt

F  = k dp/dt

F = k d(mv)/dt

F = k md(v)/dt

F = k ma

Experimentally k =1

F = k ma

Which is the required equation of force.

Answer 2

v=u+at

${v}^{2} - {u}^{2} = 2as$
