Question

derive the formula f=ma 8 th class science

Answer 1

this is proved by Newton second law of motion

Answer 2

Hello friend,

Following is the answer;

Consider a body of mass ‘m’ moving with velocity v.

The body has a linear momentum of;

p = mv

Now as per 2nd Law of Newton;

Force is directly proportional to rate of change of momnetum,

F α dp/dt

F  = k dp/dt

Putting the value of p

F = k d(mv)/dt

F = k md(v)/dt

cross multiplying  

F = k ma

If k =1

F = (1) ma

F=ma

Hence proved.

I hope the answer is helpful

Thanks

Which is the required equation of force.
