Question

dimensions of second law of motion

Answer 1

F=ma

The Mathematical equation of Newton's 2nd law.

Where m is mass of the object and a is the acceleration.

Acceleration, a=v(velocity)/t(time),its S.I. unit is m(metre)/s(second)^2

Where v=s(displacement)/t(time),its S.I.unit is m/s.

Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation.

∆x=xf-xi

∆x-Displacement

xf-final position of the body

xi-initial position of the body

Displacement's S.I. unit is metre(m) ,which is a dimension.

Displacement is a vector quantity.

Answer 2

Rate of change of momentum is equal to force.
