Force questions | form one Physics

1.i. what is force? and explain its effect on an object.

  ii.how do we generate force?

  ii) explain the unit of force briefly.

Answer / Solution

1.i.Force is a push or pull.It can cause an object either to move forward, backward or remain stationally. Why stationally? this occurs when the force applied to an object is less than that of the object.

 ii.We generate force by taking Mass times Acceleration.

    ie force=mass*acceration

               F=ma

iii) the unit of force is Newton(N) OR kgm/s².since 1N=1kgm/s².
