Question

To find the force on any object, which of the following things are important to know?​

Answer 1

Explanation:

F=ma

in order to calculate force we have know mass and acceleration of the body

or a = v-u/t

Answer 2

F = ma

For finding force, the condition should be that a object should be in motion. Because every thing have mass. But acceleration is rate of change of velocity. So, Object should have a velocity.
