Question

how we explain the force from the first law of motion?

Answer 1

Newton first law

For this u need to understand what is inertia

Inertia is a force which unable the body to move or be in rest and it need a external force for moving or to be in rest.

Inertia is of three types

Inertia of rest : eg. when a car starts we fall back

Inertia of motion : eg.when a bus stops we fall front

Inertia of direction:eg. while cycling the water gets turned with cycle tire and fall tangentially

Hope u can understand it
