It is the amount of gravitational force acting on the mass of an object.

How will you calculate the resultant force if the forces are acted on the same axis and the same direction?

It is the amount or quantity of matter in an object.

State Newton's first law of motion.

How much is the resultant force if the object is moving at a constant speed in a similar direction?

Describe the forces acting on an object is the object is stationary or moving at the same speed in a similar direction.
