it is called Motion against gravity
It could be called superfluous. No force is necessary to maintain motion.
Gravity is a force measured in Newton's (N)
Gravity.
it is called a resistive force
Gravity really is one of the four main forces of the Universe. gravity is an effect and not the cause of anything, no gravitation's, no gravity waves, none of it. gravity is a dynamic effect. the acceleration of the underlying for of energy focused to the center of a mass. there is no separate force called gravity, just a dynamic effect we call 'gravity'
Gravity
gravity
The product of (mass) x (force) has no physical significance.The product of (mass) x (acceleration due to gravity) is the force due to gravity,which we usually call "weight".
It's what we have learned to call "weight".
We call it the "weight" of the case.
it's actually not a force, it is a property of matter. The property is call inertia.
