This is true
It's because you can't create a force with your muscles that exceeds the forces of gravity attracting the box and the Earth toward each other.
Lift is the upward force that opposes the force of gravity.
Well, it's true that the gravitational force acting on the box acts in the direction opposite to the direction of your lifting force, but there's nothing malicious or contrary about it. In fact, the gravitational force was there before you came on the scene, and as you lined up your lift, it was you who decided to oppose it.
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.
Any force with an upward vertical component does.
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
the force that opposes the motion of two touching surfaces is velocity.
Gravity pushes in, fusion pushes out.
The force of gravity keep a bycicle on the ground.
Friction and the molecules slowing down the leaf.
gravity means the force that keeps the force up on the ground and the grip on the ground are ruff
Another name for the normal force could be the force perpindicular to the surface an object is resting on.
