When jumping vertically, the main forces involved are the gravitational force pulling you down and the muscular force generated by your leg muscles to push you up against gravity. Additionally, there is also the ground reaction force pushing you upward as your feet leave the ground.
Jumping is a biological, biomechanical process that involves the conversion of stored energy in muscles into kinetic energy for propulsion off the ground. Scientists can study the physics and forces involved in jumping, as well as the physiological adaptations that enable humans and animals to perform this action efficiently.
The two forces that cause an increase in normal force are the force of gravity acting vertically downwards and an additional force acting vertically upwards. When these forces increase in magnitude, the normal force provided by a supporting surface also increases to counteract them and maintain equilibrium.
When jumping on a trampoline, the main forces at play are gravity pulling you towards the Earth, and the trampoline mat pushing you back up. The tension in the springs also helps to propel you higher into the air.
-- the gravitational attraction between the football and the Earth, acting vertically downward; -- the normal force of the ground or the shelf under the football, acting vertically upward. These two forces are precisely equal and opposite. If they're weren't, then the football would be accelerating vertically, not at rest.
No, objects do not have to touch for a force to be involved. Forces, such as gravitational or electromagnetic forces, can act between objects even when they are not in direct contact.

Yes, the gluteal muscles are "abductor" muscles which extend the legs away from the body and are involved along with the quadriceps in forward/rearward motion, and in jumping.
Jumping with trampolines.

You can have muscular power when your jumping vertically up to try and defend and get the ball. PS: I LOVE JUSTIN BIEBER <3

American ground forces were directly involved in the war between 1965 and 1973.
