Opposite reaction of Air particles pushed outward against a balloon

Balloons and Rockets

The air rushes out of the neck of the balloon. The action of the air rushing from the balloon pushes against the balloon, moving it in the opposite direction. When rocket fuel is burned, hot gases are produced. These gases expand rapidly and are forced out of the back of the rocket.

Explanation:

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
