What forces objects that go up and come back down?

Objects that go up and come back down are influenced by gravity. Gravity is the force that pulls objects back towards the Earth when they are lifted up and opposing forces such as air resistance or friction can also play a role in the object's motion.


When a skier goes up a hill and down a hill what energy is that?

The skier going up the hill gains potential energy due to its height increase, which is stored energy that can be released when the skier goes back down the hill. As the skier goes down the hill, the potential energy is converted into kinetic energy, which is the energy of motion.


Must things that go up come down?

well what is true is that what goes away come back , see gravity affects every place in the universe, traveling in a straight line is impossible because gravity will affect and divert your way then you will revolve until you come back, however on the customary level what goes up may not come down if it acquired the required speed 11 meter per second


What motion is a seesaw?

A seesaw is a back-and-forth motion, where one end goes up while the other end goes down and vice versa, creating a reciprocal movement.


Why do things that go up always come down?

Objects that go up always come down due to gravity, which is the force that brings objects back towards the Earth's surface. When something is thrown upwards, gravity acts as a constant force pulling it back down until it reaches the ground. This phenomenon is known as projectile motion.

Does anything defy the law of what goes up must come down?

This is not a law. This is a statement indicating the action of gravity. Gas bubbles move upwards when released under water, and don't come back down. But these gases don't leave the Earth. Helium goes up, and doesn't come back down. But it doesn't leave the Earth. Hydrogen goes up, and the thermal energy available far up in the atmosphere will allow some hydrogen to reach escape velocity. Once hydrogen escapes, it will not come back down. Several spacecraft have gone up and are never expected to come back down. There was a manhole cover over the bore where underground atomic testing was occuring. That manhole cover went up, and had it not vaporized in our atmosphere, it would never have come back down. So, "hydrogen goes up, and some of it never comes back down". reply: mmmm, not very satisfactory im afraid,good effort though,seems nothing truly applies to the "law" . cheers!
