name one of the scientific principles trevor talks about when describing how the yo-yo is physics at work!! ANSWER QUICK

A scientific principle that is used in describing how the yo-yo is physics at work since it possesses energy.

The yo-yo is physics at work since it exhibits different types of force such as the angular movement, frictional force and force of gravity. The gravitational force can be found in the engine of the yo-yo. When the yo-yo is released, gravity pulls it down to the ground.Also, through the angular momentum, the object can keep spinning.

Just as a yo-yo has two kinds of kinetic energy, so it has two kinds of momentum: linear momentum (because it moves in a straight line, up and down on the string) and angular momentum (because it spins around). All spinning objects have angular momentum.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
