Question

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

Answer 1

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.

Answer 2

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.
