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.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
