Question

Select examples of energy changing forms. Select the THREE answers that are correct.

Answer 1

Answer:

A. From a high perch, a raptor dives toward its prey.

C. A green plant absorbs light to make sugar molecules.

E. A human jogs down the street for exercise.

Explanation:

Energy changing is also called energy conversions. This is the process where one form of energy is transformed or converted into another form. As the law of conservation of energy states, energy cannot be created nor destroyed, it can only be transformed or transferred-- what happens is that it changes from one form to another.

In the case of A. The energy change could be from potential energy to kinetic energy. Where as when the raptor was on a high perch, it had potential energy, but when it dove down to its prey, it is now kinetic energy.

In the case of C, the plant absorbed light, where the light here is what we call radiant energy. The radiant energy is then used to make sugar molecules, which is a form of chemical energy.

For E. the human jogging down the street for exercise makes use of chemical energy, or the energy that is stored in the body. When we exercise we make use of that chemical energy to move, which comes out as kinetic energy.
