1) What are the 3 basic forms of energy?

Since there are so many, I'm thinking of kinetic and potential, but what would be the third?

2)The increase in potential energy of any system is equal to the output ___.

They probably want you to say kinetic, potential, and radiant.

a 70kg man is walking at a speed of 2.0 m/s. what is his kinetic energy?

a 60 kg person walks from the ground to the roof of a 74.8 m tall building. How much gravitational potential energy does she have at the top of the building?

1) The three basic forms of energy are kinetic energy, potential energy, and thermal energy.

To determine the third form of energy, we can consider that thermal energy refers to the energy associated with the motion of particles in a system. Kinetic energy is the energy possessed by an object due to its motion. Potential energy, on the other hand, is the energy that an object possesses due to its position or arrangement.

Considering this, it may seem that there are only two forms of energy: kinetic and potential. However, a closer examination reveals that potential energy can be further classified into different forms. Some examples of potential energy include gravitational potential energy, elastic potential energy, chemical potential energy, and nuclear potential energy.

Therefore, the third basic form of energy would be potential energy in its various forms.

2) The increase in potential energy of any system is equal to the output work done on the system.

Potential energy is associated with the position or arrangement of objects. When work is done on a system to increase its potential energy, the energy is transferred to the system, which results in an increase in its potential energy.

The concept of work is defined as the product of force and displacement, where force is applied in the direction of the displacement. When work is done on a system, there is an increase in the potential energy of that system.

Hence, the increase in potential energy of any system is directly related to the output work done on that system.
