Question 4

Which of the following lists contains only forms of kinetic energy?
A) electrostatic,gravitational,and mechanical energy
B) gravitational,mechanical,and electrical energy
C) thermal,acoustic,and mechanical energy
D) chemical,thermal,and acoustic energy
E) gravitational,chemical,and electrostatic energy

Accepted Answer

Thermal, acoustic, and mechanical energy are all forms of kinetic energy. Thermal energy is the movement of particles within an object, acoustic energy is the energy carried by sound waves, and mechanical energy involves the movement of objects or substances, such as in motion or vibration.

Question 5

Of the following types of energy,which is/are classified as potential energy?
1) mechanical
2) electrostatic
3) chemical
A) 1 only
B) 2 only
C) 3 only
D) 2 and 3
E) 1,2,and 3

Accepted Answer

Electrostatic and chemical energy are forms of potential energy. Electrostatic energy is due to the position of charged particles, and chemical energy is stored in the bonds of molecules. Mechanical energy can be both kinetic and potential, but it is not exclusively potential energy.
