Unit 4 - Energy Quiz

The work-energy theorem states that ​ (a)   done on a system changes its ​ (b)   .

• work
• energy
• force
• acceleration

Work can be determined by :

• Subtracting kinetic energy from potential energy

• Measuring the contribution of goods and services to the economy

• Dividing velocity by change in time

• Multiplying force and displacement (distance)

Organize these forms of energy into the correct categories

Groups:

(a) Kinetic Energy

,

(b) Potential Energy

,

(c) Kinetic and Potential Energy

• acoustic (sound)

• wave (mechanical and light)

• elastic

• thermal (heat)

• electrical

• magnetic

• chemical

Kinetic energy is based on :

• Mass and velocity

• Velocity and time

• Acceleration due to gravity

• Work put into the system

For an isolated system, what is the relationship between kinetic and potential energy?

• As the kinetic energy increases, potential energy decreases.

• As the kinetic energy increases, potential energy increases.

• As the kinetic energy increases, total energy increases.

• Kinetic and potential energy are independent from eachother.

Match the types of energy with their equations

• m g h

• Kinetic energy

• KE + PE

• (Gravitational) Potential Energy

• 1/2 m v^2

• Total Energy

Work is the application of _____ over a certain distance.

What are the units for energy?

What is potential energy?

• The amount of energy stored in a battery.

• Another term for kinetic energy.

• The energy stored in an object by its position.

• The energy of motion.
