True or False

a. GPE (J) = 1/2m (kg) ´ 1/2h (m)

b. GPE (J) = m (kg) ´ 9.8 m/s2 ´ h (m)

c. GPE (J) = h (m) ´ 9.8 m/s2

d. GPE (J) = 1/2h (m) ´ w (m)

A. EPE is energy stored by things that stretch or compress. CPE is energy stored in chemical bonds.

B. EPE is energy stored by objects due to their position above Earth’s surface.CPE is energy stored in chemical bonds.

C. EPE is energy stored in chemical bonds. CPE is energy stored by objects due to their position above Earth’s surface.

D. EPE is energy stored by things that stretch or compress. CPE is energy stored by objects due to their position above Earth’s surface.

A. Both are stored energy that is converted into one of the 4 types of energy for use.

B. Both are measured in calories.C. Both become kinetic energy

when they are finally released.D. Both are calculated using math

A. Mass and accelerationB. Mass and distance C. Acceleration and distanceD. Mass and Velocity

A. Mass (m)B. Distance (d)C. Height (h)D. Gravitational acceleration

(g)

A. GPE is based on mass, gravity, and the distance the object has to move or fall. The book has a greater mass than the feather; hence it has a greater GPE.

B. GPE is based on speed, gravity, and the distance the object has to move or fall. The book has a greater speed than the feather; hence it has a greater GPE.

A. Mechanical EnergyB. Electrical EnergyC. Chemical EnergyD. Kinetic Energy

A. Kinetic Energy is stored energy and potential is the energy of motion.

B. Potential energy is stored energy and kinetic energy is the energy of motion.

C. Potential energy is stored energy and kinetic energy is wasted.

D. Potential energy is useless and kinetic energy is the energy of motion.

Section 2

A. RadioB. ToasterC. TelevisionD. Alarm clock

A. The total amount of potential and kinetic energy in a system.

B. The energy used by mechanical objects like cars.

C. The total amount of potential energy of an object.

D. The total amount of chemical energy used for you to move.

A. It decreases.B. It increases.C. It remains the same.D. It vanishes.

True or False?

True or False

a. remains constant b. changes constantly c. increases d. decreases

A. It is not always conserved, though. It is lost when you slow down on a bicycle.

B. Friction causes it to become lost to the air.

C. It is converted into another form of energy, but the total amount of energy remains the same.

D. It becomes thermal energy.

a. matter b. nuclei c. energy d. light

A. Fusion is the joining of nuclei and fission is the splitting of nuclei.

B. Fission is the joining of nuclei and fusion is the splitting of nuclei.

C. Fission releases energy and fusion absorbs energy.

D. Fusion is the splitting of nuclei and fission is the joining of nuclei.
