A lamp is plugged into a wall socket. Once the lamp is turned on, both light and heat come from the lamp. The energy transformation is:

electrical to radiant and thermal

electrical to radiant and potential chemical

electrical to radiant and nuclear

electrical to radiant and mechanical

If you bounce a tennis ball on the ground, it will bounce back up, but not to the original height from where it was dropped. What is taking place, energy-wise speaking?

At impact, the kinetic energy is transferred to the ball itself, and converted to heat and sound. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.

At impact, the kinetic energy is transferred to the floor, and converted to heat and sound. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.

At impact, the potential energy is transferred to the ball itself, and converted to chemical and sound energies. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.

At impact, the mechanical energy is transferred to the ball itself, and converted to kinetic and sound energies. These other forms of energy are not recoverable, so the kinetic energy bouncing up is less than bouncing down.

If you want to make a homemade rocket, you can mix baking soda and vinegar. The top of the bottle will fly off. What are the energy transformations taking place?

chemical energy to kinetic energy

chemical energy to thermal energy

chemical energy to potential energy

This image/caption describes which scientific law/theory?

The Law of Conservation of Energy

The Theory of Conservation of Energy

The Law of Conservation of Mass

Which statement summarizes the Law of Conservation of Energy?

Energy is never created or destroyed; it is only transformed from one form of energy to another.

Energy is never created, but can be destroyed when heat is created in an exchange

Energy is never created or destroyed. It is only created when energy is created from matter.

Energy is never destroyed or created except when there is a nuclear reaction.

A ball sitting at the top of a ramp. As the ball rolls down the ramp, the potential energy of the ball decreases. What happens to the potential energy as the ball moves?

It is converted to kinetic energy.

It is lost as gravitational energy

It is used to make the ball slow down

it is destroyed as the ball moves

Damon is a musician playing in a band. At the end of a song, he plucks a single guitar string. The string moves rapidly back and forth. Which of these statements explained what happens to the kinetic energy of the moving string?

The kinetic energy is converted into sound energy and thermal energy

the kinetic energy is changed into potential energy and stored.

The kinetic energy is destroyed as the string moves until none remains.

Some of the energy is converted to sound energy and the rest is destroyed.

Carlos waits for the bus and discovers his hands getting very cold. He rubs his hands together vigorously in order to warm them up. Which of the following best explains what causes CHarlotte's hands to warm as she rubs them together?

kinetic energy is transformed into thermal energy

mechanical energy is transformed into nuclear energy

thermal energy is transformed into electromagnetic energy

potential energy is transformed into chemical energy

Energy transfers and transformations

What is the stored energy of an object or material due to its position.

This is the energy associated wityh the movement of electrons through a wire or circuit.

This is the energy of an object due to its motion, position, or condition. It's the combined total of potential and kinetic energy of an object.

The faster an object moves, the more of this type of energy it has.

This is the energy of an object due to the motion of its atoms and molecules.

This type of energy travels in waves and is able to move through empty space.

This is the energy of vibrations carried through solids, liquids, or gases. It travels in waves, but cannot move through empty space or a vacuum.

All energy can change from one of these to another.

This is the energy produced when an atom splits apart (fission) or when two atoms join to form one atom (*fusion).

Plants use energy from the sun in the process of photosynthesis to manufacture glucose. The energy transformation is:
