Energy Transformations

Front

What type of energy transformation occurs when a hawk eats a mouse then uses the energy from the mouse to fly?

Back

Chemical to mechanical energy transformation occurs when the hawk converts the chemical energy stored in the mouse into mechanical energy to fly.

Front

According to the Law of Conservation of Energy, energy cannot be ______ or ______.

Back

Created or destroyed. This law states that energy can only change forms.

Front

Gravitational potential energy depends on the______ and ______ of the object.

Back

Height and mass. The higher and heavier an object is, the more gravitational potential energy it has.

Front

At which position does the roller coaster cart have the most kinetic energy?

Back

Position X. Kinetic energy is highest when the cart is moving the fastest.

Front

Which energy transformation occurs when a lamp that is plugged in the wall outlet is working properly?

Back

Electrical to light energy transformation occurs when the lamp converts electrical energy into light.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy = mass × gravity × height (PE = mgh).

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (like solar and wind), while non-renewable sources (like coal and oil) cannot be replaced once used.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to its temperature.
