Big Idea 10 and 11

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one object or system to another, often through work or heat.

Front

What is the principle of energy conservation?

Back

The principle of energy conservation states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is heat energy?

Back

Heat energy is a form of energy that is transferred between systems or objects with different temperatures (thermal energy).

Front

What happens to light when it hits a mirror?

Back

When light hits a mirror, it reflects off the surface, allowing us to see an image.

Front

What is the definition of reflection in terms of light?

Back

Reflection is the bouncing back of light waves when they hit a surface that does not absorb the light.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred due to temperature differences, while temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

What is the effect of applying energy to an object?

Back

Applying energy to an object can cause it to move, change temperature, or change state.
