What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

What happens when thermal energy moves from one object to another?

Back

When thermal energy moves from one object to another, it is called heat transfer. Heat flows from a warmer object to a cooler one.

What is reflection in terms of light?

Back

Reflection is the bouncing back of light when it hits a surface. It allows us to see objects.

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

What happens in a series circuit when one bulb goes out?

Back

In a series circuit, if one bulb goes out, the entire circuit is broken and all bulbs will go out.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, all components are connected in a single path. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the energy of an object due to its motion or position. For example, a moving car has mechanical energy.
