Science energy and forces

Front

What is sound energy?

Back

Sound energy is the energy produced when objects vibrate, creating sound waves that travel through the air or other mediums. An example is playing the drums.

Front

What is light energy?

Back

Light energy is the energy that comes from light sources. It allows us to see and can be produced by the sun, lamps, and other light-emitting objects.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from heat. It is used in cooking, like grilling a steak, where heat is applied to cook the food.

Front

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object. It can be seen in moving cars, running children, or a swinging pendulum.

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, which can attract or repel certain materials, like iron and steel, but not non-metal objects like a penny.

Front

What materials do magnets attract?

Back

Magnets attract ferromagnetic materials such as iron, nickel, and cobalt.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, sound, and light energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a ball held at a height has potential energy due to gravity.

Front

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

Back

Renewable energy comes from sources that can be replenished, like solar and wind, while non-renewable energy comes from sources that can run out, like coal and oil.
