Energy Transformations and Types of Energy

These flashcards cover key concepts regarding energy transformations, types of energy, and various examples illustrating how energy changes form in everyday contexts.

Energy Transformation

The process of changing energy from one form to another.

Potential Energy

stored energy that results from the position or shape of an object

Kinetic Energy

Energy of motion.

Law of Conservation of Energy

Energy cannot be created or destroyed, only transformed.

Gravitational Potential Energy

Potential energy associated with an object's height above ground.

Elastic Potential Energy

Stored energy in a stretched or compressed object EX:(rubber bands

Mechanical Energy

Kinetic or potential energy associated with the motion or position of an object. This is energy of doing work

Mechanical energy formula

Potential energy + kinetic energy

Sound Energy

Energy caused by an objects vibrations. EX: noises you hear

Thermal energy

Heat energy

Chemical Energy

Energy stored in chemical bonds. EX: what makes batteries work

Electrical energy

Energy caused by movement of electrons. EX: form a wall outlet, electricity for lightning

Radiant Energy

Energy carried by light EX: microwave, light

Light energy

Form of electromagnetic radiation. EX: light from lightbulbs, sunlight, lasers

Examples of Energy Transformations

Demonstrations of how energy changes from one form to another in various contexts.

Photosynthesis

Process by which plants convert light energy into chemical energy.

Hair Dryer

Transforms electrical energy into heat and sound energy.

Washing Machine

Uses electrical energy to produce mechanical energy and sound.

Fireworks

Transform chemical energy into light, sound, and heat energy.

Car Engine

Transforms chemical energy in fuel into mechanical and heat energy.

Mechanical to sound

When a cricket runs its wings together to create noise which energy transformation occurs?

Chemical to mechanical

When a lion uses its stored energy to chase a zebra which energy transformation occurs?

Mechanical- light- electrical- thermal- sound

Types of kinetic energy

Gravitational, elastic, chemical, nuclear

Types of potential energy

Electrical to mechanical to sound

What types of energy are transferred when you use a pencil sharpener that is plugged into the wall?
