Exploring Potential and Kinetic Energy

Introduction to Energy

It exists in two forms: potential energy and kinetic energy.

• Potential energy is stored energy,

• Kinetic energy is the energy of motion.

Understanding these concepts is crucial for exploring how energy can be harnessed and utilized to power the world. Let's dive deeper into the fascinating world of energy!

​Energy is the ability to do work or to cause change.

Multiple Choice

What are the two forms of energy?

• Potential energy and kinetic energy

• Thermal energy and electrical energy

• Chemical energy and nuclear energy

• Solar energy and wind energy

What is Energy? What is Work?

Energy is the ability to do work or cause a change.

Work is done when a force moves an object.

Law of Conservation of Energy

Energy cannot be created or destroyed. It undergoes transformations but the total energy remains constant.

Energy

Objects within a system can have both potential and kinetic energy.

The change in the position (motion) of an object causes a transformation between potential and kinetic energy.

Potential and Kinetic Energy

• Potential energy is stored energy that an object possesses due to its position or condition,

• Kinetic energy is the energy of motion.

• Potential energy can be converted into kinetic energy and vice versa. These two forms of energy are fundamental concepts in physics and play a crucial role in understanding the behavior of objects and systems.

Multiple Choice

What is kinetic energy?

• The energy of motion

• The energy of potential

• The energy of heat

• The energy of light

Understanding Kinetic Energy

• Light: Energy carried by light and other kinds of EM waves.

• Sound: Energy carried by sound waves.

• ​Thermal: Energy related to the temperature of a substance

• Electrical: Energy produced by electric charges

• Mechanical: Energy an object has because of its motion or position.

Understanding Potential Energy

1. Stored energy waiting to be released

​Gravitational -> Energy an object has due to its position and height above the Earth

​The higher off the ground, the more potential energy; the closer to the ground, the less potential energy)

Multiple Choice

What factors does potential energy depend on?

• Height, position, and mass

• Temperature, pressure, and volume

• Speed, distance, and time

• Force, work, and power

Types of Potential Energy

• Chemical Potential Energy: Energy stored in the bonds of atoms & molecules in substances

  • food

  • biomass

  • petroleum

  • natural gas

  • propane

• Elastic Potential Energy: Energy stored when an object is temporarily stretched

• Nuclear Potential Energy: Energy stored in the nucleus of an atom, released during nuclear reactions.

Multiple Choice

Which type of potential energy is stored in the nucleus of an atom?

• Gravitational Potential Energy

• Elastic Potential Energy

• Chemical Potential Energy

• Nuclear Potential Energy

Gravitational, Chemical and elastic Potential Energy can be transformed into Kinetic Energy of motion.

Potential Energy and Kinetic Energy have an inverse relationship, which means they are opposite to each other.

What is the relationship between Potential & Kinetic Energy?

Multiple Select

What does it mean when it says "Potential and Kinetic have an inverse relationship? (2 answers)

• They are opposite of each other

• It Kinetic increase so does Potential

• When 1 goes up the other goes down

• When Potential Energy decreases to dose Kinetic Energy
