Mr. Andersen explains the difference between potential and kinetic gravitational energy. He also uses physics to calculate the energy in various objects.

In this video Paul Andersen compares and contrasts transverse and longitudinal waves. Waves carry energy through oscillations. In transverse waves the oscillations are perpendicular to the direction of the wave and in longitudinal they...

There are renewable energy sources here on Earth, but to meet our clean energy needs we should consider every possible option, including the Moon.

Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.

This video provides an introduction to Newton's three laws of motion, explaining how they help us understand the movement of objects in our everyday lives. It discusses the first law of inertia, which states that an object remains still...

This video discusses Newton's first law of motion, also known as the law of inertia. It explains how Newton built upon the experiments of Galileo to formulate this law. The video illustrates the concept using the example of a ball on the...

This video provides an explanation and examples of Newton's third law of motion, also known as the law of action and reaction. The law states that for every action, there is an equal and opposite reaction. The video illustrates this...
