Texas Gateway: 4.8 Extended Topic: The Four Basic Forces: An Introduction

Scratch and sniff an introduction to organic chemical reactions. A creative lesson has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the organic...

The strong force holds quarks together to form hadron particles, which include baryons and mesons. Common baryons, such as protons and neutrons, are the focus of a video that shows how they use the strong force. Then it explains the...

The magnets on a refrigerator are stronger than Earth's magnetic force. Watch a video that describes the fundamental force of magnetism. It relates magnetism to electricity and connects this to almost every type of electricity...

The Newtonian theory and the Einstein theory of gravity are the focus of a video that examines the details of each and includes the drawbacks of them as well — a great, well-rounded lesson!

Scientists can't just change a neutron to a proton, can they? Although they don't have control of this process yet, they have identified the weak force that does exactly that. The simple graphics in an interesting video explain the...

There is a force stronger than electricity or gravity, so scientists named it the strong force. The video continues the explanation of the strong force and the way it works. It also describes the limitations, such as only working in very...

The average American will move 12 times, which results in a lot of moving furniture! Class members consider the forces required to move objects with a creative simulation that opens with the forces required to push a filing cabinet....

By the end of this section, you will be able to understand the definition of force.

By the end of this section, you will be able to observe collisions of extended bodies in two dimensions and examine collisions at the point of percussion.

By the end of this section, you will be able to define net force, external force, and system; understand Newton's second law of motion; and apply Newton's second law to determine the weight of an object.
