Learn about forces (push or pull), gravity, and friction in this module by training dolphins.

You have probably heard the word "force" before in conversations. Here are a few examples: "the rocket had a lot of force at blast off" or "the force of the storm blew the roof off the building." What is force? Force is defined as a push...

A learning module reviewing how much force is needed to push or pull objects. Also learn about the force of gravity.

This tutorial is to introduce students to the concept of forces. Tutorial includes activities, content and teacher notes.

This lesson will explain how to calculate net forces on an object being pushed or pulled. It is 2 of 4 in the series titled "Calculating Forces."

This lesson will explain how to calculate net forces on an object being pushed or pulled. It is 1 of 4 in the series titled "Calculating Forces."

Activity 1 of this module investigates: How does potential energy change when things are pushed or pulled? Exploring how force is related to potential energy, this activity investigates how potential energy is changed when a spring is...
