Understand frictional forces on objects.

Forces are everywhere. Learn what they are, the characteristics of forces, different kinds of forces, and factors that affect them.

With this hands-on lesson, help students understand force, gravity, friction, and speed. Students will also learn how each of these concepts affects the another.

Learn why every force is a push or a pull.

First, read some fast facts about forces, then take a ten-question, multiple-choice quiz. Check to see if your answers are correct after each question.

Explore the effects of forces around us in the world.

Learners investigate forces and Newton's laws. Some topics examined are mass, friction, and Newton?s laws of motion. The resource includes example problems with solutions and a chapter quiz.

What is friction? Illustrated discussion of friction including the three types, its importance, and why it is avoided.

What is force? Illustrated discussion of how force is calculated and three familiar types.

Young scholars learn about friction and drag - two different forces that convert energy of motion to heat. Both forces can act on a moving object and decrease its velocity. Students learn examples of friction and drag, and suggest ways...

Learn how wheels and axles help with force and motion.

Provides a long list of physics formulas for easy reference.

To learn how friction affects motion, students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces...

A short biography about Charles Coulomb, known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion.

A teacher lesson plan which includes activities pertaining to common methods of charging objects - induction, conduction, and friction.

This virtual experiment is designed to let the student measure the relation between muzzle velocity (which determines projectile energy), gravitational potential and the effects of frictional drag caused by wind speed blowing opposite to...
