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

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.

Learn how wheels and axles help with force and motion.

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

Provides a long list of physics formulas for easy reference.

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...

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...

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...
