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

An interactive tool where students can explore how a spring behaves, and how changing the elasticity, mass, push/pull force, and friction affect its motion or period. As the spring moves, its motion is shown on a distance-time graph.

In the following interactive students will begin to calculate coefficient of friction on a car tire. They will also calculate ideal speed and angle of a car on a turn.

Students use LEGO MINDSTORMS robotics to help conceptualize and understand the force of friction. Specifically, they observe how different surfaces in contact result in different frictional forces. A LEGO robot is constructed to pull a...

Students learn about various forces and how they relate to everyday life in this interactive learning module.

Students study how the nature of two materials in contact, and the smoothness of their surfaces affect the magnitude of the sliding force of friction. They use a force sensor to measure frictional force for different surfaces.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

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.

In this hands-on activity - rolling a ball down an incline and having it collide into a cup - the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements...
