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.

Learners observe objects in motion down a ramp to discover how the force of friction affects an object's motion. Includes the lesson plan, vocabulary list, and extensions for students.

Activity investigates the concept of how bicycle brakes use force and friction to stop or slow mechanical motion. Young scholars work in teams to devise a simple braking system while suggesting improvements to current bicycle brake design.

This site is an interactive app of an inclined plane showing the effect of the angle, the weight of the block, and the friction as a block is pulled up an incline.

In this lesson, students make predictions about falling objects of different sizes and masses to learn about gravity and air resistance. Includes audio vocabulary list and extension activities.

In this hands-on activity students learn about the laws of physics by creating a marble roller coaster.
