Ron Toomer, a famous roller coaster designer, suffered from motion sickness. Pupils design their own roller coasters, learning about potential and kinetic energy in the process. Labs focus on the importance of drop height, energy...

We all recognize what friction is, but do you really understand what causes it? This project focuses on friction, its causes and forces and specifically how it affects how fast you can slip down slides.

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction.

The Thinking Fountain provides this simple experiment for understanding friction and it relationship to energy.

This Science Buddies project explains how to build a mechanism that will reproducibly swing a hammer so you can determine the amount of force needed to hammer a nail through various densities of wood. The Science Buddies project ideas...

A lesson about friction can be found on this website. Students will experiment to see how motion and frictional force affect the game of football.

In this Science-athon, students try to make their marble roll the farthest across a flat surface, using their knowledge of forces, motion, and energy to guide them through their apparatus design. Teachers must enroll online.

Demonstrate inertia by pushing a nickel out of the bottom of a stack without disturbing the rest of the stack.

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...

This site from The Exploratorium Museum is a full description of a short activity. An electrophorus plate and a Leyden jar are made. The electrophorus is charged by induction. Its charge is transferred to the Leyden jar by conduction...

Science experiment in which you make a hovercraft, a machine that uses compressed air to do work, from a paper cup. Includes full list of materials, procedures, and scientific explanation of how air flow can minimize friction and cause...
