Robot Gears

A nine-page physics resource supports your lesson on acceleration. A step-by-step lesson plan walks you through the materials you need, the background information, steps for leading experimentation, and the explanation of the results....

By hanging a meter stick from a ring stand, a physics class can explore torque. Detailed procedures are listed for having learners work backwards with two and three weights and then forward with two and three weights. In each situation,...

Here are nine motion problems for physics fanatics to solve. Topics are pretty typical: rifles firing bullets, freight train cars colliding, astronauts gliding through space, balls being thrown. Pupils compute recoil speed, combined...

Introduce your young scholars to the concepts of circular motion, projectile motion, angular speed, simple harmonic motion, torque, center of mass, centripetal force, and Hooke's Law with a 86-slide presentation. The circular motion...

You may not realize it, but you get pushed around every day. What forces are acting upon you? Young physicists explore gravitational force and normal force in a video that demonstrates both forces and their directions as they move...

The magnets on a refrigerator are stronger than Earth's magnetic force. Watch a video that describes the fundamental force of magnetism. It relates magnetism to electricity and connects this to almost every type of electricity generator...

Sometimes simple machines don't seem so...simple. The video lesson explains the principles of simple machines. Viewers also discover the concept of mechanical advantage and how it affects the forces related to simple machines. 

Make your unit on magnetism a force to be reckoned with! Physical science scholars examine the direction of force on charged objects through a simple interactive. Pupils control the charge of the stationary object, then observe how it...

Students discuss that the conservatin of energy states that the energy imput must equal the energy output. They then figure out how can a machine help you to perform task otherwise considered impossible? Students discuss the six simple...

Show your students how to make their work easier. The first lesson in a series of 10 introduces the class to work and the way simple machines can be make work easier. The simple machines scholars can find in everyday items are inclined...
