From a chapter on Statics and Torque in a Physics textbook. This section of the chapter provides an in-depth discussion of forces and torque in the human body. We learn about muscular force, the importance of posture in preventing back...

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat. It works because of something called centripetal force and it does much more than make a great roller coaster. In this...

In the following interactive students will begin to explain work as a transfer of energy and net work as the work done by the net force. They will also explain and apply the work-energy theorem.

This guide focuses on four physical science topics that fascinate children and scientists alike. They are motion, magnets, sound, and light. With your guidance and support, these topics provide children with many opportunities to explore...

Describes the definition and relationships between force, work and power. Includes nice drawings to increase conceptual understanding.

Investigating a waterwheel illustrates to young scholars the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some...

In the following interactive students will define conservative force, potential energy, and mechanical energy. They will explain the potential energy of a spring in terms of its compression when Hooke's Law applies. Students will also...

Through interactive practice problems and examples, students calculate the amount of work done by forces.

This site is from the Physics Department at Georgia State University. The conservation of energy as a fundamental conservation law is presented and compared to other conservation laws (momentum and angular momentum). Links to further...

The orbits of satellites are described and an energy analysis is performed. Kinetic, potential and total mechanical energy are explained and applied to the motion of satellites.

For this lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. Already encountering simple machines everyday, students will be alerted to their widespread...

Help the Mummy build a rollercoaster to entertain the Atoms Family monsters by investigating the concepts of kinetic and potential energy.
