In the following interactive students will begin to define nonconservative forces and explain how they affect mechanical energy. They will show how the principle of conservation of energy can be applied by treating the conservative...

Videos that accompany activities that are hands-on challenges that focus on the engineering design process. They use simple materials, allow for multiple solutions, and are ideal for ages 9-12.

This lesson focuses on forces and elasticity. Forces are responsible for changing the motion of objects. If more than one force is present, the shape of an object can also be changed. A link to a test is provided.

This tutorial investigates the motion of a mass on a spring and how a variety of quantities change over the course of time. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Take the...

This tutorial investigates pendulum motion and how a variety of quantities change over the course of time. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Take the interactive...

See how motion is converted and the energy associated with the motion is used to do work.

Kids learn about glossary and terms in the science of physics and motion. Definitions for words such as momentum, force, work, energy, gravity, scalar, vector, power, and more.

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

A lesson where students construct a roller coaster and test it under different conditions to learn about force and motion.

In the following interactive students will begin to explain how an object must be displaced for a force on it to do work. They will also explain how relative directions of force and displacement determine whether the work done is...

This activity is based on the common experiment of running a marble down a ramp to do work on a cup. Learners will be able to see the relationship between mass and energy of the marble and the ramp height.

Using marbles to construct a marble run, students will learn about projectile motion, kinetic energy, potential energy, final velocity, and forces.

Fantastic variety of printable activities that cover motion-related principles. Topics include the following: experiments (engineering, structures, forces and energy, fluids, sound and light, patterns, human body); arts & crafts;...

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.

Through interactive practice problems and illustrated examples, students explore energy relationships for satellites.

Through illustrated examples and practice problems, students apply the relationship between work and mechanical energy change to a variety of motion scenarios in order to test our understanding.

An interactive playground for students to explore the physics of roller coasters. Learners investigate by changing the variables of force, velocity, friction, and vectors. Energy bar charts are displayed as the coaster car moves along...

Examine the link between molecular motion and energy. Observe the movement of a molecule at room temperature. Learn about the different types of molecular motion.

Physiclips thoroughly presents mechanics concepts with animations and film clips.

Students conduct an experiment to determine the relationship between the speed of a wooden toy car at the bottom of an incline and the height at which it is released. They observe how the photogate-based speedometer instrument "clocks"...

This instructional activity is for 9th grade physical science learners. It begins with an inquiry-based instructional activity using a projectile motion computer simulation. It culminates with students building a catapult; applying and...
