A page describing rotational equilibrium and non-equilibrium situations. Includes graphics, equations, and many examples.

Manipulate variables while exploring principles and relationships related to moving in a circle at a constant speed. Students change the radius of the circle, the speed of the object, and the mass of the object and investigate the effect...

This lab was designed to have students investigate the factors that affect the acceleration of an object on a frictionless horizontal surface. The simulation will give the students position vs. time data and they will have to determine...

In this activity, students' use a force sensor and a motion detector to collect force and acceleration data for an object moving up and down hanging from a spring. They use the data to test Newton's second law, and to estimate the mass...

Use this online tool to convert measurements of acceleration, area, density, electricity, energy, force, length, mass, and other measurable properties.

Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when...

This site examines the black hole as an object in astrophysics. Delve into this comprehensive resource that covers this concept from its history, to qualitative physics, the reality of black holes, mathematical physics and more.

Conversion calculators galore! Convert just about anything from one measureable unit into another measureable unit here with over two dozen calculators. Each of the links is specific to a measureable quantity. Some examples include...

This app simulates circular movement and demonstrates how the position, speed, acceleration, and the applied force vary depending on the time. You may choose the option "slow animation" to make the movement ten times slower. You can also...

An introduction to the ideas behind the misconception and misunderstanding of why all objects accelerate at the same rate. This explanation involves the concepts of force and mass.

This site by the Illinois Institute of Technology gives a Lab activity in which students use a variety of toys to discover Newton's second law and momentum conservation. Newton's cradle, skate boards, and a toy motorcycle are incoporated...

Students are asked how acceleration, mass, momentum and velocity are involved in mountain boarding. [0:32]

A short quiz on Newton's famous laws of motion. Has ten multiple-choice questions.

For this lesson, students develop their own scientific experiment to test Newton's hypothesis that the acceleration of an object depends on the net force acting upon it and its mass. After completing their designed experiment, students...

Use this outline to find out about Newton's Laws of Motion. Use the different lesson plans covering the laws of motion to learn more.
