Do you need to review any of Newton's three laws? This website contains a video collection on Newton's Law from a physics course at East Los Angeles College. In twelve lectures, each law is explained with examples. Also discussed is...

Observe how friction affects a mass connected to two springs that are on opposite sides of the mass. Create a graph while the friction is on or off.

This site is a discussion and animation about whether the total mechanical energy of a cart rolling down an incline is conserved, which can be determined if there are any external forces acting upon it.

A contrast of Galileo and Aristotle's view of inertia and motion. Describes air resistance force and how its reality seems to initially support Aristotle's view.

Take this ten question multiple choice quiz on motion and mechanics.

A detailed look at the aerodynamic principles associated with cycling. Good science and even better web page design. Includes an online calculator that allows the user to calculate the aerodynamic drag and propulsive power of a bicyclist...

A webpage with equations and examples of how to solve inclined planes problems. Learn how to deal with slopes when surfaces usually aren't perfectly horizontal.

This resource provides a brief overview of friction. Its' affects on solids, liquids and gases is described with diagrams. An explanation of how friction is measured is included in the discussion. An online quiz can be used to check your...

This study guide on Newton's Laws covers key terms, the three laws, free body diagrams, friction coefficients and tension. Includes equations and an example problem with solution. It is available for download with free registration.

Students work in teams to investigate how aerospace engineering relates to sports, especially golf ball design and the physics of bounce. They use this information to determine whether these aerospace principles can be applied to...

Activity investigates the concept of how bicycle brakes use force and friction to stop or slow mechanical motion. Students work in teams to devise a simple braking system while suggesting improvements to current bicycle brake design.

Here is a simulation demonstrating an object placed on an inclined plane. The user will vary the slope of the plane to see the relationship the slope has on the gravity of the object and the static friction.

Students will create a gravity ball launcher to demonstrate their understanding of mass, force, momentum, and motion. The students will use critical thinking, measurement, and observation and analysis of data to make changes and improve...

A short biography about Charles Coulomb, known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion.

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

Students will drop and shoot horizontally "Nerf" balls from a variety of known heights then record the amount of time it takes for the ball to hit the ground for each trial. They will plot height vs. time data and create a trend line for...

In this hands-on activity students learn about the laws of physics by creating a marble roller coaster.

A teacher lesson plan which includes activities pertaining to common methods of charging objects - induction, conduction, and friction.

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...

An easy to do activity that investigates the basic theories of inertia. The activity is in lesson plan format that meets NSES standards.

Watch how the placement of two weights attached to a chain on different sides of a pulley affect the movement of the system. You can adjust the heaviness of the weights.

Animation of the single-block "Earthquake Machine" model shows how "Forces, Faults, and Friction" interact. [0:16]

Students must determine the force of friction on a car on a turn and the maximum speed the car could navigate a turn.

This lesson focuses on electric charges. Electric current is the flow of electric charge. Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged,...
