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...

Introduce students to the ideas of motion and force in this hands-on lesson plan.

In this lesson, students watch a video and animations that relate Isaac Newton's three laws of motion to baseball and apply what they've learned about these laws to another sport or other real-life situation.

Review the key concepts, equations, and skills for uniform circular motion, including centripetal acceleration and the difference between linear and angular velocity.

How is the motion of an object affected by forces that act on that object? Can you predict how the motion of an object will be affected by balanced and unbalanced forces? Is there a relationship between force, mass, and acceleration? In...

In this student-paced module, students apply Newton's Laws of Motion to everyday life, calculate mathematical relationships involving force and motion using algebraic formulas, and understand the difference between mass and weight.

It's fun to go swimming. To feel the power of your body as you launch yourself into the water. But did you know that swimming isn't just about skill and athleticism? The human body consists of skin, contours, and curves. How the water...

A learning module reviewing how much force is needed to push or pull objects. Also learn about the force of gravity.

Learn about forces (push or pull), gravity, and friction in this module by training dolphins.

In this unit, students will discover the period of time of one oscillation, the frequency of oscillation, the object displacement, its velocity, and its acceleration. They will also discover how to apply the principles of conservation of...

Manipulate the mass and distance of two objects to see how these properties change the gravity force.

In this science project, you can investigate how submarines use stabilizing fins to move forward. Exploring friction and buoyant force you will get closer to understanding how these large ships function. Research resources are included...

Students learn about various forces and how they relate to everyday life in this interactive learning module.

Newton's three laws are deceptively simple, but they are the underpinning of all of physics and govern the mechanics all of your actions in everyday life. Take an in-depth look at these laws in this learning module.
