[Free Registration/Login may be required to access all resource tools.] How to calculate acceleration from force and mass, and force from mass and acceleration.

This University of Minnesota site provides a series of contextually rich, real-world problems demonstrating force and Newton's second law of motion.

This study guide on gravitation covers some key vocabulary, Kepler's Laws of Planetary Motion, and orbiting bodies or satellites. Includes important equations. It is available for download with free registration.

This digital textbook covers core physical science concepts and includes interactive features, real world examples, and videos.

Learn about the Magnus Effect, a phenomenon discovered by Isaac Newton. Brazilian football player Roberto Carlos used it to score a seemingly impossible goal in a game of football in 1997. Includes a video, multiple-choice and open-ended...

In this physics tutorial, the law of momentum conservation will be combined with the use of a momentum table and some algebra skills to solve problems involving collisions occurring in isolated systems.

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

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...

[Free Registration/Login Required] An informational text explaining how the laws of motion apply to basketball. A question sheet is available to help students build skills in reading comprehension.

Provides a long list of physics formulas for easy reference.

Combined with aspects of circular motion, students discover that Kepler's third law follows directly from the law of universal gravitation. This unit will expand upon the conservation of energy principle for problems beyond the confines...

[Free Registration/Login Required] Learn about projectile motion and its relevance to the shape of a stream of water.

Intended for students with a strong math and science background, a course introducing physics concepts of Newtonian mechanics, special relativity, gravitation, thermodynamics, and waves. Twenty-four class sessions in video format are...

[Free Registration/Login Required] Practice with the concepts of conservation of momentum and energy by analyzing a special case of the ballistic pendulum.

The wind blowing over your house, the Gulf Stream flowing into the North Atlantic Ocean from Florida to Europe, the jet stream at 10 km altitude. All these different flows in the atmosphere and in the ocean can be understood using ideas...

Experience the effect of friction, air resistance, and applied force upon a sledder. The speed, acceleration, and force values are displayed as the sled moves. Learners can vary the mass of the sledder and the size of the parachute...

The purpose of this activity is to demonstrate Newton's 3rd Law of Motion, which is the physical law that governs thrust in aircraft. The students will do several activities that show that for every action there is an equal and opposite...

In this simulation, students pretend to launch bananas from a canon to the monkeys at the zoo. The monkeys sometimes let go of the branch at the exact moment the banana is launched. So the students must determine the correct aim angle...

[Free Registration/Login may be required to access all resource tools.] Explains inertia and how it affects motion, the relationship between inertia and mass, and how to overcome inertia.

By the end of this section, you will be able to understand the definition of force.

Through interactive illustrations and practice problems, students study Newton's Universal Law of Gravitation.

This site from NASA provides an excellent tutorial on vectors and their use in physics to describe the motion of objects. Vector addition and resolution are illustrated.

If every action has an equal and opposite reaction, what kind of physical action would it take for the earth to notice us? Check out Vsauce's video on what would happen if everyone on Earth got together and jumped. [7:13]
