Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time.

[Free Registration/Login Required] Learn about the relationship between position, velocity, and acceleration for two objects in one-dimensional motion. Experiment with varying approaches to the race for both Irwin and Ruthie to see how...

Students watch video clips from the October Sky and Harry Potter and the Sorcerer's Stone movies to see examples of projectile motion. Then they explore the relationships between displacement, velocity and acceleration, and calculate...

[Free Registration/Login Required] This lesson explores forces, and how they react to the world around us. It also discusses Newton's Laws of Science.

[Free Registration/Login Required] Learn about adding force vectors in two dimensions using the example of a painting hanging from two strings. Experiment with variables of weight and angles to hang a portrait in this physics simulation....

[Free Registration/Login Required] Learn about the trajectories in two dimensions through simulation and examples. Some of the concepts identified are motion and velocity.

This super simple activity for kindergarten-age students requires no materials and can be done inside or outside, or both and explores forces and motion.

[Free Registration/Login Required] Learn about adding two vectors together by components in the context of a GPS-style city map. Adjust magnitude and angles in the two vectors to simulate the driverless car. Examples taking this concept...

[Free Registration/Login Required] Learn about centripetal motion in the context of the game of tether-ball.

[Free Registration/Login Required] Learn about the centripetal motion in the context of a roller coaster going through a loop-the-loop and over a hill.

Students watch video clips from October Sky and Harry Potter and the Sorcerer's Stone to learn about projectile motion. They explore the relationships between displacement, velocity and acceleration and calculate simple projectile...

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...

Explore sports science and build a ramp that will roll a ball right to the target.

Set up several ramps around the room and allow the students to explore and investigate how they work.

Students make their own ramps and test them out by sending various objects down them.

Students make two snowy hills, one steep and one gentle, to discover their effects on rolling objects.

Students experiment with different materials and objects to make a sled that will slide down the ramps.

Students explore what happens to a rolling object when the steepness of the ramp is increased.

Video that uses an elevator in motion to describe the relationship among weight, gravity, and relative motion. [3:36] Includes a short quiz and a list of additional resources to explore.

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...

Learners explore vectors, projectile motion, and forces in two-dimension. The tutorial consists of lessons and problems to check for understanding.
