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.

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.

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...

A video and a short quiz on Newton's Third Law of Motion. It breaks down what action and reaction mean, and how mass and acceleration factor into the outcome of a collision.

A video and a short quiz on acceleration.

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...

Conduct an investigation collaboratively on the effect of force applied on an object to produce data to serve as the basis for evidence, by using fair tests in which variables are controlled and the number of trials are considered.

[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 resource provides reproducibles that aide in student learning of force and motion. Also offers hands-on and cooperative learning activity ideas as well as an ESL/ELD activity. This resource is in PDF form; requires Adobe Reader.

In the following interactive students will begin to define normal and tension forces. They will apply Newton's laws of motion to solve problems involving a variety of forces and use trigonometric identities to resolve weight into...

Use science inquiry to predict and investigate forces and motion to help rescue Ruff's plushie from the penguins' ice rink in this sports science game.

Young scholars investigate the effects of force on objects in motion particularly as it relates to gravity and wind resistance by performing a classroom egg-drop activity.

In the following interactive students will begin to define nonconservative forces and explain how they affect mechanical energy. They will show how the principle of conservation of energy can be applied by treating the conservative...

Learn how pushes and pulls relate to theconcept of force and motion.

Three complete tutorials on vectors and two dimension forces and motion. Lessons include informational text, interactive activities, animations, and quick, interactive comprehension checks along the way.

In the following interactive students will begin to understand the four basic forces that underlie the processes in nature.

What do you think of when you hear the word motion? Are you moving right now? You may not think so, but you are. Remember, the Earth is moving around the Sun, and the Sun is moving around the Milky Way Galaxy. Everything in the universe...

A slideshow and a short quiz on simple machines and how they reduce the amount of work or effort needed to complete a task.

In this guided inquiry activity, students will use 2 marbles of different size and a box to investigate what makes the marbles move and what will cause the marbles to change speed and direction.

[Free Registration/Login may be required to access all resource tools.] Relative motion is always measured with a frame of reference. Evaluate a variety of frames of reference and inertial frames to understand relative motion.

[Free Registration/Login Required] This flipchart explains weight and gravity and engages students in activities using force and motion.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

Forces are responsible for all the interactions between particles and objects. They can be put into two categories: contact forces and non-contact forces. Forces can be added up as vectors.
