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.

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.

With this hands-on lesson, help learners understand force, gravity, friction, and speed. Students will also learn how each of these concepts affects the another.

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....

By the end of this section, you will be able to define nonconservative forces and explain how they affect mechanical energy, and to show how the principle of conservation of energy can be applied by treating the conservative forces in...

See how forces affect various items that are pushed or pulled.

We all recognize what friction is, but do you really understand what causes it? This project focuses on friction, its causes and forces and specifically how it affects how fast you can slip down slides.

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

In this document, we will try to answer a fundamental question of physical science, "Why do things start to move, slow down, speed up, stop moving or change direction?" In answering these core questions we can develop concepts that can...

Use this simulation to see the results of applying a force to move an object. Analyze forces and friction using graphs.

Application of Newton's Law of force and gravity to computer graphic programming.

Students are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down...

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

A video and a short quiz on acceleration.

In this investigation, learners will learn that speed, velocity, and changes in velocity are the result of the action of forces on objects such as friction. They will be able to explain how the force of friction opposes motion by...

In the first of two lessons of this curricular unit, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Student teams use spring scales to drag objects, such as a ceramic...

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....

Forces are everywhere. Learn what they are, the characteristics of forces, different kinds of forces, and factors that affect them.

An interactive tool where students can explore how a spring behaves, and how changing the elasticity, mass, push/pull force, and friction affect its motion or period. As the spring moves, its motion is shown on a distance-time graph.

In the following interactive students will begin to calculate coefficient of friction on a car tire. They will also calculate ideal speed and angle of a car on a turn.

Students use LEGO MINDSTORMS robotics to help conceptualize and understand the force of friction. Specifically, they observe how different surfaces in contact result in different frictional forces. A LEGO robot is constructed to pull a...

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

Students study how the nature of two materials in contact, and the smoothness of their surfaces affect the magnitude of the sliding force of friction. They use a force sensor to measure frictional force for different surfaces.

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.
