Forces in 1 Dimension
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. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Teaching Resources
Main Topics
- Force
- Position
- Velocity
- Acceleration
Sample Learning Goals
- Predict, qualitatively, how an external force will affect the speed and direction of an object's motion.
- Explain the effects with the help of a free body diagram.
- Use free body diagrams to draw position, velocity, acceleration and force graphs and vice versa.
- Explain how the graphs relate to one another.
- Given a scenario or a graph, sketch all four graphs.
