Newton's Laws

Free Body Diagram Activity:
Before plunging into solving problems with Newton's Laws, practice your skill in constructing free-body diagrams.

Issac Newton's first law of motion:
Apply different forces on the box and observe its motion. (Scroll down and click on "Newton's first law demonstration". VRML required.)

Newton's Cradle:
Adjust the number of moving balls and observe the conservation of energy shown through the balls' movements.

Pulling a block horizontally:
Adjust the mass and the pulling force to calculate the acceleration.

Fan cart physics:
Explore Newton's first and second laws by turning on the fans so that the cart moves and by looking at its motion.

Forces and Newton's Laws of Motion:
Click on #4 simulation to view the lesson. Adjust the amount of force each person exerts on the car and observe the car's motion.

Newton's Second Law Experiment:
Examine motion on a frictionless and on a rough pathway for an object accelerated by a hanging weight. The mass of the wagon, the value of the hanging mass and the coefficient of friction can be changed.

Bumper Car Collisions:
Newton's second and third laws come into play on the bumper cars. It is Newton's third law that causes the feeling of a jolt when you collide into another bumper car. Predict the outcome of bumper car collisions that are affected by Newton's Laws.

Force in 1-Dimension:
Explore the forces at work when you try to push different things. Observe the free body diagram on the side that shows the applied force and resulting friction force. Different things can be chosen to apply the force to and gravity of the planet can be chosen as well.
