Interactive simulation on graphing 2nd degree polynomials (aka, quadratics). Nicely shows what each coefficient contributes. Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms (e.g. y=bx ) to see how they add to generate the polynomial curve. Especially good for constant acceleration problems in physics. These produce 2nd degree polynomials of distance vs time.

Downloadable simulation that lets you see how a second degree polynomial (aka, quadratic) changes shape when you change the coefficients. Get a good feel for how the graph changes. This Demonstration will also let you see where the zeros of the polynomial are. Good experience for constant acceleration problems. The zero is when a body in free fall, say, crosses the origin of your coordinate system.

Downloadable simulation that lets you get a feel for how a second degree polynomial (aka, quadratic) changes shape when you fiddle with its coefficients. Adjust the coefficients of the parabola to hit all of the dots. Then, click the button to get a new set of dots. Good for constant acceleration problems, since distance vs. time is a quadratic for this situation.

Interactive game: Manipulate thrust, get acceleration and velocity just right to avoid a crash. Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Interactive simulation of simple 1-D motion under gravity, normal, friction, and an applied force. 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)

Interactive simulation of how position, velocity, and acceleration graphs are made. Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion. Set the position, velocity, or acceleration and let the simulation move the man for you.
