Forces and motion
Analysis of the equation F=ma
This simulation visualizes the relationship between force, mass and acceleration.
Force in a constant mass
This simulation visualizes what happens to the acceleration and velocity when a force is applied to a constant mass.
Drag and push races
Watch these runs of two objects being dragged or pushed by a force and see what happens to the velocity and acceleration when the values of the applied force and the mass of the object are changed.
