Groups
This demonstration shows that two objects with different masses fall at the same rate (if we ignore air resistance). The rate of acceleration of an object is independent of the object’s mass.

Click the “drop” button to see how the time, speed, and distance change in relation to one another as the object falls. Or use the slider to control the fall and examine how each variable changes. (Note: This system assumes that the effect of air resistance is approximately negligible and that the acceleration due to Earth's gravity is approximately 10 m/s2.)
