6.19.1 Friction and Spheres with Different Sizes

1. Create three spheres with different sizes and define equal velocities for them by using the function Modify/Properties/Velocity.

2. Create two spheres with an equal size and add the tag FMAS 10 to the second one.

3. Create a FRICTION method to the same level with the spheres.

4. Create a PROCESSOR method.

Play the animation and "air resistance" slows down the spheres. The bigger the sphere, the higher the friction . The higher the velocity, the higher the friction. The bigger the mass, the less the friction can change its velocity.
