Friction Experiments (with accler.) |
|
 |
A card is affixed to a wooden block. The card faces the motion detector located near end of table. Felt may be included on the undersurface, when a more consistent, smother friction is desired. |
|
In the 1st
investigation, the block is not attached, but rather it is pushed and
then allowed to stop. The friction slows it, as approaches the
detector. |

In the 2nd investigation, a force is supplied via string over a pulley to a hanging weight. The total mass, is computed by ALL moving mass in the system subject to acceleration. |
