United Scientific AdvancedGen Second Law of Motion Apparatus
Give students a vivid demonstration of the independence of horizontal and vertical motions.
The Second Law of Motion Apparatus is a classic device that projects one ball horizontally while a second is just released to fall. Both experience a vertical acceleration due to gravity, neither experiences a horizontal acceleration after release. Despite the difference in their horizontal speeds, both strike the floor simultaneously, showing that vertical and horizontal motions do not affect each other. However, if the projected ball is not launched horizontally, the two balls do not strike simultaneously.
Features:
- Included table clamp gives a stable support and is firmer than a stand rod
- Included bubble level insures accurate horizontal orientation
- Miniature magnet and series of holes on projection path guarantee accurate centering and release of projected ball
- Adjustable stop offers a wide range of spring tensions
- Easy angle adjustment allows range and time-of-flight increases with increasing angle of projection to be demonstrated quickly
- Mounting tabs allow for attachment of photogates with optional mounting bracket
