Description:
Use the Time of Flight Pad to precisely measure how long a projectile has been in motion. The Time of Flight Pad is used with the Vernier Projectile Launcher and a Vernier interface to determine the launch speed of a projectile, along with the time the projectile is in flight. Time-of-flight measurements allow students to see just how kinematic calculations work in real-world applications. The Time of Flight Pad is electrically like a photogate. When a ball strikes the foam top surface, a circuit is closed.

Catalog Number:
(470157-238)
Description:
This product is a model of a differential. This model permits the instructor and student to manually turn the handle and apply a load to the transparent wheels to demonstrate the differential mechanism.
In automotive mechanics, the differential gear arrangement permits power from the engine to be transmitted to a pair of driving wheels, which divides the force equally between them and permits them to follow paths of different lengths, as when turning a corner or crossing an uneven road. On a straight road, the wheels rotate at the same speed. When turning a corner, the outside wheel has farther to go and will turn faster than the inner wheel if unrestrained. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply.
Description:
