Spark Timer with Constant Velocity Car

(# 632-8) Spark Timer

The Spark Timer offers high performance in a compact design. This versatile instrument works well in a vertical position for falling-body experiments. The recording needle is immediately raised when the timer is turned off to allow easy insertion or removal of tape. Two settings (10 and 60Hz) provide clear printed results to appear, even for relatively slow moving dynamic carts. The needle pressure is adjustable for increased accuracy. The blinking LED and sound signal indicates that the timer is on. A rubber padded clamp and one roll of spark tape are included.

(#633-75) Constant Velocity Car

Have fun and learn with the Sand Dune Buggy.

Many kinematic experiments require objects to move at a constant velocity. However, keeping an object from speeding up or slowing down can be very difficult and can lead to errors in data. The Constant Velocity Car can effectively hold a uniform speed which is ideal for kinematic experiments. The Constant Velocity Car can be set to travel at two different speeds by changing the batteries in the motor. The car can use either 2 C batteries, 2 AA batteries or 1 C battery in combination with a jumper. Students will be enthusiastic to learn about the concepts of motion and can easily quantify data while using this neat car. Batteries not included. Jumper included.

Car Dimensions (without windshield & antenna): 6.75 inch (175mm) L x 3.75 inch (90mm) W x 2.75 inch (70mm) H
