Replacement Rod, 5 inch

Photogates allow for extremely accurate timing of events within physics experiments, for studying free fall, air track collisions, pendulum periods, the speed of a rolling object, among other things. The Vernier Photogate includes an accessory rod for mounting to a ring stand. The gate has an input port so multiple gates can be connected in a daisy-chain configuration with up to four gates going to a single interface channel. The laser gate mode requires the addition of a common pen laser, which is directed into the laser port. The laser may be some distance from the gate, so that you can measure the speed of larger objects such as a rocket, model car, or even a real automobile. User manual

The Go Direct Force and Acceleration Sensor couples a 3-axis accelerometer with a stable and accurate force sensor that measures forces as small as ±0.1 N and up to ±50 N. Measure pushes and pulls in the classroom or outdoors. It directly connects wirelessly via Bluetooth® or wired via USB to your platform. The Go Direct Force and Acceleration Sensor includes a force sensor, 3-axis accelerometer, and 3-axis gyroscope. Take it on a roller coaster, swing, or slide. Suspend several Go Direct Force and Acceleration Sensors from the ceiling to perform a 3-D vector force experiment, or attach a string to the hook and whirl it in a horizontal or vertical circle. In wireless mode, your imagination is the only limiting factor! Go Direct Force and Acceleration can be used in a variety of experiments: Investigate Newton’s Third Law by connecting the hooks of two force sensors with a rubber band. Use the force sensor to pull an object across a surface to measure frictional forces. Attach the force sensor to the Centripetal Force Apparatus to measure centripetal force and acceleration simultaneously. Place sensors on Dynamics Carts to investigate forces and accelerations in collisions. Specifications: Force: ±50 N Acceleration: 3 axis, ±16 g Gyroscope: 3 axis, 2000°/s Connections: Wireless: Bluetooth Wired: USB Icluded: Go Direct Force and Acceleration Sensor Hook Bumper Nylon screw Accessory rod Micro USB Cable

Use the Dual-Range Force Sensor in a wide variety of experiments, including the study of friction, simple harmonic motion, impact in collisions, or centripetal force. The Dual-Range Force Sensor is a general-purpose sensor for measuring pushing and pulling forces. Two ranges allow you to measure forces as small as 0.01 newtons and as large as 50 newtons. It can be used in a broad range of ways: As a replacement for a hand-held spring scale Mounted horizontally on a dynamics cart to study collisions Mounted on a ring-stand to measure forces in a vertical direction Collect data from two Force Sensors simultaneously to study Newton’s Third Law ± 10 N Range Resolution: 0.01 N ± 50 N Range Resolution: 0.05 N user manual
