U2 Physics

Use the HCSR-04 ultrasonic sensor to measure force. Led your students build their own force sensor and learn the principles of sound propagation, and reflection, hook's law, and instruments calibration. Use the sensor made to measure the force in other lab activities. Cultivate creativity, and ingenuity by letting the students make their own designs, using different materials and their own designs. Learn how to use the arduino board to collect data in the physics lab.

Determine the acceleration of a wind-up cart using the arduino uno board and the ultrasonic sensor. The acceleration is calculated from the quadratic fit on the position vs time graph, or from the slope on the velocity vs time graph.

How is the intensity of light changing with the distance for a point-like source like a light bulb, or the flash light in your cell phone? explore the inverse square low and how it can be applied to different kinds of light sources. build a simple light sensor to be used with the arduino based U2Logger or use equipment from other suppliers. there is another packet available in my TPT store U2Physics explaining how to build and use the U2Logger to make low cost measurements in science using ardu

Use the arduino uno board and the ultrasonic sensor to track the motion of a constant velocity cart.
