For the second calibration point, attach a 200 g mass to the sensor by means of a string passing over the pulley.For the first calibration point, do not apply any force to the sensor, enter 0 N, and hit Keep.You will perform a two-point calibration of the sensor: To calibrate the force sensor, select Experiment/Calibrate and select the Force sensor. Set the sensor to the ☑0 N setting and securely attach it to the top of the cart. The relationship between the force acting on an object and its subsequent motion is of central importance in many branches of physics. In this activity, you will measure both the motion of a cart using the motion detector and the force applied to the cart using the force probe. Since the force sensor is accurate enough to detect the weight of the hook, it should always be calibrated in the same orientation in which it will be used. Using these two points as reference, and assuming a linear relationship between force and voltage, any voltage reading can be converted into a force reading. Then a known force is applied and the resulting voltage recorded. First, no force is applied to the sensor and the resulting voltage is recorded. The sensor is calibrated by means of a two-point calibration. In order to convert this voltage information into force information, the sensor must be calibrated. This change in resistance results in a change in voltage. Strain gauges attached to the bar change resistance as the bar deforms. As a force is applied to the sensor, a small metal bar inside the sensor deforms. The force sensor measures force by means of a strain gauge. The sensor can only measure the force component applied parallel to its length, and forces directed away from the sensor are typically regarded as positive. The force sensor is a device that measures the amount of force applied to the hook attached to the sensor.
