Unformatted text preview: , to the right, to the left. For example, if the cart was moving to the right but slowing down, the Motion would be (+) but the Change in Motion would be (-), etc. Repeat this procedure, however, this time use a mass hanging from a spring scale (note that you can calibrate the scale for zero by turning the screw at one end so that it reads zero before it experiences any forces). Define up as (+). Note that you will be treating the mass (and not the scale) as the object. Quantity
i. at rest. A) Cart while it is
ii. moving while being tapped with pen in same direction of motion. iii. moving but pen is not in contact. iv. moving while being tapped in opposite direction of motion. B) Mass while it is
at rest. being pulled by scale. Motion Change in Motion Net Force What is your conclusion, based on the above results, about how motion (or change in motion) is related to the net force? Write it in the hand-in sheet. Activity 2 Open up "FORCE SENSOR.cmbl". Using two force sensors, design an experiment to determine the magnitudes and directions of the forces between two objects that interact with each other directly (touching or pushing or pulling or colliding). What is your conclusion? Write it in the hand-in sheet. (Note: Make sure your two sensors are set to the same range, e.g. both 10N or both 50N). If your force sensors do not register zero before they experience forces, you may have to press the Zero button near the top right of the Logger Pro window...
