The use of an infrared sensor as a new alternative to measure position as a function of time in
\nkinematic experiments was investigated using a microcontroller as the data acquisition and control
\ndevice. These are versatile sensors that offer advantages over typical ultrasound devices. The setup
\ndescribed in this paper enables students to develop their own experiments, promoting opportunities
\nfor learning physical concepts such as the different types of forces that can act on a body
\n(gravitational, elastic, drag, etc) and the resulting types of movements with good sensitivity
\nwithin the 4\u201330 cm range. As a proof of concept we also present the application of a prototype
\ndesigned to record the kinematics of mass-spring systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
