On Wednesday, three students came to office hours. They had questions pertaining to energy since they just started learning it. One problem involved a cart rolling down a ramp, where you needed to find its final velocity. Another problem involved two masses connected by a string hanging over a pulley. These problems compared using kinematics and forces to using energy, and we found that in many of these cases thinking about the problem using energy is easier.
On Friday, one student from Physics II came to office hours. He had some questions about the exam they just took and LonCapa problems. They mostly involved dielectrics and finding the electric field from multiple point charges.
