Physics is a subject that can be difficult for students to understand. With complex equations and situations, students often struggle to visualize what the problem actually means. Experiments and activities are an excellent way for students to create a simulation of what the problem looks like in real life. Not only do experiments and activities help students better understand the situation, but also create an interactive way to engage students.
