BRTC Physical Science Class Conducts Experiments

BRTC student Fisher Francis, Instructor Justin Stewart, and student Ashley Stover

BRTC science instructor Justin Stewart used the BRTC fire tower to engage students in practical experiments and demonstrate Italian scientist Galileo Galilei鈥檚 terminal velocity, the four forces of flight, and the three laws of motion equations.

Utilizing the BRTC fire tower on the Pocahontas campus, Instructor Stewart and his students dropped various objects from the three exterior platforms to obtain measurements.听 They discussed how to use time to calculate the actual acceleration of each object and the known average acceleration to determine the heights of the platforms.听 鈥淲e were measuring total free fall time,鈥 said Stewart, 鈥渂ut using Galileo\’s equation we were able to measure the height that the objects fell.鈥

Stewart explained to students how these calculations could be used in a variety of ways in their everyday lives.听 鈥淚 actually had a student go skydiving the weekend prior to this experiment and he knew the altitude that they jumped from,鈥 said Stewart, 鈥渟o we used that information to calculate the rate at which he was falling, until he reached terminal velocity.鈥
