U2 Physics

This simple lab allows the students to practice on the concept of work and power using their own body. Students will calculate the work done when lifting a 500g metal cylinder several times. Students will collect and graph data and determine the power of their hand by determining the slope of the line in the Work vs. time graph.Students then will use the information from the data and the graph to calculate the number of repetitions needed to use the energy equivalent to a hot dog.

Students add vectors using the head to tail method to determine the velocity of an airplane in reference to the ground. The velocity of the airplane in reference to the air, and the wind's velocity is given. Teachers may ask the students to work in groups and build their own arrows from cardboard and straws, draw the airplane and the angles in sticky notes and combine them to get the different situations presented, or new combinations. Every segment is one inch long.
