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.

Practice on solving problems related to conservation of linear momentum for inelastic and elastic collisions, and practice on determining the impulse, and final velocity of a ball bouncing off a wall

Students will practice on adding the following force vectors using the components method, graphically and analytically. Students may determine the percent difference between the numerical results to compare the values. Teachers may give extra credit to students with e percent difference less than 2%, or so. Students may work on this activity in groups to make it more competitive. This activity is target to students in Pre AP Physics or AP Physics class.
