Work and Levers: Analyzing See-Saw Dynamics with Marvin, Brainy Pete, and Jimmy Neutron

In this educational exercise, we explore the concept of work and levers using a see-saw scenario involving Marvin, Brainy Pete, and Jimmy Neutron. By calculating the work done on each side of the see-saw based on the forces and distances involved, students can visualize how different weights affect balance and height. We determine the work done when Marvin and Jimmy sit on opposing sides, and again with Brainy Pete. Students are encouraged to draw a diagram that accurately depicts the positions, labels the work done, and places the fulcrum correctly.

  1. Marvin 5N Brainy Pete 10N Jimmy Neutron 6N 3 m 5 m Work and Levers Who do you think will be higher in the air when Marvin sits on the left hand side of the see saw and Jimmy Neutron sits on the right hand side of the see saw. ______________

  2. Marvin 5N Jimmy Neutron 6N 3 m 5 m Calculate how much work is done on each side of the see saw. Right Side W = f x d W = 6N x 3m W= 18 joules Left Side W = f x d W = 5N x 5m W = 25 joules

  3. Right Side W= 18 joules Left Side W = 25 joules Draw a picture showing what the see saw will look like. Make sure that the fulcrum is located in the correct location. Label the work on each side.

  5. Brainy Pete 10N Jimmy Neutron 6N 3 m 5 m Calculate how much work is done on each side of the see saw. Right Side W = f x d W = 10N x 3m W= 30 joules Left Side W = f x d W = 6N x 5m W = 30 joules

  6. Right Side W= 30 joules Left Side W = 30 joules Draw a picture showing what the see saw will look like. Make sure that the fulcrum is located in the correct location. Label the work on each side.
