  1. Simple machine lab

  2. Good Morning! • You Need: • Pencil • Science Notebook • Colored Pencils • Science Folder • Everything else needs to go to the back of the room. • Bell Work: Answer the following question in the back of your science notebook.Write the question! • Yolanda pushes a box 150m with a force of 10 N. She does this in 2 minutes. How much power did she use?

  3. Yolanda pushes a box 150m with a force of 10 N. She does this in 2 minutes. How much power did she use? • First: Write your equation • P= W/T • Second: Fill in your equation • Remember we need a time in seconds • 2 minutes * 60 seconds = 120 seconds • P= W/120 S • We are not given work but we know that w=f*d • W= 10N * 150 • W= 1500 J • Now, we can put it back into the equation • P= 1500J / 120s • P = 12.5 W

  4. Don’t forget you are working on the following learning goal: • Students will be able to apply the scientific meaning of work and predict how machines reduce the amount of work in our daily lives. • Follow the procedure on your lab worksheet. today
