How does physics connect to building a tiny house?
Potential Energy - Place any item at the top of something (example: a piece of wood on top of a railing ). Measure the height (in meters) from the ground to the item. Measure the mass of the tool (using the scale provided). What is the PE of the tool?
Mass of piece of wood: 0.089 Gravity: 10 m/s Height : 1.41 PE: M*G*H PE=0.089*10*1.41 PE= 1.2549 |
Kinetic Energy - Using the PE of the tool, measure the velocity of the tool as it is about to hit the ground in meters per second.
Mass of piece of wood: 0.089 PE: 1.2549 KE=1/2*MV^2 0.157=1/2*0.089V^2 0.157/0.0445=0.0445/0.0445v^2 √28.2=5.31 KE=5.31 |
Calculate how much work you do when you carry something from one place to another (example: a piece of wood, a tool, a window, a door frame, etc.).
Work= Force x Distance Force= Mass x Acceleration Work= Mass x Acceleration x Distance Mass of piece of wood:0.089 Acceleration: 10 m/s Distance:1.41 W=.222*10*1.41 W=1.2549 |
Now let's say that you have to move many of whichever item you chose from the above question in 20 minutes. How much power will you exert?
Work: 1.2549 Time= 1200 s Power= Work/Time Power=1.2549/1200=0.00104167 |
At space for art we tend to hammer a lot so hammering a nail goes from mechanical energy to deformation and heat energy
