energy
Solar power is the most abundant and powerful source of energy. If the united states were one big solar panel we would collect more than enough energy to power the entire world for a few days or more in a matter of seconds. Solar energy is used for more than power it is also used to heat planets and the life on them. solar power is a non pollutant source of power so it is very useful at keeping the world alive.
speed and acceleration
rube Goldberg
we rolled a ball down a ramp witch increased the acceleration thus rising the speed.
newtons laws
when we sent down a two different balls down the same ramp at the same height there mass was different sp they moved down the ramp at different rates. they explain how things move and gain momentum and speed.
friction and gravity
the rube Goldberg showed that gravity can pull a bottle down when launched up by something of greater mass.
we used the incline plane to move a ball down to a seesaw witch hit with momentum transfering the energy into launching a bottle into a recycling bin.
