Our calculations and physics components
Where did we calculate and have the 10 physics components
Velocity-One place where we directly calculated velocity was in step 2 on our slideshow, where a car hit a weight and sent it off with a velocity of 0.36 m/s. We did this by multiplying the mass of the car moving towards the weight (0.625kg) and the velocity of this car (1m/s) and setting that equal to the mass(1.73kg) and velocity (unknown) of weight to get a total velocity of the weight which was 0.36.
Acceleration-On step 8, a ball rolled down a ramp. We calculated this balls acceleration by taking the velocity which was 0.66 m/s and dividing it by the time it took to go down the ramp which was 0.50 seconds to get a total acceleration of 1.32 meters per second squared.
Force-one place where the force was calculated was step 6. I wanted to measure how much force the small marble was hitting the big marble with, so I found the mass and acceleration of the small marble and got a total of 0.03 Newtons.
Potential energy-At the very start of the rube Goldberg, we calculated the cars potential energy when it started at the top of the ramp. I got a total potential energy of 7.15J
Kinetic energy-Also on the first step, the car rolls down the ramp with a kinetic energy of 0.31J because of the mass and velocity of the car.
Mechanical advantage- One spot that we calculated the mechanical advantage was on step 3. Step 3 was a pulley where we calculated the MA to be 1 because the mechanical advantage of a pulley was calculated by the amount of active pulley ropes, and we only had one pulley rope so our MA is 1.
Simple machines-We had 9 simple machines, including wedge, pulley, inclined plane, wheel and axle, lever, and a screw. We have 9 total machines because 4 of those machines were inclined planes.
