Potential Energy
Kinetic Energy
Kinetic Energy: energy of motion
At the beginning when the measuring tape is not moving, that is PE but when it falls the PE transitions to KE, so when the measuring tape is about to hit the ground there is no more PE only 100% KE In this case we are solving for the velocity KE=1/2mv^2 M=mass (kg) V=velocity (m/s^2) KE=1/2 x .19 x v^3
M=.19kg V=?KE turns into 1.938j 1.938j=.095v^2 -------.095------- Isolate the variables by dividing .095 by itself cancelling each other then 1.938j √20.4m/s=v^2 |

Force=ma
Measured in Newtons Work=fd Measured in Joules F=force D=distance M=mass A=acceleration |
Force=.19kg x 20.4^2m/s
M=.19kg A=20.4^2m/s Force=79.0704n Work=79.0704n x 2m D=2m Work=158.1408j |
Power=w/t
Measured in Watts W=work T=time |
Power=158.1408j/1,200s
W=158.1408j T=20m -> 1,200 Power=0.131784w |
Energy Conversion
While doing the mosaics I was sitting down pasting the tiles on the wood keeping me in Potential energy. Then when I am finished with pasting the glass tiles in my part I move to another section of the mosaic to finish it making it Kinetic energy.
