Kittens jump around and run alot. I'm going to track my cats movement for 7 minutes (I like the number 7 so that's why I picked that) and talk about the general physics in her energy.
12:48 - Mia is standing on the ground at first. She then jumps onto my bed, increasing her potential energy. She then further climbs up the back of my shirt, and further increases her potential energy.
12:49 - Mia returns to the bed, decreasing her potential energy from my back. She tries to get into my food. Then she runs around the bed, at a velocity of probably 2-3 m/s, meaning she has some kinetic energy while she runs.
12:50 - Mia takes a trip to the litter. I won't go into further detail.
12:51 - Since Mia is back on the floor, her potential energy is back to where it was at the beginning. She's done a lot, so she gets a quick drink.
12:52 - Mia is again running, but this time on the floor, so she has less overall energy than when she was running around on the bed.
12:53 - Mia needed food. Being a physics subject is hard work, I guess.
12:54 - Mia jumps up onto the window sill, meaning she has increased her potential energy yet again. However, the window sill is lower than my bed, so she has not done as much work as when she jumped onto the bed.
12:55 - Mia runs along the window sill, giving her kinetic energy, and jumps onto the bed from there, increasing her potential energy, and then I pick her up, so she no longer has any kinetic energy, but her potential energy is much higher.
I'd like to thank Mia for being such a cooperative test subject and thank you all for reading.
