Power

Power in physics is defined as the amount of energy consumed per unit.  The units used to measure power is in Watt.  Energy transfer can be used to do work, which concludes that power is the rate of which work is performed.  Power is the rate of doing work or the rate of using energy, which are numerically the same. If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts. In this picture it shows me going up the stairs, the reason i chose this was because it relates very well to our lab that we had done recently.  It shows the power being used to go up the stairs using work.  To calculate the power precisely you must consider the factors of the height of each step, then also the amount of the stairs that i was climbing.  I would also have to consider my weight to consider the approximate amount of power.  That is most of the techniques to consider power and to find the right amount

Thanksgiving post

When we talk about what we are thankful about i think about family, friends and everything in-between , however when we talk about physics i am mainly thankful for gravity.  The reason why i feel gravity is so important first of all is because to me its like a stabilizer it keeps us on the ground and allows us not to float in the air.  When i think about gravity, the first thing that comes to my head is floating, and Newton's Theory.  In this picture this is just a picture of me jumping and landing showing the true nature of how gravity works and that you will always land.
