Blogmas Day 2

For today's Blogmas, I thought it would be interesting to calculate the force inflicted upon an ornament when it falls off of a Christmas tree. I have a 7ft Christmas tree so I decided to calculate the force exerted on an 35g ornament from this height assuming the ornament is placed at the top of the tree. F=mg therefore the force of the ornament when it hits the ground is .343N. I thought it would also be interesting to calculate the power of the ornament as it is falling. Using conservation of energy, I found the velocity of the ornament to be 6.47m/s. Then using the equation P=FV I found the power to be 2.21 watts.
