KE = kinetic energy PE = potential energy GPE = gravitational potential energy energy is always measured in Joules (J)
KE = (0.5) times the mass times the velocity^2 square the velocity first
Mass = (KE x 2) / v^2 square the velocity first, then double the kinetic energy, then divide mass is measured in kg
velocity = sqrt(KE x 2 / m) velocity can be called speed, like in the the second problem remember to find the square root after you double the KE and divide that by the mass. for example: if after you doubled KE and divided it by the mass you got sqrt(20), the answer would be about 4.47
GPE = mass x gravitational pull (about 9.8 m/s^2 on earth) x height
height = (PE) / (g x m) do g x m first
So for question 1: KE = (0.5)0.1 x 1.1^2 always square the velocity first: KE = (0.5)0.1 x 1.21 KE = 0.0605 so if you rounded it to the nearest hundreths you would get KE = 0.06 J don't forget the unit of energy is in Joules
Answer: Heat will transfer from the water to the air. When a mass of air moves on a warmer surface it is heated by its base. Then thermal instability develops in the lower layers and then extends upwards. If the air initially contained inversions, these are destroyed and a strong gradient is established uniformly in the lower troposphere temperature.
