The bob (weight) at the end of a pendulum has a mass of 0.3 kilograms. the bob is pulled to position b and allowed to swing. it goes all the way to position c and swings back. the potential energy of the bob at position b is joules. if the maximum height of the bob is 0.45 meters when it swings back, joules of energy was transformed to thermal energy. use g = 9.8 m/s2 and pe = m × g × h.

The gravitational potential energy (GPE),is the energy of position given by GPE=mgh

Where m=mass in kilogram, g=acceleration due to gravity, h=height in meters

GPE=0.3×9.8×0.45=1.323J

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

i think if it were me i whould divide 300 dide 15
