A couple of days ago I fell down the stairs and even you think you cant find any physics in falling down the stairs then you would be very wrong! You could calculate the velocity at which I hit the stairs which must have been fast because I have a huge bruise on my elbow. You could also find out the force in which I hit the stairs. obviously I fell with an acceleration of 9.81m/s^2 because that is the rate at which objects fall on earth here. That darn gravity made me fall, if there was no gravity at the instant I fell then I would have just floated up to the ceiling. Their is physics everywhere and in everything you do... Remember that because it could help you in the long run!!!
