On Earth, the free fall acceleration is 9.8 ft/s. 9.8m/sa At the movie theater, the film projector projects a virtual image onto the screen for us (the movie-goers) to see. Specific heat is the measure of an object's resistance to change of phase. There are 1000 cm in 1 m. l0ocm in Im A ball was thrown straight up into the air. At the top the magnitude of the acceleration of the ball was 0 m/s². In this class, when we discuss change it is always final plus initial. Momentum and angular momentum are occasionally conserved. An object will sink if its density is less than the density of the fluid it is immersed in. Two birds had a midair collision. Prior to the collision they each had 100 J of energy. After the collision, one bird had 60 J of energy and the other had 40 J of energy.
