How do you graph motion in physics? how do you graph motion in physics? i've seen problems state that an object is in free fall or that it was thrown upward and hits the ground, but i don't know how to graph them. if acceleration is gravity, i know that -9.8 should be in the equation somewhere, but i don't know how to incorporate that number with an initial velocity and height.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
