what kind of motions does acceleration refer to? increaseing and decreaseing speed, or cahnging directions.
how is acceleration calculated? to determine the acceleration of an object moving in a straight line, you must calculate the changing in speed per unit of time.
what graphes can be used to analyze the motion of an accelerating of object? acceleration = final speed - initail speed over time.
what is object in motion? an object is in motion if it changes position relative to a refernce point.
how do you know the an object's speed and velocity? if you know the distance an object travels in a certain amount of time, you can calculate the speed of the church object.
ahow can you graph motion? speed=distance over time
how does the theory of plates tctonics explains the movement of earths land masses? according to the theory of plates tectonics. earths landmasses have changed position over time because they are part of the plates that are slowly moving.
how fast does the earth's plates move? some plates move at a rate of several centimeters each year other move only a few millimeters per year
