=III. Acceleration= = **a: shows speed vs time** = = **j: slanted line** = = **b: straight line shows acceleration is constant** = = **c: not a straight line, object's acceleration is different amount by each second** = = **d: distance v time** = = **j: curved line** = = **ii: speed increase / graph curves upward** = = **Quiz 1.3** = =Study Guide= =7. an airplane following a straight flight path= =19. True= =20. False -acceleration= =27. velocity=
 * 1) === The rate at which velocity changes constant speed. ===
 * 2) === AKA- speeding up, increasing speed, changing direction, decreasing speed ===
 * 3) === Deceleration- decreasing speed (but also called acceleration) ===
 * 4) =Circular motion - objects that change direction without changing speed=
 * 5) =Acceleration- (final velocity- initially velocity/ time) =
 * 6) =Unit of acceleration- meters/seconds/second- m/s2=
 * 7) =Object moving without changing direction, the acceleration of the object is the change in its speed during 1 unit of time.=
 * 8) =Acceleration is the same if an object's speed and direction change by the same amount during each unit of time=
