Leilani is practicing with a geometry tool to copy similar segments. The segments ab is dilated with a scale factor of k=2 and the center of dilation at the origin 0. She reflects this dilated line segments over y-axis then dilates the reflected line segment with a segment with a scale factor of k=1/2 and the center of a dilation at C=(5,5) to get line segment ab

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
