I'm sure you know that driving in your car encompasses all the basic components of kinematics: position, displacement, velocity, time, and acceleration. �V@��Td��|Y�LDz�*tǿ%j��v�*K}�H0�/,�*��@)T?��8A/�[�C~�m�����J�A� |6åh������޴6��n�$���0���'�`"��kDl�7�����ߺ���o�ݧW����K�HF�� If we set up our graph with position on the y-axis and time on the x-axis, a line on the graph that is rising represents motion away from the object's initial position. This means the object is moving forward and getting farther from its initial position. What you would end up with is a long list of numbers. Describing motion with graphs can be a simple, yet powerful tool in your physics arsenal. Get access risk-free for 30 days, %PDF-1.3 %���� Now, describe what is happening between 9 and 13 seconds.
