DistanceTime Distance Distance Distance D t D t D t Gradient speed DistanceTime graph gradient velocity Graphs Representing Motion Velocitytime graph Gradient acceleration Area . Sometimes, two graphs have exactly the same form, in the sense that there is a one-to-one correspondence between their vertex sets that preserves edges. In such a case, we say that the two graphs are . Describing the motion of an object is occasionally hard to do with words. Sometimes . graphs. help make motion easier to picture and therefore understand.. Remember:. Motion. is a change in position measured by distance and time.. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Sometimes, two graphs have exactly the same form, in the sense that there is a one-to-one correspondence between their vertex sets that preserves edges. In such a case, we say that the two graphs are . Use the units of mass, length, and time.. Define displacement, velocity, and acceleration.. Use the units of displacement, velocity, and acceleration.. Measure velocity and acceleration.. Use distance-time and velocity-time graphs.. Physics. How to interpret a . Position. vs. time Graph. Low on the graph. .. High on the graph. .. Slopes uphill.. Slopes downhill.. 0. x. t. Near. Far. Away. Toward. How to interpret a . Position. vs. time Graph. Section . 10.3. Representing Graphs: . Adjacency Lists. Definition. : An . adjacency list . can be used to represent a graph with no multiple edges by specifying the vertices that are adjacent to each vertex of the graph.. Motion graphs are an important tool used to show relationships between position, speed and time.. It’s an easy way to see how speed or position change over time. Distance vs. Time Graph. Shows an object’s position at a given time.. Nature of science: . Observations: The ideas of motion are fundamental to many areas of physics, providing a link to the consideration of forces and their implication. The kinematic equations for uniform acceleration were developed through careful observations of the natural world.. (. pg. 30-55). Do Now. Why is it important to describe and analyze motion. ?. How fast?. How far?. Slowing/Speeding?. Rest/Constant velocity. What . are some of the different types of motion. ?. Translational – motion along a straight line. September 20, 2016. What do we already know about graphing motion?. We know how to draw and interpret position vs time (P-T) graphs. Straight lines = . . Positive slope Negative slope: Zero slope: . Position. vs. time Graph. Low on the graph. .. High on the graph. .. Slopes uphill.. Slopes downhill.. 0. x. t. Near. Far. Away. Toward. How to interpret a . Position. vs. time Graph. Steep slope.. September 9-10, 2014. What do we already know about graphing motion?. We know how to draw and interpret position vs time (P-T) graphs. Straight lines = . . Positive slope Negative slope: Zero slope: . Describing motion is occasionally difficult to do with words. Graphs can help simplify this description greatly. Position = Distance from a starting point. Velocity = rate of change in position. Acceleration = rate of change in velocity.
