Graphing Motion Purpose a) Construct d stance-ime graphs from given tabulated data. b) Describe moton in words, using the graph as point of reference. o) Calculate and interpret the slopes of the graph. Materials Ruler, penci, and calculator Data Part A- Data for a Bicycle's Motion Distance Time dim) tis) 20 38 60 79 100 120 138 10 12 14 1) Plot the above tabulated data (distance, d vs. t) 2) Describe the graph. What does it show regarding the motion of the bicycle? 3) Find the slope of the graph. What does the d-t graph represent? Part B- Data for the Motion of a Passanger Joepney Distance dim) Time t(s) 50 100 100 100 150 100 50 1) Plot the distance against time (d-t graph) 2) Describe the graph. 3) Describe the motion of the car. Is the speed constant? How do you know? 4) Draw a line tangent to the curve at t75. Get the slope of the straight line drawn tangent to the curve. What does this slope represent? 5) Describe the motion of the jeepney based on the slopes you calculated in no. 4. Part C-Data for the Motion of a Car Distance dim) Time t(s) 15.5 46.5 75 105.2 150 200.1 4.8 8.7 11.1 13 15.3 17.7 1) Based on the graph, compare the motion of the 3 vehicles in the sample data. 2) How do you determine the speed of the object from its distance vs. time graph? 3) What does a straight Ine in distance vs. time graph indicate regarding the object s moton?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
