Kinematics graphs are great for showing how a quantity depends on time. For example, an acceleration-versus-time graph shows how acceleration depends on time. a. Based on your experience with two other kinematics graphs (position- and velocity-versus-time), describe how to plot an acceleration-versus-time graph. b. Describe how all three kinematics graphs are connected by slopes of tangent lines (derivatives). c. If a particles acceleration is positive and constant, what is the shape of the curve in each of the three kinematics graphs?
ex intos Learning Activities Last time, you have learned how to determine if an object is moving or not. For this module, you will learn how motion can be visualized or illustrated using tape charts and motion graphs. To help you get ready, perform the task below: by 1 Read and analyze the following statements and get ready to answer the questions listed below: A jeepney is moving at a rate of 45 kilometers within 0.50 hour before it stops at a red light. After 5 minutes the vehicle moves again, but this time it initially moves at a rate of 15 kilometers for 15 minutes which then increased to 35 kilometers after another 15 minutes. The jeepney then continued to move at the same speed until it reaches another stop. LAM ni of 1. 2.

Interpreting Motion Graphs Distance - Time Graphs We know velocity = distance ÷ time. We can also use motion graphs to measure velocity. Let's take a look at how to analyze and interpret these graphs. d t We can also use motion graphs to see if an object is coming towards or moving away from us. Assume you are at d=0. For each of the graphs below, label whether the object is moving away from you, towards you, or staying the same distance from you: ·K·E·N·K t Example Problem ● 1.For the motion graph to the right, what is the y-axis? 2.For the motion graph to the right, what is the x-axis? 3. How could we use this information to measure velocity? Write your thoughts: V = t Using the y-axis to measure distance, how far did the object travel? Using the x-axis to measure time, how long did it travel for? So, using our equation, v = d ÷ t, we can see that V = t 10 5 d(m) 0 15 t t (s) 30
