Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.
Physics 20d-t & v-t Graph WorksheetThe following questions involve the interpretation of d-. (aka position-time) and v-t graphs. As you work through them, make sure that you keep in mind that different types of graphs show. fundamentally different information. Besides reviewing.
Lesson 9: d-t & v-t Graphs. Graphing the motion of objects gives us a way to interpret the motion that would otherwise be difficult. Graphs will also allow you to show a large amount of information in a compact way. Sometimes called d-t graphs, or position – time graphs. Sometimes called v-t graphs.
The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.
1. The velocity-time graph below shows the journey of a car. (a) Use the graph to estimate the speed of the car after 30 seconds. n . 2. The velocity-time graph below shows the run of a sprinter. (a) Use the graph to find the sprinter’s acceleration between 0 and 20 seconds. (b) Use the graph to estimate the sprinter’s speed after 8 seconds.
Velocity-Time Graphs – Key things to remember: With speed on the y -axis and time on the x -axis, a speed-time graph tells us how someone/something’s speed has changed over a period of time. 1) The gradient of the line = Acceleration. 2) Negative gradient = Deceleration.
For each v vs t graph: describe the motion in detail and draw the corresponding d vs t graph 5. In the following v vs t graph where each square is 1.0 seconds on the time axis, and v is in m/s
