Here is the velocity-time graph of a car for 50 seconds. Work out the average acceleration during the 50 seconds. Give the units of your answer. Estimate the time during the 50 seconds when the instantaneous acceleration = the average acceleration You must show your working on the graph..... (2)..... (2) 6.
VELOCITY-TIME GRAPHS – PRACTICE QUESTIONS 1. The velocity-time graph below shows the journey of a car. 20 (a) Use the graph to estimate the speed of the car after 30 seconds. (b) Use the graph to find the acceleration of the car between 20 and 40 seconds. 2. The velocity-time graph below shows the run of a sprinter. Time (seconds)
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.
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.
Here we will learn about a speed-time graph including drawing, and reading from speed-time graphs. We will also learn about finding acceleration and distance travelled from a speed-time graph. There are also speed-time graph worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re ...
Convert the following times from hours and minutes to hours, giving your answers as mixed numbers and decimals, correct to 2 decimal places. (a) 1 hour 40 minutes (b) 3 hours 10 minutes
Velocity-time graph challenge. Draw a set of axes for a velocity-time graph in your jotter. In your neighbour’s jotter, neatly and using a ruler, draw in a simple journey involving at least two changes in acceleration.
