In this lesson, we will calculate speed from distance time-graphs. We will introduce the formula used to calculate this measure, and discuss how to interpret it.

In this video Professor Brian Cox introduces the concept of average speed and demonstrates how a distance-time graph can be used to represent a journey and calculate the average speed taken to ...
Speed at a given moment in time. Equal to the magnitude of the instantaneous velocity. Has SI units of m s . Equation. Symbol breakdown. Meaning in words. v ¯ = Δ x Δ t . v ¯ is average velocity, Δ x is displacement, and Δ t is change in time. Average velocity is displacement divided by time interval of displacement.
Distance calculator. With the distance calculator distance.to you can easily determine distances between world-wide locations. Simply enter any desired location into the search function and you will get the shortest distance (air line) between the points, the route (route planner) as well as all important information.
The time that this journey will take is worked out by using the formula 'time = distance ÷ speed', 15 ÷ 10 = 1۰5. This is 1 hour and 30 minutes. The time is now 09:00 and the distance is 0 ...
In a speed-time graph the acceleration is the gradient of the graph. Acceleration = 1.5 m/s2. b) Work out the distance covered by the car. In a speed-time graph the distance travelled is equal to the area under the graph. The graph is a trapezium so use the formula . Distance travelled = 130.5 m.
Repeat Step 4, stopping the times at the distances of 1.0 m, 1.5 m, 2.0 m, 2.5 m, and 3.0 m from the bottom of the ramp. Use your measurements of time and the displacement to make a position vs. time graph of the ball’s motion. Repeat Steps 4 through 6, with different people taking on the roles of experimenter, timer, and recorder.
