5.6.2 Distance-time and displacement-time graphs. Distance is a scalar quantity and is a measure of how far something has moved. One example is the milometer in a car. This shows how far the car has travelled, but not in which direction. Displacement is a vector quantity and tells us the distance something has. videos.
Getting Displacement from Velocity-Time Graphs Graphs can be very useful in understanding the motion of an object. We have already established that the graph of the displacement of a person travelling at a constant velocity vs. time is a straight line.
distance–time graph. Measuring speed using a motion sensor The motion sensor (Figure 1.6) transmits regular pulses of ultrasound at the trolley. It detects the reflected waves and determines the time they took for the trip to the trolley and back. From this, the computer can deduce the distance to the trolley from the motion sensor.
The distance-time graph below shows her journey. (a) How long was the meeting? (b) What time did Grace leave the meeting? (c) How far from home was Grace at 15:15? (d) How many miles did Grace travel between 07:00 and 08:30? (e) Work out Grace’s average speed on the journey from Bristol to London.
Speed, Distance & Time Calculator. Use this speed calculator to easily calculate the average speed, distance travelled and the trip duration of a vehicle: car, bus, train, bike, motorcycle, plane etc. Works with miles, feet, kilometers, meters, etc..
How to read a position vs. time graph. Using the graph to determine displacement, distance, average velocity, average speed, instantaneous velocity, and instantaneous speed. Created by David SantoPietro.
You can use the calculator below to summarize traveled distance: Distance traveled: 14100 (m, ft, km, miles - depending on the units used) Example. A car travels intervals with constant speed: 25 m/s in 120 s. 30 m/s in 220 s. 15 m/s in 300 s. The total distance traveled by the car can be calculated as.
