Simple Pendulum He found that a pendulum of a given length tabes always the same time to complete one oscillation. Speed = $$\frac { Distance travelled }{ Time taken }$$ There are four different types of motion shown by the different objects. A car moving on a straight road. In a Distance-Time graph, Distance is considered on the Y-axis (Vertical) and Time is considered on the X-axis (Horizontal). Speed is the rate of change of position of an object with time.The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the intervalHence, Unit of Distance is meter or Kilometer and that of time is second or hour. Scroll down for Motion and Time from NCERT Book Class 7 Science Book & important study material. Note: Galileo experimented with various pendulums to verify his observation. Examples of Rectilinear motion. Now, write time (min) on x-axis and distance (km) on the y-axis and also put arrows with them. A pendulum completes every swing or every oscillation in exactly the same time provided its length should be kept constant. Sundials water clocks and sand clocks are some examples of such devices.
