Question 11 (ID=1201437) The graph below represents the motion of a bike as it moves along a straight road for 18 s. Velocity (m/s) vs. Time (s) 10 Time (s) Which statement best describes the motion of the bike over the 18 s? The bike is initially at rest and then goes backwards for 8 s. The bike has a displacement of 4 m in the first 10 s and then slows down until it stops. O The bike travels at a constant speed for 10 s and then slows down until it stops. The bike is initially at rest, and then it slows down until it stops.

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
