constant speed
Example : A block on a rough horizontal
surface is moving to the left with constant speed
under two horizontal forces 2 N and 12 N
indicated as shown. If the force of 12 N is
suddenly removed, what is the net force acting
on the block at that instant ?
Students need to deal with force diagrams in
analysing problems

Example
Two particles P and Q start from the same position and travel along the
same straight line. The figure shows the velocity-time (v-t) graph for P and
Q. Which of the following descriptions about their motion is/are correct ?
(1)At t = 1 s, P changes its direction of motion.
(2)At t = 2 s, the separation between P and Q is 4 m.
(3)At t = 4 s, P and Q meet each other. v /m s−1
