K.C.S.E Physics Q & A - MODEL 2015PP1QN18
(a) Figure 13 shows a pendulum bob suspended by a thread moving in a horizontal circle
(i) Name two forces acting on the pendulum bob as it moves.
(ii) State what happens to each of the forces when the angular velocity of the pendulum bob is increased.
(iii) State two applications of uniform circular motion in daily life.
(b) Figure 14 shows a block floating in water.
When the water is heated; it is observed that the block sinks further. Explain this observation.
(a) (i) Tension (T)
(ii) Tension - increases
Weight - remains constant
(b) When heated the density of the water decreases hence block sinks further as it displaces more volume of water.
