K.C.S.E Physics Q & A - MODEL 2003PP1QN03

​ Figure 3 shows two identical trolleys with loads A and B. The loads are identical in shape and size.

​Given that the density of A is greater than that of B, explain why the trolley in figure 3(ii) is more suitable.

answer

• Low density / weight / mass lowers Cog Lower Cog increases stability. Or higher mass / weight / density raises Cog. Higher Cog. reduces stability.
