You spill a bucket of soapy water on a marble floor accidentally. Would it make it easier or more difficult for you to walk on the floor? Why?

$\mathtt{\huge\star{\orange{\underline{Answer }}}}\huge\star$

Soapy marble floor reduces the friction of the surface therefore it becomes more difficult to walk on the soapy marble floor.

This happens because to move forward we need to push the ground in backward direction which become difficult if friction is less.

Explain why sportsmen use shoes with spikes.

$\mathtt{\huge\star{\orange{\underline{Answer }}}}\huge\star$

Sportsman use shoes with spikes to increase the force of friction between the shoes and the ground. The increased force of friction give them a better grip while running.

Iqbal has to push a lighter box and Seema has to push a similar heavier box on the same floor. Who will have to apply a larger force and why?

$\mathtt{\huge\star{\orange{\underline{Answer }}}}\huge\star$

Force of friction increases with the increase in the weight of the object. This is because the interlocking between the two surfaces increases with the weight and greater force is required to overcome the interlocking.

Therefore, Seema has to apply a larger force.
