Question
Which of the following are the possible effects of friction on an object?It can slow the object downIt can make the object heavierIt can cause the object to heat upIt can keep the object from slipping
Solution
The possible effects of friction on an object are:
-
It can slow the object down: Friction opposes the motion of an object, thus slowing it down. This is why we need to exert force to keep an object moving.
-
It can cause the object to heat up: When two surfaces rub against each other, the friction between them generates heat. This is why your hands get warm when you rub them together.
-
It can keep the object from slipping: Friction between an object and the surface it's on can prevent the object from slipping. This is why we can walk without slipping on the ground.
The statement "It can make the object heavier" is not a possible effect of friction. Friction does not change the mass of an object, so it does not make the object heavier.
