Question

In order to decrease the friction an object experiences, you can either change

the surface it sits on or you can_______its weight.

Answer 1

Reduce its weight

Step-by-step explanation:

For an object on a flat surface, the maximum force of friction experienced by the object is given by:

`F = \mu W`

where

`\mu` is the coefficient of friction

W is the weight of the object

As we can see from the formula, there are two ways of reducing the friction:

- Decreasing
`\mu` --> this coefficient depends on the material and on the roughness of the surface, so this can be changed by changing the properties of the surface

- Decreasing W, the weight --> this can be done by reducing the mass of the object
