Answer 1

$\huge{ \colorbox{yellow}{ \color{black}{Answer}}}$

Simple Answer:

• Pressure

Detail Answer:

• Pressure is defined as force per unit area. The standard unit for pressure is the Pascal, which is a Newton per square meter.

• For an object sitting on a surface, the force pressing on the surface is the weight of the object, but in different orientations it might have a different area in contact with the surface and therefore exert a different pressure.

Formula:

$\huge \tt\boxed{P=\frac{F}{A}}$

Answer 2

Explanation:

(d) friction is a correct answer
