Question

write an activity that describes effect of area of contact on frictional force​

Answer 1

Answer:

yes frictional force is a contact force.

Explanation:

friction of the body make force

more friction more force.

example: u ever observe you slipped on wet surface because water reduce friction.

if there is no friction in the world. we can't walk' vichel can not run. life will not possible. friction important role in our daly life

Answer 2

Answer:

The force due to friction is generally independent of the contact area between the two surfaces. This means that even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience the same frictional force when you drag them over the ground.
