Why does friction increase as speed INCREASES?

Please explain using the big idea of particles

Answer :

According to the particle theory, the third theory is that if heated,the particles move faster and then the kinetic energy increases.I think your question relates to fluid friction and it will only increase when an object increases in which will cause it to come intact with more particles.The faster the object moves- The more particles.The greater the attraction between particles or molecules, then the greater the resistance of the molecules to flow past one another.Hope that helped !

Explanation:

Frictional force is an opposing force or a drag force. It is given by :

[tex]F=\mu N[/tex]

Where

μ is the coefficient of friction

N is the normal force

We know that the product of mass and the acceleration is called the force acting on the object. This means as the speed of the object increases, its drag force increases exponentially.

When the speed of an object increases, the attraction between the particles increases. Hence, the frictional drag increases.
