M4. Discussion: Frictionless World
Topic
In this module, we examined the concept of friction and how itaffects everything we do. Air resistance is an important type offriction that you donâ€™t want to forget about as you prepare yourpost. Consider what the world would be like withoutfriction. For example, in a world without friction, the pitcher ina baseball game can still pitch the ball because he can push offthe pitching rubber. The pitching rubber is the rubber slab atopthe pitching mound that a pitcher uses to push off to gainvelocity. But what happens when the batter swings or when the ballhits the catcherâ€™s mitt?
Now, think of one of your favorite sports or another activityyou enjoy. How would the action of that activity be different in aworld without friction? In your initial post to the discussion,describe your activity and then respond to the following:
Describe at least three ways your activity would change iffriction were taken out of the scenario.
Does friction make it easier or harder to participate in youractivity?
What are some advantages and disadvantages that you mightencounter if there wasnâ€™t friction in our world?
Finally, be sure to respond to at least two of your peersâ€™discussion posts.

in a frictionless world when the batter hits the ball the ball would fly off and wont stop because when it is in air the air is frictionless so it would attain an unusually large arc before it hits the ground because of gravity after that it will go through infinite amount of bouncing because niter the air nor the ground exert any friction on the ball For elastic coefficient the See Answer
