This solution enhances fridge movement by balancing and adjusting forces using colorful pencils to reduce friction and improve acceleration, enabling smooth rolling over surfaces. The modification proves successful in achieving constant speed and overcoming static friction challenges.

Fridge Solution By: HallieBoatright, Josh Seiden, Lauren Fitzmeyer, and Henry Menozzi
Fn= 22N Fnet= .5NW Fa= 8N Ff= 7.5N Starting to Move Fg= 22N These Forces are unbalanced because the Fnet is greater than 0 and it is accelerating because it is moving and a non-constant speed.
Fn= 22N Fnet= 0 Fa= 4.5N Ff= 4.5N Constant Speed Fg= 22N The brick is balanced because the Fnet is 0 and it is not accelerating because it is moving at a constant speed.
Our modification is a series of colored pencils, spaced out just enough so the frictionless platform that rolls over the pencils can get over without any stopping or falling over. • We eliminated the friction between the floor and the fridge by using pencils that roll easily. Modification
Fn= 22N Fnet= .5NW Fa= 1N Ff= .5N Starting to Move Fg= 22N These forces are unbalanced because the Fnet is greater than 0 and they are accelerating because the brick was just overcoming the static friction.
Fnet= 0 Fn= 22N Ff= .5N Fa= .5N Constant Speed Fg= 22N The forces are balanced because the Fnet is 0 and it is not accelerating because it is at a constant speed and the forces are balanced.
Yes, our modification was successful. We made our Fa go from 4.5N to about .1N. • The fridge rolled over 1 meter of colored pencils with ease. Was Our Modification Successful?
