### 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.

Modification

After the Change just enough so the frictionless platform that rolls over the pencils can get over without any stopping or falling over.

Fn just enough so the frictionless platform that rolls over the pencils can get over without any stopping or falling over.= 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 just enough so the frictionless platform that rolls over the pencils can get over without any stopping or falling over.= 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 just enough so the frictionless platform that rolls over the pencils can get over without any stopping or falling over.Fa go from 4.5N to about .1N.

• The fridge rolled over 1 meter of colored pencils with ease.

Was Our Modification Successful?
