Zakai was tapping the table in Science class, and his teacher responded.
Teacher: Stop tapping the table! You’re deforming it!
Zakai: I am not! There’s no way that tapping a table can deform it, bro!
Does a table deform when you tap it?
Yes! EVERYTHING deforms with ANY amount of force. You just might not be able to see it.

What is the original mascot for Boston Latin Academy?
the Jabberwock
200
A material's ability to change it's shape (bend, stretch, etc.) when a force is applied and return to its original form after the force is removed.
Elastic Limit

A car travels down the highway at 60mph. A rock collides with the windshield after getting kicked up by a truck. Which object (the car or the rock) experience the most force?
BOTH experience an equal and opposite force.
200
As the mass and speed of an object increase, so to does the amount of ______________ it has generating a greater force.
kinetic energy
200
The following design matrix uses a "star" system. More stars mean that material is better at that task/ability.
Using the design matrix, which material seems to reduce force the best?
Cotton/urethane

What is Jesse the "Yodeling Cowgirl's" horse's name from Toy Story series?
Bullseye

Once a material exceeds its elastic limit, it reaches its ______________ when even after a force is removed, it is permanently deformed.
breaking point
300
A cart moving down a track will slow down and eventually come to a stop as the cart looses kinetic energy due to air resistance as it travels through the air and _________________ as the wheels roll down the track.
Friction
300
As we double the mass of an object, the amount of kinetic energy that object has _________________.
doubles

The following design matrix uses a "star" system. More stars mean that material is better at that task/ability.
Which material contributes the least to climate change?
wood
300
What country is argued to be the birthplace of the hamburger?
United States of America

When a material has structures such as ______________ that structure can deform more which absorbs more energy, reducing the overall force transferred through that material.
air pockets
400
A motorcycle and a box delivery truck are traveling from Boston to New York City. Which vehicle will use more fuel to make the trip and why?
The box truck will use more fuel becsaue it has more surface area, experiencing more air resistance, which will require more energy (fuel) to make the trip.
400
Which graph accurately represents the relationship between speed and kinetic energy?
Graph 3
