 Things I Learned The rubber band can stretch along ways

# data[].attributes.body
Gravity and friction and how they work.

# data[].attributes.body
without friction we wouldn't be able to move

# data[].attributes.body
I learned that elastic and gravitational forces are complete opposites. In gravitational energy you want the car to be heavier, but in elastic energy, you want the car to be lighter.

Gravity and friction and how they work.

I learned that when making a roller coaster car you cannot have too much weight on the front or the car will flip.

# data[].attributes.body
I learned that the weight off the car causes how fast or slow the car gose

# data[].attributes.body
I learned that the weight or mass of an object effects the speed and distance of which that object goes.

# data[].attributes.body
more weight to things make a object faster.

# data[].attributes.body
The weight needed to make a car go faster depends on the force being used.

# data[].attributes.body
The heavier the car the easier and faster it goes on the roller coaster.

# data[].attributes.body
If you have more weight on a roller coaster car, the faster and easier it will be to continue down the track. This is because gravity is pulling it down, and the weight of the car is also helping.

Using gravity to get a car over a small hill and if you use more weight the better chance it will get over the hill.

I learned that the mouse trap cars went faster when they were light. This is because the mouse traps do not have a lot of energy compared to the Earth.

# data[].attributes.body
The heavier the car is on the rollercoaster the faster it goes because the weight is pushing once the energy is released

# data[].attributes.body
I learned that when when you have something heavier and push it down a hill to will go faster than it being lighter.

# data[].attributes.body
I learned that in order for a car to move the car needs friction to stop it's tires from spinning out. With the mouse trap cars you had to add weight to the back tires.

# data[].attributes.body
That the mouse trap put off more energy than gravity during the roller coaster.

# data[].attributes.body
I learned that when using the mouse trap cars, we wanted the car to be smaller and lighter to make it go further.

# data[].attributes.body
I learned that the weight of the vehicle causes how fast the cars goes.

# data[].attributes.body
In gravitational situations objects with more mass accelerate faster than lighter objects

# data[].attributes.body
I learned that the lighter a car is the faster it goes

# data[].attributes.body
with elastic force less weight makes the object move faster. I learned this through the mouse trap cars.

# data[].attributes.body
I learned that the weight of a vehicle can help detect how fast it might go.

# data[].attributes.body
This is a test.
