Speed is the bst because without it acceleration and velocity mean nothing at all.

# data[].attributes.body
I like acceleration the most because I love going faster, however, acceleration includes slowing down which can be nice sometimes too.

# data[].attributes.body
Speed is easy and I'm kinda really dumb so it helps me doing easy things.

# data[].attributes.body
Speed is my favorite because it is the easiest to calculate and is probably the most important to know.

# data[].attributes.body
The feeling of going faster and faster is just wonderful. And it is fun to see how fast things accelerate like rolar coasters and other fun things.

I like speed the best because It easiest to calculate and is very important to know how to do.

I like the feeling of speeding up and slowing down. I also have to agree with Tyler on the roller coasters. I LOVE roller coasters, when you climb up to the top, (slowing down), and go really fast.

Speed is the best. you dont have to get anything else like the others

# data[].attributes.body
I like speed the best because it easy to calculate and you need it to calculate everything else.

# data[].attributes.body
Speed is my favorite because the formula is really straightforward and it doesn't get confusing.

Speed is my favorite because it is simple and easy to calculate

i like volocity the best because it is the most accurate between speed, velocity, and acceleration and it is important to many problems

I chose speed becuase It is was easier to calculate the Acceleration and it is cool to see how fast your object is going.

I'd have to say speed. Not only is it very necessary to know average speed in real life, but it is easy to calculate. While velocity requires a known direction and acceleration takes multiple steps, speed is quick and convenient. It's also the basis of velocity and acceleration. Without speed, you can't find either of those things.

I'll have to go with acceleration because like Tyler said where would roller coasters be without acceleration? I love the Adrenalin boost when you go downwards. My dad went skydiving a few weeks ago and he had the time of his life he said. He really looked like he had fun in the video they took of him.

speed is my favorite because it's what velocity and acceleration need in their formulas to be calculated, and speed is easier to calculate and understand

# data[].attributes.body
Speed is my favorite because it is the root of velocity and acceleration, meaning that without speed there is nothing else.

# data[].attributes.body
I've got to go with speed! It's very easy to calculate and easy to get the variables. (time and distance) Velocity isn't bad but without a compass I have no clue where something is facing. Accelaration you need to calculate the speed to get it in most cases, it's just more steps. Thats why I prefer speed.

It's what make roller coasters so much fun! The feeling of turning and leaving your stomach behind on a roller coaster is because you're accelerating so fast. SO MUCH FUN! I also want to go skydiving, but that would be more speed.

My favorite calculation of movement is acceleration. This is because realistically, very little calculations in the real world will have constant speed. Objects are always accelerating and deaccelerating, and that's what Newton Physics are all about. Speed is really only useful when you are measuring something theoretical, and velocity is pretty much only used in the military. Acceleration is definitely the most important type of speed to know.

# data[].attributes.body
Speed is my favorite because both velocity and acceleration need speed to be calculated. Velocity is just speed with a direction, and acceleration is a change in speed over time. There would be no velocity or acceleration without speed, so speed is my favorite.

# data[].attributes.body
Because it is easy to calculate like speed but with the additional factor of direction tossed in.

# data[].attributes.body
Speed is simple and easy to calculate. In a lab it is also the easiest to measure. I am also more familiar with speed in everyday life.

# data[].attributes.body
Speed is my favorite because its the easiest one to calculate to me. I hate calculating accerleration.

# data[].attributes.body
Speed is my favorite because it's simple, and I hate velocity and acceleration so I have no other option.

# data[].attributes.body
Velocity is my favorite because it is more explanatory and it is simple to solve.

# data[].attributes.body
I like it because its simple, easy and really fun so see how fast you can push an object

Speed is my favorite because it is the easiest for me to calculate.
