research question:
How mass affects the distance traveled by a skateboard?

# data[].attributes.body
Personal engagement - I have always loved to train in fitness, in training, I walked a certain distance with balls in time.  One day, I wondered if mass affects time.  This experiment will help me find out how mass affects the distance I travel.  Through research, I will calculate mass and time

In liquids and gases, drag is the force that keeps bodies from moving. Drag is made up of two types of forces: tangential (tangential) friction forces that run parallel to the body's surface and pressure forces that run perpendicular to the surface. The drag force is a dissipative force that always opposes the body's velocity vector in the medium. It is a part of the total aerodynamic force, together with the lifting force.

The drag force is commonly expressed as the sum of two factors: zero-lift resistance and inductive resistance. Each component has its own dimensionless coefficient of resistance as well as a specific reliance on movement speed.

I drove from Astana to Semey, but the asphalt route was closed since we were traveling from Astana to Semey. In 9 hours, we arrived. However, when we traveled from Semey to Astana, the road was already in good condition, and we were on a smooth asphalt road. In 7 hours, we arrived.

I was into skating last summer, and I was curious about how the mass of the skater influences the distance a skateboard will travel, because I saw that when my brother pushed off with the same effort as me, he drove less.

This is why I decided to do an experiment.

I ride my bike to school and always have a large bag on my back. I'm also notorious for being late for school. But one day, I decided to undertake an experiment to ensure that the bag held the most information possible and that I could go to school fast.

Hypothesis - If the mass is greater, then the time to cover the distance will be longer.  Because Newton's second law, which says that the force F acting on a body is equal to the body's mass m.  If the mass is greater, then the time will be greater, which means that if the body is at rest, it remains at rest.  But if an object with a greater mass, then the howl will intensify, it will constantly increase, depending on the mass

How does the surface along which the body moves affect the arrival time?

# data[].attributes.body
When the body weight grows, the body speed drops; when the body weight falls, the body speed increases.

Because mass and acceleration are linked, according to Newton's Second Law, "F = ma, that is, force equals the product of mass and acceleration."

That is, the larger the mass, the less acceleration with the same amount of energy consumed.

Then, using the SUVAT formula, the acceleration is linked to the distance.

It turns out that increasing the acceleration causes the distance to grow, whereas increasing the mass causes the acceleration to drop and the distance to decrease.

If the surface of motion is changed, then the speed of the body will also change.

One of my favorite hobby is cycling. I often ride around the city on it. But unfortunately in our city there are no bicycle faces, because of what it has to ride. Otherwise you can fly on the road and get under the car. And I recently wondered if I could fly on the road, because of a different road or surface. And in this scientific study, I would like to determine the braking range on different surfaces. To prevent an accident.

mass (m) is closely related to acceleration (a) and if the body mass changes then the acceleration will increase or decrease depending on the weight of the mass
