Factors that Affect the Speeds of Rollercoasters

Factors affecting the speed of the roller coaster AIM === The purpose of this survey is to investigate how selective factors affect the velocity of the roller coaster at the bottom of the slope. In the survey, I used a marble to represent a car. -------------------------------------------------------------------- -------------------- Factor ------- Vertical height of slope (high, fast) ---------- - -------------------------------------- Gradient gradation (steep, high speed) - - - -------------------------------------------- Air resistance (more, I There is a slower friction (more, lower) variable than you have

I explained several factors that affect the motion (or acceleration) of an object. Factors that affect vertical acceleration are the mass of the object, the force (speed) released, and gravity. Horizontal acceleration is only affected by mass and releasing force (applied). Gravity is of course a factor, but it is not determined by the horizontal component. But sometimes we would like to throw things like discus, hammer and so on. These bullets are influenced by force and quality, but there are other factors that affect the distance the projectile travels. In general we recognize three other factors that influence how far the elastic body moves when applying a certain force. They are:

Vectors are not the only ones that play a role in the projectile's flight and ballistics. I have speed. Both speeds are vertical and horizontal. Speed ​​is the speed at which the projectile moves in a particular direction. The speeds are completely separated from each other. (Velocity, 1991) For example, the speed at which a projectile moves horizontally does not affect the speed at which it moves vertically. In the same way, the vertical speed does not affect the distance the projectile moves horizontally. The projectile usually has a constant horizontal velocity or velocity because the moving object remains moving and there is no horizontal force. The vertical velocity will not be the same as the velocity at which the projectile moves as the projectile falls. (Initial speed, 1996-2001)

How does the projectile's initial velocity affect its range? Obviously, as shown in Figure 5 (a), the larger the initial speed 0, the wider the range. As shown in Fig. 5 (b), the initial angle θ 0 also has a large influence on the range. For a fixed initial velocity such as the speed that can be generated with a cannon, the maximum range is obtained with θ 0 = 45 °. This applies only when air resistance is ignored. Given the air resistance, the maximum angle is about 38 °. Interestingly, at each initial angle other than 45 ° there are two angles giving the same range - the sum of these angles is 90 °. This range also depends on the value of the gravitational acceleration g. As the lunar astronaut Alan Shepard is light in weight, you can play golf on the moon. The projectile range R on the horizontal plane is negligible
