Our Rube Goldberg machine used several physics concepts in order to complete its simple task, which was to turn on a Roomba. One of the most prominent physics concepts within our project was gravity and/or gravitational potential energy, which could be seen in places such as the inclined planes and the hammer swinging down. Gravity was the downward-pulling force that allowed the energy to be transferred from the top level, to the Roomba on the floor. The toppling rule was another major concept…

Problem: how does the angle of trajectory effect the horizontal distance of a bottle rocket Background research: When an object is in the air and has no forces acting on it other than gravity it becomes a projectile. (Henderson, 1996) Gravity causes the projectile to accelerate toward the ground in a uniform arc like a rainbow does. this shape is known by scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles…

it had less of a slope to increase its speed, the less the slope the less speed. This also supports my claim because,the weight and mass of the marble could have also taken a toll on the abnormal speed of the marble clearing the track. This is because the lightweight foam track can only hold so much weight and mass, Also the track might have dipped because the mass of the marble coming down at that speed caused the track to give out on its structure and beyond. This shows that since the track…

~~~Science Project~~~ Experiment 1: Materials~ 2 eggs Needle Scale Bowl Marker Question? What is the difference between weight and mass, and can two objects that have the same mass be different weights? Hypothesis The difference between weight and mass is that mass is the measurement of how much matter is in an object and it will remain constant regardless of gravity. Weight is how heavy an object is depending on the gravitational pull on the object. Step 1: Zero out the scale. Step 2:…

Grant Alexander Pd#6 11 November 2016 Trebuchet Engineering A trebuchet is a machine used in medieval siege warfare for hurling large stones or other missiles. How this machine works is not to complex but is also fascinating. The object that is being shot is held in the sling, which is on a launch trough whose job is to make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down,…

It is often said that there is no such thing as a bad day on the golf course, but if you find yourself playing 18 holes when the wind is howling you might be rethinking that sentiment. If you are familiar with the nuances of big island golf, you know that in Hawaii the wind will definitely blow. There are few things more frustrating for a golfer than to see a ball fly straight off the club— and then watch the wind take it far, far off course. Waikoloa Village Golf Club in Waikoloa, HI, would…

Lab 6: Energy The intent of this lab is to show the relationships of energy to a system. For this experiment, we had a spring attached to a car, which was attached to a string that went through a rotary sensor and had a weight attached at the end. By stretching the spring, and causing the weight to drop nearer to the ground and bounce up we were able to determine: the angle of the string and rotations; the car position; height of the weight bouncing up and down; velocity; the stretch of the…

To conclude my hypothesis was completely wrong and the fastest pipe was the small plastic pipe, which I predicted would be the slowest pipe. The average time the plastic pipe took to roll down the ramp was 0.86 seconds. The time was 0.01 seconds faster than the pipe that finished second, which was the steel pipe. The small plastic pipe had the smallest inertia, which was 0.000003 and finished first. Also the small plastic pipe had the smallest rotational and kinetic energy compared to the rest…
