8/03/17 Jonathan Makinson 10B The Manipulation of Variables to Influence the Motion of a Marble down A Ramp Experimental Details The experiment for the group changed the height of the ramp and the surface in the ramp. Lincoln Strodl, Joel Dayus, Ben Nguyen, and Jonathan Makinson were members of this group. The experimental investigation took place on the 7th and 8th of March 2017. Abstract In this investigation, physics and motion concepts were studied. These were investigated by rolling a marble down a ramp. It was studied to investigate the down changing variables …show more content…

Introduction Some of the major physics components affecting the rolling of a marble down a ramp are velocity, acceleration, and gravity. Firstly, gravity should have constantly accelerated the marble as it rolled down the ramp (Science Buddies, 2014). To beginning rolling a marble, work must be done. The formula for work is W = fd, meaning work = force x distance. Work is when a force is applied to an object moves that object, for example, rolling the marble down the ramp (Andrew Rader Studios, 1997). The velocity of an object can be calculated through the formula v = d/t, or velocity = distance/time. Velocity is the rate at which an object changes its position (the Physics Classroom , 1996). Another important component is acceleration, the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity (the Physics Classroom, 1996). It can be found by the equation (a = vf – vi / t), or acceleration = distance – final speed / time. Newtons three laws are other important physics of motion concepts: 1. if an object is not moving, it will not start moving by itself. If an object is moving, it will not stop or change …show more content…

This fulfils the aim of the experiment which was to see what effect changing the height of the ramp had on the marbles peed. This can also be related to the formula of velocity, v = d/t, in this case, v = 40/1.099, or 36.4 metres per second per second. Possible areas that could have improved the experiment including making sure the height of the retort stand was being measured to the same place each time, the pipe was properly measured, the friction was measured, and the air was the same. Some variables, like the air pressure, could not be controlled, but other variables could be controlled. The aim was not proven in relation to the surface, were is was predicted that the marble would travel faster. This could have been a calculation error in

    This was made to gather and testing ideas. Another famous scientist named Isaac Newton, discovered the three laws of motion. The 1st law deals with “an object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed.” (studios). “The 2nd law of motion deal with the second law says that the acceleration of an object produced by a net (total) applied force is directly related to the magnitude of the force.”

    Then it changes when it starts going down. Then when going down the velocity changes and does something different. my conclusion is when the ball is going up there is two ways of velocity.

    A positive acceleration happened in three places of the Rube Goldberg machine. The first was located at the beginning when the first marbles slides down the shoe (inclined plane). Without enough force and acceleration the marble’s hit wouldn’t be enough to make the car move, too much force and acceleration the marble flies out of the shoe. The second instance is when the weight is added into the pulley system, the harder it falls into the cup going down the higher the other cup lands. The third instance is after the chain of dominoes collapse and send the marble rolling down the inclined plane.

    During we test our Atwood’s machine, we asked to control the time between two weight to touch the ground in 2 second. However, it is really difficult to have difference time in 2 seconds in the real life ever we calculate to get the true mass of weights. There are two causes that we think may affect our margin of error which is the friction and the human benchmark. The friction always is the main issue of any experiments.

    This relationship is shown using the formula Ep=mgh, where Ep ∝ m, g, h. As the ride continues, there will be multiple changes in energy, where Ep converts to Ek, and vice versa. Kinetic energy is dependent upon the mass of an object and the velocity it is travelling at.

    As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.

    At first we made a Lego clock but that didn’t work. The Legos weighed too much, also the weight distribution was uneven so the motor couldn’t move the spiral made out of legos. We redesigned the clock to be made out of styrofoam because styrofoam is extremely light compared to multiple legos built together. Redesign and final outcome- We tested our device by inserting a marble in the center of the spiral and observing how long it would take for the marble to fall out of the spiral and into a glass cup.

    I will also watch how slow the cup went. I want the cup to go down the ramp fast, but not too fast. If the cup rolls down without a problem, then I know that it was a good ramp. If the ramp rolls down to fast, then I know it was too high. If the ramp rolls down to slow or not at all I know it was too

    In a Rube Goldberg experiment you can find many different physics concepts woven into its complicated transitions and exciting outcomes. During our experiment we used Gravitational potential energy, Kinetic energy, Momentum, mechanical energy, and elastic potential energy (among other things) to make this experiment happen. Our experiment started out with a type writer’s tab bar being pushed to push a car down a ramp, the typewriter has potential energy before the key is pushed as does the car. When the tab bar is pushed the typewriter, then has applied force which will change the energy from potential to kinetic energy. The transfer of energy from the typewriter to the car will change the car’s gravitational potential energy to kinetic energy and pushes the car down the ramp.

    In addition, Newton's second law of motion states "Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration. " signifying that the more mass an object has, the more force it needs to change its velocity. A force acting on an object is always the mass of the object times its acceleration is the equation obtained from the second law that supports the other laws of motion, specifically the third law which says "For every action, there is an equal and opposite reaction."

    Since acceleration is the rate at which the velocity of an object changes in a certain amount of time. The important fact is that a force can cause a change in velocity. Velocity is a measure of how quickly an object moves or changes positions with reference to a particular direction. Then like wise a change in velocity will have a change in forces. Also we find force by multiplying mass time acceleration.
