To investigate the Law of Conservation of Momentum
Research
4. Review Of Literature
Sir Isaac Newton was a 17th Century Physicist and Mathematician. Newton developed the principles of modern physics and in 1687 he published his most acclaimed work, Mathematical Principles of Natural Philosophy. This contained his famous laws of Motion.
First law: When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
Second law: F = ma. The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a, of the object.
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
The law of conservation of momentum is an application of Newton’s second and third laws.
The law of conservation of momentum states:
For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.
Trough the years there has been numerous practical experiments to demonstrate the law of conservation of momentum and the one that is probably best known is Newton’s Cradle.
From the literature researched and the equipment available it was decided to perform the experiment using marbles on a flat surface.
Based on my research it was found that the majority of sources had stayed true to the origin of the theory and is very reliable as there is correlation between them.
5. Hypothe...

... have been better than wood because of the different coefficient of friction.
However as the aim was to prove the conservation of momentum and it was done for all 4 marbles under the same conditions these played a minor role in the outcome of the experiment.
8. Conclusion
Based on the original hypothesis we can deduct that the hypothesis has been proven.
The same result was achieved within allowable variance for all four the marbles used in the experiment.
The magnitude of variation as a deviation of momentum was well within the expected results for all 4 the samples.
The variation can be ascribed to external factors like the timing of the distance travelled between the measured points.

One of the best methods for determining mass in chemistry is gravimetric analysis (Lab Handout). It is essentially using the the mass of the product to figure out the original mass that we are looking for. Thus the purpose of our experiment was to compare the final mass in our reaction to the initial mass and determine the change in mass.
The goal of this experiment is to develop a theory, which allows us to understand the motion of a marble.

Different collisions took place throughout the process of the Rube Goldberg Machine. This included Elastic and Inelastic collisions. An example of an Elastic Collision in our Rube Goldberg Machine is when the car went down the track and collided with another car. Elastic collisions are defined as collisions with conservation or no loss of momentum. This is proven by the first car which transferred its momentum to the second car thus momentum was perfectly conserved. An Inelastic Collision is seen in our project ...
This equation shows that mass will not affect the speed of an object, proving that whatever the mass of an object, the speed will always remain the same if all the other factors are kept constant.
In 1687, Newton published Philosophiae Naturalis Principia Mathematica (also known as Principia). The Principia was the “climax of Newton's professional life” (“Sir Isaac Newton”, 370). This book contains not only information on gravity, but Newton’s Three Laws of Motion. The First Law states that an object in constant motion will remain in motion unless an outside force is applied. The Second Law states that an object accelerates when a force is applied to a mass and greater force is needed to accelerate an object with a larger mass. The Third Law states that for every action there is an opposite and equal reaction. These laws were fundamental in explaining the elliptical orbits of planets, moons, and comets. They were also used to calculate
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
Law 1. An object continues in its initial state of rest or motion with uniform velocity unless it is acted on by an unbalanced, or net external, force.
Prompt: Define Newton’s Third Law, give three effects of it, and create an experiment designed to explore one aspect of it.

Method: If momentum is conserved in a closed system, the total momentum of the system before collision should equal the total momentum of the system after the collision. Strobe photos will be used in the calculations that will prove that momentum is conserved.
This means that the momentum of two bodies before collision will be equal to the momentum of the two bodies after they have collided and exploded apart. This will only occur if the collision is in a closed system (no other forces act on the objects) (M.Mann, 2013). An example of this is Newton’s Cradle. This is a row of five metal balls suspended by wire on a frame. When the ball at the end (ball one) is pulled and then released to collide with the ball next to it (ball two), the momentum of ball one will not be lost but will be transferred from the third ball to the fourth until it reaches the last ball which will rise up to a height almost identical to the height at which the first ball rose.
The momentum of the isolated system will remain constant after the collision because the law of conservation states that the total linear momentum of an isolated system remains constant.
The first law is, “every object in a state uniform motion tends to remain in that state of motion unless an external force is applied to it.” This means if an object at rest tends to stay at rest, then an object that is moving tends to stay moving. So when a force is applied to the rested object, it should start moving, if the force is great enough. This is commonly referred to the, “law of inertia.”
In the natural world, physicists find new discoveries constantly. Some of these discoveries include the study of motion and forces. The well-known scientist, Isaac Newton, came up with the three laws of motion, which state rules and facts about the movement of an object. Our textbook states the laws of motion, as ?A body in motion will remain in motion at a constant speed and direction unless an outside force acts upon it. The net force acting upon an object is directly related to the mass and acceleration of the object resulting acceleration is in the direction of the net force, which is the vector sum of all forces acting upon the object. Finally, the third law of motion states that when one object applies a force to another, the other object applies the same amount of force back to the first object, but in opposite directions.? With these laws of motion, we can understand in detail how our world works. Also, that the movement of an object is more complex than a simple push. This discovery is taught to students all over the world because of its great importance and will continue to enhance the knowledge of the mystery of our earth.
