Conservation of Momentum Investigation

The ball now has kinetic energy. Kinetic energy like momentum in that it comes from the mass of the object and its velocity. Kinetic energy was transferred from the plunger to the ball just like momentum was but only if the collision was elastic. During and elastic collision kinetic energy is conserved. The balls kinetic energy is half of its momentum squared. This means the balls momentum is its mass multiplied by velocity, and then it is squared and divided by two. If the velocity or speed of the ball is reduced by one half then the overall kinetic energy is reduced by a factor of four (Kirkpatrick and Wheeler p.106)

“Standard physics has no explanation for this and an error has not yet been found… There is no explanation for this behavior in standard physics because it violates the conservation of momentum, and Shawyer 's own attempt to explain it using special relativity is not convincing, as this

Momentum is the mass of an object times it’s velocity. The velocity of an object would be it’s rate and change of direction. A collision occurs when two or more objects collide with each other. This causes the kinetic energy, the energy of motion, to be transferred

In light of our final exam, the chuck a duck project, we are to learn about projectiles, trajectory, and the factors that affect these things.

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

5. A hockey player hits a puck at one end of an empty skating rink. The puck travels across the ice in a straight line until it is stopped by the goal at the other end. Explain how each of Newton’s laws of motion applies to this situation.

At the scene of this collision Macarthur Bl is a two-lane N/B and S/B roadway and 55th Av is a N/B and S/B roadway. Macarthur Bl has a traffic control light facing N/B and S/B and 55th Av has a traffic control light having W/B. The roadway is straight and level. The surface is composed primarily of asphalt.

Let the mass of the fired bullet be Mb. It is fired at an initial velocity of v. The momentum

1. The force of the window on the bug because the bug is just flying, but the force of the window at a given speed is much greater creating the force to splatter the bug.

(Melvin, Mangonel - “Physics of Catapults”) The speed and distance of the projectile depended on how much force the catapult applied to the projectile, and the momentum depended on the mass and the velocity of the projectile (dead diseased cow, or flaming

Results - The results supported that of the first experiment. The participants in the smashed condition overestimated the speed of the cars. The participants who reported seeing broken glass: Condition|% who answered yes. Smashed|32%, Hit|14%, Control|12%.

Another basic element of basketball is that of passing the ball to another teammate. The physics involved in this process are velocity, momentum, and impulse. The ball has a mass and when it is thrown a velocity of the ball in created. From these two parts momentum is derived, P=mv (Kirkpatrick Wheeler 106). While playing basketball it may be to your advantage to increase or decrease the momentum of the ball when passing to a teammate depending upon the situation.

=== The two theories I have discussed both link in with the collision theory. - Ineffective Collision - There is not enough energy to bring the two particles together, so they move away and there is no collision. - Effective Collision - = ==

If the mass of the reactants are compared to the mass of the products, then the mass will stay the same because the law of conservation of mass states that in any given chemical reaction, the total mass of the reactants equals the total mass of the products.

HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction.
