The Physics Of Mechanical And Kinetic Energies

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)

1. Find the westward component of a resultant vector 85.42 unit, 23º W of N.

Section Heading: The reason I think the golf ball will go the farthest is because it has the most density and density means “to have the degree of compactness of a substance.”I believe the tennis ball will go the second farthest because it has almost little density and it has no core at all and it's hollow.When the ball is hit with the most density it will give it the weight and power to travel great distance but unless the ball has to much weight it won’t go far.The baseball has the least greatest density so I gathered information

9. The total energy is constant for most of the time until the ball is released and caught up and down in free fall, because extra force of the person actions changes the energy. The energy should remain constant because the kinetic and potential ratio energy

Introduction: Accuracy and precision were the major aspects of the lab. Accuracy is how close the average of the measured values are to the actual value. Precision is the closeness of repeated measurements. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. The volume is determined by measuring with a ruler and by water displacement. The standard

Are forth step was the basketball to be hit by the tennis ball and fall through a hoop. This step had potential and kinetic energy and force. The tennis ball used the force from the baseball to hit the basketball. The basketball was storing up potential energy while the rest of the machine was running. When the tennis ball hit the basketball the potential energy was released. As the basketball was falling through the hoop it had kinetic energy.

Introduction: The experiment being tested is worth conducting as it can help people decide which ball to get if they want a bouncy one, either it is expensive, cheap, big or small. One fact on balls is that they are different and they bounce differently and are used differently. A netball has thinner layers than what a basketball does, and a basketball is more used for bouncing that a netball.

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.

During this stage the energy which occurred was gravitational potential energy and also kinetic energy. Gravitational potential energy occurred when the marble went down the ramp which was on a slight downcline. Whilest gravitational potental energy was occurrig kinetic energy also was being produced in a rapid rate.

The weight of the marble in the container will cause the elevated side of the seesaw to lower, and the other side to be lighter and elevate, which is mechanical energy. The mechanical energy is in its potential form when the seesaw isn’t moving, and when it is moving then it is in its kinetic form. The other side of the seesaw has an object, which when elevated will hit a platform, which has a marble placed on top of it. When the platform receives enough force to be raised, then the marble will roll down the slanted platform, which is gravitational energy. The gravitational energy is in its potential form when the marble is on the platform, and when the marble is rolling down the slanted platform, then it is in its kinetic form. The rolling marble will hit a domino and this will cause the domino to fall and hit another domino, which is gravitational energy, and this chain reaction will stop when the last domino has fallen. The gravitational energy is in its potential form when the dominoes are standing, and when the dominoes are falling,

As the tennis server prepares to swing their racket in the serve, they bend their knees, which stores elastic potential energy in their legs. This elastic potential energy is also referred to as strain energy. As the legs are bent the muscles and tendons are stretched in a way that stores this strain energy(biochmechanics). The greater the bend and stretching in the legs, the greater the power generated as the legs are extended(biomechanics). As the tennis player extends their legs this elastic potential energy is converted to kinetic energy and a ground reaction force is generated. This ground reaction force can also be called normal force. As the player extends their legs the tennis court ground in contact with their feet is compressed

As the distance that the object is released increases, the object will accelerate for longer than the previous release, gain more speed and leave a greater sized crater. This is because of Newton’s Second Law, which states that the force applied to an object is directly proportional

Some of this energy is transferred to the other player, but if they are properly setting the pick that player should not move. Since both players come essentially to rest, we can say that the energy was lost through and inelastic collision.

but when we compare the ball with the earth then it is extremely small. This indicates that size

Conservation of energy is...TE = PE + KE + WE; where total energy is made up of potential energy, kinetic energy, and work energy. Your total energy is conserved while walking. The potential energy is the biochemical potential of your muscles and frame, which is converted by work into kinetic energy, which is the walking part.
