The Conservation Of Mechanical Energy

We will provide sustainable resources to maximize the potential conservation of the environment and will be implementing new policies to protect and preserve depleted and sparse resources.

I will start with the beginning, which is the ramp and marble. We used a marble that had more mass than the others. We did this to give the marble more potential energy. We set the marble at the top of the ramp, which gave it more potential energy as well, and released the marble. Once dropping it, it's previous potential energy transferred into kenetic energy. After this step came the metal lid. What this step showed was rolling friction and it also pushed it forward. How exactly? Well, when the marble landed, it bounced up, giving it elastic-type energy. It then fell, making it roll across the top of the lid the rest of the

The purpose of this experiment was to investigate the effects of different masses hoisted by an electric motor from ground level to a height of 1.29 m. The main purpose was to look how a change in mass affected the efficiency of our motor, but it did affect other variables such as power, current, force, etc. For this experiment, our hypnosis is that as mass increases, the efficiency increases. Because in the equation for efficiency, efficiency=gain in potential differenceelectrical energy used, gain in potential difference = mgh, the mass of an object has a direct relationship with the efficiency of the motor. In this equation, we see that efficiency is affected by the mass that is lifted, gravity, the height the mass is being lifted, and the amount of energy that is put into the system. We can see that mass, gravity, and height has a direct relationship while inputted power has an inverse relationship with efficiency.

To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.

A 0.50-kg sphere at the top of an incline has a potential energy of 6.0 J relative to the base of the incline. Rolling halfway down the incline will cause the sphere’s potential energy to be:

With the threat of zombies quickly approaching, a spring catapult needed to be built to protect Rome High School and the rest of the world from the upcoming apocalypse. That catapult is the Medieval Catapult Lier (aka MCL) which can be analyzed from the picture at the bottom of this essay. The MCL went through many adjustments such as in arm length, nail strength and tension before it could launch a tennis ball at a significant distance. Nevertheless, it was all worth it and could not have been done without the crucial subject of physics and the study of motion and energy.

The final graphical comparison we can make is the total mechanical energy of each of the basketballs, as seen in Graphs 6 and 12. The total mechanical energy is simply the sum of the kinetic energy and potential energy of the basketball. The shape of the graph is a plateau of flat near-constant mechanical energy during the air-time and sharp decreases with a rebound to a lower plateau after each bounce. As seen in the graphs for kinetic and potential energy, the well-inflated basketball had a value of total mechanical energy of 3.45 Joules when it was in the air after the first bounce and the less-firm underinflated ball had a smaller value of only 2.90 Joules after the first bounce. These values are equal to the potential energy of the basketballs at that point in time because the only energy of the basketball while it is in the air is potential energy due to gravity, the mass of the ball, and the height of the ball. The total mechanical energy also had sharp decreases down to zero total mechanical energy during the bounces as both the kinetic and potential energy are at zero. Since the total mechanical energy of the basketballs is close to the value of the potential energy of the basketballs, we can draw the conclusion that the trend of the firmer, well-inflated basketball had a smaller rate of decrease of mechanical energy in between bounces than the less firm, underinflated basketball. These decreases in total mechanical energy after bounces along with the small

For a thrilling experience in a rollercoaster ride, there is a wealth of physics involved. A part of the physics of a rollercoaster includes the physics of work and energy. The Redback is a pendulum type ride at Aussie World that includes many types of physics concepts. These concepts include the conversion of gravitational potential energy to kinetic energy, G-force, the conservation of energy and simple harmonic motion. The calculations of the ride of the Redback can be seen in Appendix B.

The purpose of this experiment was to investigate the kinetic and static friction coefficient of a friction forces acting on a wooden block by increasing the mass in each experiment. Each experiment was attempted to find the relationship between the friction force and the normal forces on the wooden block as it being slid horizontally maintaining a uniform motion by a spring scale. Every experiment was documented and finally, with the help of computer-generated graph it was understood that the Friction force and the Normal force were relative to each other. The friction coefficient was calculated to be s=0.389 and the kinetic friction coefficient was k=0.323.

1: Gather all the materials needed for the experiment (a meter tape, a ramp, 2 carts with wheels and without wheels, a rubbermat, 5-gram masses, tape, a triple beam balance, a calculator, and 2 other people to help you [Person 1 and Person 2]).

The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE.

There are two main types of energy that take effect on the catapult for it to work. The first one is Potential energy. When you pull the fork back the rubber bands are storing Potential Energy. The second energy is that helps is Kinetic Energy. When you let go of the fork the Potential Energy is transformed to Kinetic Energy. This is because when you let go the object will move because energy due to motion.

Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration.
