Abstract The aim of this experiment was to establish whether speed affects braking distance of a car travelling down a ramp at different heights. The method involved performing a controlled test before changing the angle of the ramp for the other four tests. To do this, three text books were used to prop up the ramp and the height was increased for each test. These trials were done five times, changing the variable after each set, measuring the speed and changing the angle of the ramp. The results

to investigate the conservation of total energy. There are two parts to this experiment: To investigate the conservation of energy for a ball that is launched upwards in a vertical direction; and To investigate the principle of energy conservation using an air track and a glider. For the first part, the principle of conservation of energy is investigated by launching a ball vertically and comparing its total energy at the time of launch to its energy when it reaches its highest point. For the

Kinetic energy is the energy of mass in motion. The most important property of kinetic energy is its ability to do work. Energy of motion is usually expressed as E=½ mv2 and as such, to change the kinetic energy of an object, work must be done on it (Urry, 2017). Moreover, kinetic energy can be elastic or inelastic, which is the transfer of energy from one body to another in a collision. Additionally, kinetic energy can convert from one form of energy to another. Kinetic energy can be stored and

Abstract: The aim of this experiment to determine whether energy is conserved as it is converted from one form of energy to another using a cart which rolls up and down an incline plane. The cart was given velocity by releasing a compressed spring within the cart onto a hard object (force sensor) and then letting it move and up and down the incline plane. Logger Pro recorded the carts velocity and displacement while the cart was in motion as well as the force felt on the sensor at the bottom of the

------------------------------------------------- Chapter 1 Review Questions 1. What is the goal of science? The major goal of science is to ask & answer questions about the physical universe that we live in. 2. How is observation different from imagination? Observation gathers only what data is obviously true. Imagination can go anywhere—factual or not. 3. Write an equation in words & then in symbols for the following sentence: The price of coffee beans is equal to the weight

horizontal. Building on this idea, this experiment sought to predict the range of a projectile along the horizontal by determining the initial velocity at which the ball was being launched using a ballistic pendulum. The concepts of conservation of energy and momentum were used to calculate the initial velocity. In the first part of this experiment, the velocity at which the ball was launched had to be determined. A ball of mass m was launched from a projectile launcher set at short, medium, or long

about different types of physics. Roller coasters are a commonly used example of potential and kinetic energy, and also by learning about roller coasters a person can learn about forces. Roller coasters can be very different, but they usually follow the same basic track to make the ride more thrilling.The ride starts when the chain pulls the cars up the first hill. The first hill is the tallest, so the potential energy is at its most at the

Alternative Energy Introduction: Last year for my science fair project I personally invented my own version of a sun tracking solar panel. The solar panel was able to produce three watts of power per hour regardless of its small three-inch by three-inch size, showing me that having direct access to the sun can increase the amount of watts gained multifold. This year, instead of researching over the topic of solar panels, I instead inquired alternative methods of producing energy from economical

ball bounce height was 110.6 cm. My hypothesis was supported. WHY DID IT HAPPEN? When the ball was held at a higher height, it had more Gravitational Potential Energy, because G.P.E depends on height above the ground, and mass of the object (mass remained the same). Since the ball had a greater amount of G.P.E, it converted into more kinetic energy, or motion energy, when it was dropped. So, it hit the ground with a
