What is the potential energy of the car?
The potential energy of the position of the car at the top of the hill is getting converted into kinetic energy. Where “g” is the standard acceleration of gravity which equals 9.8 m/s2. The height is determined based on the height the object could potentially fall.
What types of energy are used by a cable car?
Cable Cars and Swings Usually other forms of energy-electricity, oil, or diesel fuel-are used to accomplish these changes. The San Francisco cable car system, however, uses the decrease in the gravitational potential energy of one object to increase the gravitational potential energy of another.
How does a cable car grip work?
The cable car’s grip – essentially a 300-pound-plus pair of pliers – extends through a slot between the rails and grabs hold of the cable to pull the car along. With the grip handle at 12 o’clock (straight up), the cable is in the grip but not being grabbed.
What does a cable car conductor do?
The First Female Was Hired as a Gripman in 1998. San Francisco’s cable cars take two people to operate: a conductor, and a gripman, who—among other tasks—handles a 365-pound device that literally grabs the cable as it rattles under the track at 9.5 mph.
How does kinetic energy change on a swing?
Swings work by converting potential energy into kinetic energy, then kinetic energy back into potential energy, over and over again. The kinetic energy is the fast part of swinging; it’s the speed you have as you rush back and forth. Potential energy is the high part of swinging.
What are the factors that affects the kinetic energy?
There are two factors that affect how much kinetic energy a moving object will have: mass and speed.
Does the kinetic energy of a body depends?
Hint: Kinetic energy is the energy possessed by a body in motion. So a body in motion will have a velocity and a mass. So we can say that the kinetic energy of a body is dependent upon the frame of reference. So the kinetic energy of a body depends on its mass, velocity and frame of reference.
Does kinetic energy depend on temperature?
1). As such, it can be concluded that the average kinetic energy of the molecules in a thermalized sample of gas depends only on the temperature. So, for a given temperature, light molecules will travel faster on average than heavier molecules.
How does the kinetic energy varies with temperature?
As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.
How does temperature affect kinetic energy?
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. Increasing the kinetic energy of the particles will increase the pressure of the gas.
Does kinetic energy change when gases are combined?
Gases are composed of molecules that are in continuous motion, travelling in straight lines and changing direction only when they collide with other molecules or with the walls of a container. The average kinetic energy of the gas molecules is proportional to the kelvin temperature of the gas.
Why do all gases have same kinetic energy?
Gas particles are constantly colliding with each other and the walls of their container. The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
