How do you find kinetic energy if no final velocity is given?
You can calculate kinetic energy using the formula KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. If the final velocity is not given, you would need more information or assumptions to solve for kinetic energy.
How do you find the amount of mechanical energy lost when colliding with a floor?
To find the amount of mechanical energy lost when colliding with a floor, you can calculate the difference in kinetic energy before and after the collision. Subtract the final kinetic energy (which would be zero if the object comes to a stop) from the initial kinetic energy to determine the mechanical energy lost during the collision.
Where is KE found?
If you mean kinetic energy, you'll find it everywhere where there is movement.
What does hydroelectricity do when it collects water?
'Collecting' water is not necessarily a major component of hydroelectricity. If you want to generate hydroelectricity, then what you need to find is a place where water is falling ... the more water, the more height, and the more constantly, the better. When you find that, you have mass with a lot of gravitational potential energy (the water when it's high up) converting a lot of that potential energy to kinetic energy as it falls, and all you have to do to rob some of that kinetic energy is to stick a pinwheel, a waterwheel, or a turbine into the falling water. The water turns it for you, and you can spin an electric generator that way. Hoover Dam 'collects' water behind it, in order to make the water deeper, and let it build up more potential energy before it falls. Niagara Falls doesn't collect water. It just uses the falling water that's always there.
How do you find the average kinetic energy of the gas in a container?
To find the average kinetic energy of the gas in a container, you can use the formula: KEavg = 3/2 * k * T, where KEavg is the average kinetic energy, k is the Boltzmann constant, and T is the temperature of the gas in Kelvin. Calculate the average kinetic energy by plugging in the values of k and T into the formula.
Where do you find kinetic energy?
Kinetic energy is found in moving objects. Any object in motion, whether it be a car, a person running, or a ball rolling, possesses kinetic energy. The amount of kinetic energy depends on the object's mass and velocity.
How to find the change in kinetic energy of an object?
To find the change in kinetic energy of an object, you can use the formula: Change in Kinetic Energy Final Kinetic Energy - Initial Kinetic Energy. This involves calculating the kinetic energy of the object at two different points in time and then subtracting the initial kinetic energy from the final kinetic energy to determine the change.
How do you find the ratio of kinetic energy?
The answer depends on what two (or more) things the ratio is meant to compare. The kinetic energy of several objects? The kinetic energy of an object compared to its total energy? The kinetic energy compared to its engine size?
How do you find kinetic energy using mass height potential energy and acceleration due to gravity?
I assume the situation you have in mind is an object falling from a certain height. All you need from the information you listed is the potential energy. When the object falls, once it is close to the ground all the potential energy will be converted into kinetic energy. This assumes that air resistance is negligible.
A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?
After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

What has kinetic and potential energy?
A roller coaster is a good example for a place to find both kinetic and potential energy. Before a drop, it has potential energy. At the end of a drop, it has kinetic energy. Half way through the drop, it has kinetic and potential energy at the same time.
How to find the kinetic energy of an object?
To find the kinetic energy of an object, you can use the formula: KE 0.5 mass velocity2. This formula calculates the energy that an object possesses due to its motion. Simply plug in the mass of the object and its velocity into the formula to determine its kinetic energy.
How do you find an object's mechanical energy?
To find an object's mechanical energy, you can sum its potential energy (PE) and kinetic energy (KE). The formula for mechanical energy (ME) is ME = PE + KE. Potential energy is typically due to an object's position or condition, while kinetic energy is related to its motion.
What is an example of the law of thermodynamics?
Any process in which energy is transformed - or even where energy is simply stored. Energy is always conserved, so basically you can't find a counterexample.Consider, as an example, a falling object. Potential energy (energy of position) is converted to kinetic energy (movement energy). Once it crashes on the ground, this kinetic energy is converted to heat. In the entire process, no energy is created or destroyed - it is simply converted from one form to another.
How do find an objects mechanical energy?
By calculating and adding its kinetic energy and its potential energy.
How do you find the total KE after a collision?
To find the total kinetic energy after a collision, you need to add the kinetic energies of the objects involved in the collision. The kinetic energy formula is 1/2 * mass * velocity^2 for each object, so simply calculate the kinetic energy for each object and then sum them up to find the total kinetic energy after the collision.
What is the formula uses to find mechanical energy?
Mechanical energy is potential energy plus kinetic energy. ~A.L.C.
