What does Kinetic Energy means?
1/2 x mass x velocity x velocity. The energy possessed by moving object is called the kinetic energy.The kinetic energy of a moving body with certain velocity is equal to the work done on it to make it acquire that velocity.
What is an average kinetic energy of the particle of a substance?
The term kinetic energy means the energy of motion. It is calculated by multiplying one half of the mass of the moving object by the square of the velocity.
River water held behind a dam i sbest described as a form of kinetic energy chemical energy entropy thermodynamics or potential energy?
A dam holding water is potential energy. Kinetic energy requires motion. The general formula for kinetic energy is: Ekinetic = ½m·v² If there is no movement, velocity (v) is 0.
How does the kinetic energy of particles vary as a function of temperature?
In physics, the kinetic energy of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.http://en.wikipedia.org/wiki/Kinetic_energyThere is no relation to temperature. Temperature is a measure of *RANDOM* motion. A velocity is not random.
How would you explain the difference between potential and kinetic energy?
Kinetic energy is energy related to movement. The formula is (1/2) mass times velocity squared. Potential energy is energy of position. The formula for gravitional potential energy is mgh (mass times gravitation times height).
When you have kinetic energy you must have?
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
Is velocity kinetic energy?
No. This is because velocity is not a mechanical energy.
What happens to an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
Does a strawberry have kinetic energy?
If the strawberry is moving, it has kinetic energy. Anything with a mass and velocity has kinetic energy.
Where velocity is squared in the kinetic energy equation doubling an object's velocity will do what to its kinetic energy?
Multiply it by 4 (4 = 22)
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
The kinetic energy of the object moving with a velocity of 5 meter per second is 25 joules. What will be the kinetic energy when the velocity is tripled?
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
How do you solve the time by the given of mass and kinetic energy?
Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.
