Is a water fall an example of kinetic energy?
Kinetic Energy = 1/2 Mass * Velocity squared KE = (1/2)mV2 Your stream has mass and, if running, has velocity. So, this would be an example of generated kinetic energy.
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.
What is inertia in a 3 Phase motor?
A motor when running has inertia in the rotating parts, which is a reserve of kinetic energy. The kinetic energy is found as the moment of inertia times the square of the angular velocity.
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.
