The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.

If the speed of a moving object is doubled which quantity associated with the object must also double?

If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.


What does a moving object has?

Kinetic energy


When the speed is doubled the force of a collision is?

quadrupled. When speed is doubled, the kinetic energy of a moving object also doubles. Since kinetic energy is proportional to the square of velocity, the force or impact of a collision increases by a factor of four.


What does it mean if an object has kinetic energy?

an object has no kinetic energy if it is not moving


What will happen to kinetic energy of the object if its mass is doubled but the velocity remains the same?

If the mass of the object is doubled but the velocity remains the same, the kinetic energy of the object will also double. Kinetic energy is directly proportional to the mass of the object, so doubling the mass will result in a doubling of kinetic energy.


What does an object have when moving that it doesn't at rest?

An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.


Which is example of kinetic energy?

Any moving object has kinetic energy.


What is energy of a moving object called?

The energy of a moving object is called kinetic energy. It depends on the mass and velocity of the object.


What kind of energy does a moving object have?

A moving object has kinetic energy, which is the energy associated with its motion. The faster an object is moving or the more mass it has, the more kinetic energy it possesses.


What happens to kinetic energy of an object if the velocity is doubled?

If the velocity of an object is doubled, its kinetic energy will increase by a factor of four. Kinetic energy is directly proportional to the square of the velocity, so doubling the velocity results in a fourfold increase in kinetic energy.


Is a plane moving kinetic energy?

kinetic energy is motion energy, therefore any object that is moving possesses kinetic energy.


What is the kinetic energy called when it is moving?

Kinetic energy is when it's moving. Potential energy is when the object is motionless.
