The kinetic energy of a body is (1/2)mv2, where m is mass and v is velocity. If the velocity were 1/3, then the kinetic energy would be (1/2)m(v/3)2, which is equal to ((1/2)mv2)/9, so when the velocity is decreased by a factor of 1/3, its kinetic energy is decreased by a factor of 1/9.

When kinetic energy doubled what happens to momentum?

If kinetic energy is doubled, the momentum will remain the same. Kinetic energy and momentum are related, but momentum depends on mass and velocity while kinetic energy depends on mass and velocity squared. Therefore, doubling kinetic energy will not affect momentum.


What happens to kinetic energy if the mass is doubled?

If mass is doubled while velocity remains constant, the kinetic energy will also double since kinetic energy is directly proportional to the mass. This is because kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2.


What is kinetic energy related to?

Kinetic energy is related to an object's mass and its velocity. The formula for calculating kinetic energy is KE = 1/2 * (mass) * (velocity)^2.


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.


Does kinetic energy increase with speed and time?

Kinetic energy increases with speed because kinetic energy is directly proportional to the square of an object's speed. Time does not have a direct effect on kinetic energy, as kinetic energy depends on an object's mass and speed but not its duration of movement.

If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.


What happens to an objects kinetic energy when the velocity is doubled?

When an object's velocity doubles, its kinetic energy increases by a factor of four. This relationship is described by the kinetic energy equation, which states that kinetic energy is directly proportional to the square of an object's velocity.


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?

When the velocity is tripled to 15 meters per second, the kinetic energy will increase by a factor of 9 (3^2) since kinetic energy is proportional to the square of velocity. So, the kinetic energy will be 225 joules (25 * 9) when the velocity is tripled.


What happens when you decrease the velocity of a car?

as you decrease the velocity of a car, you decrease the kinetic energy.


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.


As kinetic energy increases what happens to mass and velocity?

As kinetic energy increases, velocity increases while mass remains constant. The kinetic energy of an object is directly proportional to the square of its velocity, so an increase in velocity will cause the kinetic energy to increase. The mass of an object does not affect its kinetic energy directly, only its momentum.

What happens when kinetic energy is absorbed as an object moves toward the earth?

The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.


What happens to an object kinetic energy if the object speed increases?

The kinetic energy will increase. Kinetic energy is defined by K=one half mv2 where m is the mass of the object, and v is the velocity of the object. The greater the velocity, the greater the kinetic energy. Since the velocity is squared, increasing it will cause the kinetic energy to grow much faster than if you increased the mass.
