EXPLANATION:-

We know that:-

K.E = 1/2 m v^2

=> K.E is directly proportional to the square of velocity.

Conclusion:-

If velocity becomes tripled than K.E. becomes Nine times to its initial value.

If velocity is tripled, the kinetic energy of an object will increase by a factor of nine. This is because kinetic energy is directly proportional to the square of the velocity according to the equation KE = 0.5 * m * v^2.

Kinetic energy is the one half the mass multiplied by the square of the velocity, K=1/2mv2. If mass is doubles, the kinetic energy doubles. If the velocity doubles, the kinetic energy is increase by 22 or 4 times. Therefore, if both the mass and velocity are doubled, the kinetic energy increases by a factor of 8.

This depends on how the momentum is tripled.

Momentum = mass * velocity, (p=mv)

Kinetic Energy = (1/2) * mass * velocity squared, (K = (1/2)mv2)

Momentum can be tripled by tripling the mass, in which case Kinetic Energy would also be tripled. Momentum can also be tripled by tripling the velocity, in which case Kinetic Energy will be tripled by a factor of 9.

Momentum could also be tripled by a combination of chaining the masses and velocities, in which case the Kinetic Energy could increase by a lot or even decrease. All we know for sure is that if momentum is tripled, Kinetic Energy will remain above zero (assuming you're not 'tripling' a zero momentum).

Look at the formula for kinetic energy. Clearly, the kinetic energy is proportional to the square of the velocity: the formula is (some other factors) times speed squared. Therefore, if you change the velocity by a factor of "a", the kinetic energy will change by a factor of "a squared".

Assuming you are nowhere near the speed of light, twice the speed will result in four times the kinetic energy.

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.


If the velocity of an object is tripled its kinetic energy is multiplied by?

When the velocity of an object is tripled, its kinetic energy is multiplied by 9. This is because kinetic energy is proportional to the square of the velocity (KE = 1/2 * m * v^2), so when the velocity is tripled, the kinetic energy is calculated as (3v)^2 = 9 * v^2.


If the speed is tripled the kinetic energy will .?

If the speed is tripled, the kinetic energy will increase by a factor of 9. This relationship is based on the equation for kinetic energy, which is proportional to the square of the velocity.


If speed is tripled then its kinetic energy of a mass is?

The formula for Kinetic Energy of an object is mv2/2 where m: mass of object and v:velocity of object Therefore when the speed of an object is tripled, then its kinetic energy becomes 9 times


What happens to an objects kinetic energy as its velocity increases?

Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2


What is result of kinetic energy if speed is tripled?

If the speed is tripled, the kinetic energy will increase by a factor of 9 (3 squared) since kinetic energy is proportional to the square of the speed.


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.


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.


What happens when you decrease the velocity of a car?

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


How does the kinetic energy of substance increase?

As the kinetic energy of matter is increased, the temperature increases and phase changes from solid to liquid or liquid to gas occur. If pressure is low enough, sublimation could occur.


What happens to kinetic energy as velocity increases?

particles speed up.
