How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
What happens to an object's kinetic energy when its speed doubles?
-It increases
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
When the speed of an object doubles does its kinetic energy double too?
Answer: Speed is distance over time (V=x/t). The kinetic energy of an object is calculated from the type KE=1/2mass by Speed squared. From these two formulas we can see that if the speed doubles, then the kinetic energy of an object becomes four times larger. Lets see an example: A car has a speed of 4 metres per second. Its kinetic energy is KE=1/2mass by speed squared, so its KE=1/2mass by 16 (since the square of 4 is 16). If the speed doubles and the car does 8 metres per second, its kinetic energy is: KE=1/2mass by 64 (since 8 squared gives us 64). If we divide 64/16 its 4. So we see that when speed doubles, the Kinetic Energy of an object becomes four times larger.
Explain how the kinetic energy of an object changes when the speed of the object doubles?
Kinetic energy is (1/2) (mass) (speed)2 .The only part of that formula we need in order to answer the question isthe (speed)2 part. It says that if you multiply the speed by 'K', then thekinetic energy gets multiplied by K2 .So if you double the speed, the kinetic energy is multiplied by (2)2 = 4 .
If the of an object doubles Its kinetic energy doubles?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
If the speed of an object doubles the kinetic energy of the object?
At twice the speed, the kinetic energy will be four times greater.

How does kinetic energy affect speed?
The kinetic energy of an object is proportional to the square of its speed.
How does the speed of particle affect its kinetic energy?
The higher the speed the more the kinetic energy.
What is the relationship between speed and kinetic energy?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
If the speed of an object doubles does its kinetic energy double?
As long as an object is not rotating or otherwise changing its direction of motion, and its velocity is not approaching that of light, the kinetic energy, K, of an object of mass m, and travelling at a speed v, is ½ mv².K = ½ mv²Since kinetic energy, in this relation, is directly proportional to mass, doubling the mass also doubles the kinetic energy.So the kinetic energy is increased by a factor of two.
What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.
