Work (which is a type of energy transfer) = force x distance.Look at the formulae for acceleration. The relevant formula in this case (simplified for the case that the initial speed is zero) is:
Distance = (1/2) acceleration time squared
Let's keep the acceleration constant. Note that this will also make the force constant. In this case, in twice the time your object will move four times the distance. Note that at constant acceleration, in twice the time you get twice the speed (assuming that you start at speed = 0).
Combining all of the above, to get twice the speed, you need to apply the same acceleration (and therefore, the same force) over FOUR times the distance. As a result, the amount of work required to achieve this acceleration will also increase by a factor four. Or in general, it will scale with the square of the speed.

If the speed of a player doubles his kinetic energy will?
quadruple. Kinetic energy is directly proportional to the square of the velocity, so if the speed doubles, the kinetic energy will increase by a factor of 2^2 = 4.
If the speed of a moving object doubles then what else doubles?
If the speed of a moving object doubles, the kinetic energy of the object also doubles. This is because kinetic energy is directly proportional to the square of the speed of an object (KE = 0.5 * m * v^2), so if the speed doubles, the kinetic energy will quadruple.
How kinetic energy of an object changes when the speed of an abject doubles?
The kinetic energy of an object is directly proportional to the square of its velocity, so if the speed of an object doubles, its kinetic energy will increase by a factor of four. This relationship is described by the kinetic energy equation: KE = 1/2 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity.

What is the scooter's kinetic energy when its speed doubles?
The scooter's kinetic energy will increase by a factor of 4 when its speed doubles. This is because kinetic energy is proportional to the square of the velocity (KE = 1/2 mv^2), so if the velocity is doubled, the kinetic energy is quadrupled.
How the kinetic energy of an object changes when the speed of the object doubles?
Look at the formula for the kinetic energy of an object: KE = 1/2 M V2Did you notice that " V2 " ? That means the KE is proportional to the squareof the object's velocity.So if the object's speed doubles, its KE increases by (2)2 = a factor of 4.
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 .
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.
If the speed of an object doubles its elastic electricity?
If the speed of an object doubles, its kinetic energy increases by a factor of four. This results in a fourfold increase in elastic potential energy, because kinetic and elastic potential energy are directly related.
