Why does a small increase in speed produce a large increase in kinetic energy?

Kinetic energy is proportional to (depends upon) the square of the speed (velocity). If the speed is doubled then the KE is increased by a factor of 4 (2 squared).


Describe the change in kinetic energy when the temperature of an object increases?

The more an objects kinetic energy increases the more it's temperature increases. An object that is traveling at 30 miles per hour will have a higher temperature than an object traveling at 10 miles per hour. This is in part due to friction. Mostly however, it is due to the fact that kinetic energy excites atoms in the object raising the objects temperature. You could put it like this: temperature = energy + atoms. Hope this helps.


What factor are involved in determining the kinetic energy of a amoving object?

mass and speedKE = 1/2mv2, where m is mass in kg, and vis velocity in m/s.

Sunlight is an example of renewable primary energy source.


Why does heavier object have a greater momentum if light and heavy object have the same kinetic energy?

Well, the equation for momentum is mass x velocity. So, p (momentum)= m x v. The equation for kinetic energy is m x v(squared)/2. Let's say that there are two objects. One is 50 kg, and the other is 30 kg. These objects can both have the same kinetic energy, even though one of them has a larger mass. The determining factor in them both having the same kinetic energy, even though one of them has a larger mass is because of different velocities. The 50 kg object has a velocity of 7 meters/second, and the 30 kg object has a velocity of 9.036961141 meters/second. If you do the math, they both have the same kinetic energy (about the same). 50 kg x 7 m/s = 350 kg x m/s. 30 kg x 9.036961141 = 271.1088342. There is an inverse relation between the momentum of an object and its mass. The mass is the factor that influences momentum more than the velocity; that is why an object with a greater mass will have a greater momentum than the one with a lesser mass, only if they both have the same kinetic energy.

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.


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.


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.

State any one factor which determines the kinetic energy of a body?

One factor affecting the kinetic energy of a particle (or body) in is the viscosity of the medium through which that particle moves


What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?

Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4


Is doubling a kinetic energy source by mass bigger than when you double its speed?

Doubling the mass will double the kinetic energy. Doubling the speed will increase kinetic energy by a factor 22 = 4.


Does kinetic energy increase with speed and time?

Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
