Mass is directly proportional to the amount of kinetic energy an object posses according to this formula.
Ek= 1/2mv2.
There are two factors, which can alter the amount of kinetic energy.
1. The velocity of an object, how much momentum does the object carry.
2. The mass, small or big.
if an object with mass of 5kg travelling at 7m/s has an overall kinetic energy of 123j. directly if an object weighing twice to have the same kinetic energy, its mass should be 4.959kg.
you can get this using v2=Ek/0.5m.
Explanation 1: Informally, you might notice that a "heavy" object hits normally hits you harder than a "light" object - it will hurt more. That reflects the fact that it has more kinetic energy.
Explanation 2: For example, imagine an object of 1 kg, moving at a certain speed. It has a certain kinetic energy. A second object, also with 1 kg, moves at the same speed (alongside the first one). You would expect it to have the same kinetic energy as the first one (and it does, according to physics). The combined energy of the two can be expected to be the sum of the energy of the individual objects. If they happen to stick together, and they continue moving at the same speed, there is no particular reason for the kinetic energy to suddenly increase - or decrease. Thus, the combined object can be expected to have twice the kinetic energy of the individual objects.

Kinetic Energy=1/2 * mass * velocity2
Thus Kinetic Energy is Directly Proportional to mass of a body.
Gravitational Potential Energy = mass * g * h
where g is the acceleration due to gravity and h is the height at which the body is placed.
Thus gravitational potential energy is also directly proportional to mass of the body.
But electrostatic or magnetic potential energy are independent of mass.

A more massive object will have greater KE than a less massive object, assuming they both have the same velocity. KE = 1/2mv2, where m is mass in kg, and v is velocity in m/s.
Yes because KE=(1/2)mv2
m is mass
It depends on mass and velocity. ans : it depends on the mass & speed of the moving object. no, it depends on the work & energy.
Kinetic energy is the energy an object has due to its mass and its velocity. Kinetic energy is calculated with the equation: Ek = ½ mv² Since kinetic energy is proportional to mass and velocity, any object moving very slowly has a small amount of kinetic energy. Also, any very small object normally has a small amount of kinetic energy. For example, a soccer ball rolling down a hill might have a relatively small amount of kinetic energy.
The mass and velocity of an object determine the kinetic energy of an object. The equation for kinetic energy is KE = 1/2mv2, where m is mass in kg, and v is velocity in m/s.
Kinetic Energy is 1/2 mass x the square of speed (KE = 1/2 mv^2)
it is directly related to the weight or mass of an object
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
The factors affecting kinetic energy are mass and velocity.
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.
Use the formula for kinetic energy: KE = (1/2) mv2 (one-half times the mass times speed squared). Clearly, the amount of kinetic energy depends both on the mass and on the speed of the object.
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
The kinetic energy depends on the object's mass, and on its speed.
Kinetic energy is the energy of motion. The amount of kinetic energy an object has depends on the mass of the object and the speed of the object. The equation is: K= (1/2)mv^2, where K=kinetic energy, m=mass, and v=speed of the object.
Kinetic energy depends on mass and speed. It is not directly affected by any force; however, a force can, of course, make an object move faster or slower, and thus indirectly affect kinetic energy.
Kinetic energy of a mass is directly proportional to two variables: its mass and speed. Many mistake kinetic energy as being proportional to mass and velocity; it is, in fact, mass and speed. (With all technicalities aside, the speed is the factor that matters in computing kinetic energy of an object or a mass). Kinetic Energy = 0.5mv2 (m = mass and v = speed of the mass) Therefore, if the speed of the object increases, the kinetic energy increases. If the speed of the object decreases, the kinetic energy decreases. Similarly, if the mass of the object increases while traveling, its kinetic energy increases. If the mass of the object decreases, the kinetic energy decreases. All has to do with the directly proportional relationship between the two variables and the kinetic energy.

Look at the equation for kinetic energy. It clearly shows that the kinetic energy depends on the object's mass, and its speed.
