How does the mass of an object affect its kinetic energy?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 5

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.

Answer 6

The kinetic energy of an object is directly proportional to its mass - meaning that the higher the mass of an object, the greater its kinetic energy, given the same velocity. This relationship is described by the formula: kinetic energy = 0.5 x mass x velocity^2.

Answer 7

Yes because KE=(1/2)mv2

m is mass
