What is the kinetic energy of an object that has a mass of 30 kilograms and move with a velocity of 20ms?

The object's kinetic energy is 6,000 joules.


What is the kinetic energy of an object that has mass if 30 kilograms moves with a velocity of 20 mm?

To get the kinetic energy of an object you need both mass and velocity. As it stands it can't be answered, as "mm" isn't a recognized unit of velocity


What are objects that have kinetic energy?

Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy.Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy.Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy.Kinetic energy is 1/2 x mass x velocity squared. Therefore, any object that has both mass and velocity will have kinetic energy.An object that is moving.


Does every moving body posses kinetic energy?

Yes. Kinetic energy is given by the formula K=.5mv2, where m is the mass of the object in kilograms and v is the velocity in meters per second. As long as it has mass and velocity, it has kinetic energy.


As an object falls freely does kinetic energy of the object increase?

Kinetic energy increases. The kinetic energy is related to the velocity, KE=1/2mv2. As an object falls freely the velocity increases and therefore the kinetic energy increases. or this will be a good answer to go by when an object has more potential energy. It will transform into kinetic energy.


Can a single object have kinetic energy but no momentum?

No, an object cannot have kinetic energy and no momentum. Here's the reason: Kinetic energy is the energy an object derives from being in motion. If an object is moving, it has some non-zero velocity. Momentum is the product of mass (which the object will have) and velocity, which it must exhibit to have kinetic energy. That is why an object cannot have kinetic energy with no momentum.


What influences the kinetic energy of an object?

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.


How do you calculate velocity using kinetic energy?

Kinetic energy = 0.5 * mass * velocity^2 So the velocity of an object with a known mass = sqrt(kinetic energy /0.5mass)


What determine the kinetic energy of an object?

The mass and velocity of the object.


What happens to kinetic energy if the speed of an object increases?

The kinetic energy will increase. Kinetic energy is defined by K=one half mv2 where m is the mass of the object, and v is the velocity of the object. The greater the velocity, the greater the kinetic energy. Since the velocity is squared, increasing it will cause the kinetic energy to grow much faster than if you increased the mass.


The kinetic energy of the object moving with a velocity of 5 meter per second is 25 joules. What will be the kinetic energy when the velocity is tripled?

The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.


If the speed of an object doubles its kinetic energy?

If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.


What is the total amount of kinetic energy in an object?

The kinetic energy in an object is EK=mcV where V is the velocity, a vector.


What factors can calculate kinetic energy of an object?

KE = (1/2)mv2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules


How much kinetic energy does an object have?

Depends on its Mass and Velocity. Kinetic Energy = (1/2) * Mass * Velocity^2


An object that has kinetic energy must have?

An object that has kinetic energy must have momentum, velocity, and speed. Momentum is mass times velocity. Kinetic energy is mass times velocity squared. Speed is distance divided by time. Kinetic energy is the energy of the object's motion. An object that has kinetic energy must have momentum because is the force or speed of movement. For example the ball gained momentum as it rolled down the hill. An object that has kinetic energy must have momentum, velocity, and speed because if an object is in motion (has kinetic energy) it must be either gaining, losing, or at a constant momentum, it must have a velocity (basically speed) and speed because when an object is in motion, it MUST have a certain velocity or speed.


If mass increases but kinetic energy is kept the same what happens to the velocity of the object?

mass doubles the object, but if velocity is increased and mass and kinetic energy are kept the same then the object quadruples


Kinetic energy depends on what?

The mass and velocity of the object


Is kinetic energy is the energy an object has to due to its motion?

Yes, kinetic energy is directly related to the velocity of an object by the formula. KE=1/2mv2 where m is mass and v is velocity


Is it possible for an object to have momentum without having kinetic energy?

No, because in order to have momentum, an object must have velocity. Velocity cannot be obtained without kinetic energy.


What is the formula for computing the kinetic energy of an object?

The kinetic energy of an object depends on its mass and velocity. The relevant formula is: K.E = 0.5mv2 , where m = mass and v = velocity.


What happens to the kinetic energy of an object if its mass doubled but the velocity remains 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


What objets has kinetic energy?

kinetic energy is the energy an object has by virtue of its motion- therefore any object that is moving possesses kinetic energy ( and the kinetic energy is proportional to both the mass of the object and the object's velocity, according to the equation KINETIC ENERGY= 1/2 mv2)


Equation for kinetic energy?

Kinetic Energy can be found by (1/2)mv2 where m = mass of object and v = velocity of object.


Which type the amount of kinetic energy an object has depend on?

The amount of kinetic energy an object has depends on its mass and speed.
