Ek = 1/2*m*v^2, where Ek is kinetic energy, m is mass, and v is velocity. Therefore, 1/2*20*2^2 = 40 Joules.

The formula Ek =1/2*m*v^2 can be used for any point mass, that is, a mass that is small enough that it can be considered to have all its mass in one point, or a solid object that is not rotating.

How does mass and velocity effect energy?

The kinetic energy of an object is directly proportional to its mass and also to the square of its velocity. This means that the higher the mass and the velocity of an object, the higher its kinetic energy will be. Therefore, doubling the mass of an object will double its kinetic energy, while doubling the velocity of an object will quadruple its kinetic energy.


What does the amount of kenetic energy that a moving object has depend on?

The kinetic energy of a moving object depends on its mass and its velocity. The formula for kinetic energy is 0.5 x mass x velocity^2. This means that both increasing the mass or the velocity of the object will increase its kinetic energy.


What are factors that affect an object's kinetic energy?

The factors affecting kinetic energy are mass and velocity.


What is called the energy due to object's motion?

Kinetic energy is the energy associated with an object's motion. It depends on the object's mass and velocity, with the formula given by KE = 0.5 * mass * velocity^2.


Is it possible to change translational kinetic energy of an object without changing it rotational energy?

Yes, it is possible to change the translational kinetic energy of an object without changing its rotational energy. Translational kinetic energy depends on an object's linear velocity, while rotational energy depends on its angular velocity. By adjusting the linear velocity without changing the angular velocity, you can change the object's translational kinetic energy without affecting its rotational energy.

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 will affect kinetic energy?

Kinetic energy is affected by an object's mass and its velocity. The kinetic energy of an object increases as its mass or velocity increases. Conversely, kinetic energy decreases as mass or velocity decreases.


When is the the kinetic energy the greatest?

The kinetic energy of an object is greatest when its velocity is at its maximum. Kinetic energy is directly proportional to the square of the velocity of the object, so as the velocity increases, the kinetic energy increases exponentially.


What point is kinetic energy the greatest?

Kinetic energy is at its greatest point when an object is moving at its maximum velocity. This is because kinetic energy is directly proportional to the square of the velocity of an object. Therefore, the faster an object is moving, the greater its kinetic energy will be.


Which object had more kinetic energy the one that has a mass of 2 kilograms or the one with the mass of 4 kilograms and was lifted at a rate of 3meters per second?

The object with the mass of 4 kilograms that was lifted at a rate of 3 meters per second would have more kinetic energy. Kinetic energy depends on both mass and velocity, so the increased mass more than compensated for the lower velocity compared to the 2-kilogram object.


What 2 things does an object kinetic energy depend on?

An object's kinetic energy depends on its mass and its velocity. As an object's mass or velocity increases, its kinetic energy will also increase.


What is the energy arising from the motion of an object?

The energy arising from the motion of an object is called kinetic energy. It depends on the object's mass and velocity. The formula for kinetic energy is 0.5 * mass * velocity^2.


If an object is accelerating how does its kinetic energy change?

The kinetic energy of an object increases as it accelerates. This is because kinetic energy is directly proportional to the square of the object's velocity. As the object accelerates, its velocity increases, resulting in a greater kinetic energy.


What factors does the kinetic energy of an object depend on (apex)?

The kinetic energy of an object depends on its mass and its velocity. The higher the mass or the velocity of the object, the greater its kinetic energy.


How is kinetic computed?

Kinetic energy is calculated using the formula 1/2 * mass * velocity^2, where mass is the object's mass in kilograms and velocity is its speed in meters per second. It represents the energy an object possesses due to its motion.


What does the amount of kinetic energy and object has depend on?

The amount of kinetic energy an object has depends on its mass and velocity. The kinetic energy of an object increases as its mass or velocity increases. Mathematically, kinetic energy is calculated as 1/2 times the mass of the object times the square of its velocity.


What the 2 factors affect the kinetic energy of an object?

The two factors that affect the kinetic energy of an object are its mass and its velocity. The kinetic energy of an object increases with both mass and velocity.
