Why the kinetic energy is zero for object falling towards Earth from space?
Franko88
It isn't. Kinetic energy is 1/2 x mass x speed squared, so if an object has mass, and it moves, it follows that it has kinetic energy.

How does accretion heat a planet?
During accretion, any object falling towards a planet will acquire a velocity because of the gravitational attraction from the planet. So, the object will have a kinetic energy due to its motion. During the the collision the kinetic energy is converted to heat energy, and the remain of this heat is actually heating the planet.
Object hanging on a tree a kinetic or potential energy?
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
What is the condition of an object if it has kinetic energy?
Kinetic energy is the energy of movement.
How does energy change from potenial energy to kinetic energy?
A object falling form a height, h. At h it has graventational potential energy and when it starts to fall this energy tranferes into kenetic.ability toput mass of any sort into a motion of accelleration therefore resulting in having potential of producing kenetic energy into said mass
How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
What happens the the kinetic energy of a falling object?
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
What has both kinetic and potential energy?
A falling object.
What is the energy in an object about to fall?
the energy in an object about to fall is potential energy then kinetic energy because when the object is not falling, it has potential energy but when it's actually falling, it has kinetic energy.
What has potntial energy that changes to kinetic?
A falling object changes from gravitational potential to kinetic.
What form of energy is a falling rock?
That is a trick question, but I believe it is kinetic energy.
What is the kinetic energy of the free falling object that eventually stop on reaching the ground?
Once the object has reached the ground, its kinetic energy is zero.
What is an example of of an object with kinetic energy?
Kinetic Energy is the energy of motion, so anything that is moving has kinetic energy. Examples : a ball rolling down a ramp a spoon falling off a table a Baseball hurtling towards a window a moving train a coin falling from the roof of a building (generally anything with a rest mass which isn't at rest)
What force causes a falling object to gain kinetic energy?
gravity
As an object falls towards the ground what happen to the kinetic energy of the object?
Increases
Which examples illustrates an object with kinetic energy?
A skateboard rolling across the street A hockey puck sliding across the ice
What kind of energy is in a falling object?
Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)
What happens to the potential energy as the kinetic of an object increase?
An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
