Why the kinetic energy is zero for object falling towards Earth from space?
The kinetic energy of an object falling towards Earth from space is not zero. As the object accelerates due to gravity, its kinetic energy increases. At the point of impact with Earth, the object's kinetic energy is at its maximum before being converted into other forms of energy upon collision.
What is an example of potential energy into kentic energy?
An example of potential energy being converted into kinetic energy is when a rock is held up in the air and then released. As the rock falls, its potential energy due to its height is converted into kinetic energy as it gains speed.
What best explains what happens when liquid water evaporates to form water vapor?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
What is energy from potenttial energy kinetic energy would be what?
A falling rock. In the air it has potential energy, as it falls it gets kinetic energy.
When water evaporates it cools the surface left behind what is this called?
It is called vaporization, and it happens because the water vapor is taking away some of the heat in the form of energy, and so the surface has less heat energy.
What happens the the kinetic energy of a falling object?
As a falling object descends, its potential energy (due to its position above the ground) is converted into kinetic energy (energy of motion). This kinetic energy increases as the object accelerates towards the ground. When the object reaches the ground, all of its potential energy is converted into kinetic energy.
What energy changes occur when a falling rock hits the ground?
When a falling rock hits the ground, its potential energy is converted to kinetic energy as it accelerates towards the ground. Upon impact, some of the kinetic energy is transformed into sound energy, heat energy due to friction, and deformation energy as the rock changes shape upon collision with the surface.
What form of energy is represented by a book falling off a desk?
The form of energy represented by a book falling off a desk is gravitational potential energy being converted to kinetic energy as the book accelerates towards the ground.
Does something gain potential energy while falling?
Yes, an object gains potential energy while falling due to its position in a gravitational field. As the object falls towards the Earth, its potential energy decreases, converting into kinetic energy.
What form of energy is a falling rock?
That is a trick question, but I believe it is kinetic energy.
What happens to the sun's energy as it is reflected back from the earth?
When the sun's energy is reflected back from the Earth, it can be absorbed by the atmosphere, clouds, or surface. Some of the energy gets trapped and warms the Earth, contributing to the greenhouse effect. The rest is radiated back towards space.
How does the increase in thermal energy of the cylinder relate to the mass of the falling object?
The increase in thermal energy of the cylinder is related to the mass of the falling object through the conservation of energy principle. As the falling object hits the cylinder, some of its gravitational potential energy is converted into thermal energy upon impact. The greater the mass of the falling object, the more thermal energy will be generated in the collision.
Is geothermal energy caused by falling water?
No, geothermal energy is heat energy stored beneath the Earth's surface from the Earth's core. It is not caused by falling water. Geothermal energy is harnessed by tapping into hot water and steam reservoirs deep underground to generate electricity or provide heating.
What kind of energy change takes place when parachutist does falling?
When a parachutist is falling, potential energy from height is converted into kinetic energy as the parachutist accelerates towards the ground. As the parachute is deployed and air resistance increases, some of the kinetic energy is converted back into potential energy, slowing the fall.
What force causes a falling object to gain kinetic energy?
Gravity is the force that causes a falling object to accelerate towards the ground, thereby gaining kinetic energy. As the object falls, its potential energy is converted into kinetic energy due to the gravitational force acting upon it.
What happens when surface water gains energy?
well, it gwets hot
How do surface currents transfer heat energy?
Surface currents transfer heat energy by redistributing warm water from the equator towards the poles and cold water from the poles towards the equator. This process helps regulate global temperature patterns and climate.
