On earth the weight an height of an object give an object what type of potential energy?
Gravitational energy
What is the name of a force that pulls object towards the centre of the earth?
gravity
What happens when the only force acting on an object is gravity?
In that case, the object is said to be in "free fall". If the gravity is due to the attraction from a single object, such as Earth, the other object will accelerate towards Earth or whatever.
What form of energy is associated with the position of an object in Earth's gravitional field?
Potential energy
Does potential energy decreases as an object falls to earth?
Yes.
Why the kinetic energy is zero for object falling towards Earth from space?
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.
Energy which is a result of an object's height above the earth is?
Energy which is a result of an object's height above the earth is potential energy.
What is the spectrum of an object that shows blueshift?
The object moving directly towards earth
What if there's more gravity on earth?
weight of all object on the earth will increase,will attract more object from space towards it.
On earth the weight an height of an object give an object what type of potential energy?
Gravitational energy
Where does the heat energy come from?
from steam produced by earth
Electricity traveling through a wire is an example of?
a force applied by a simple machine energy flowing through the water cycle Earth's gravitational pull on an object energy being transferred from place to place
What force pulls falling object towards earth?
Gravity pulls objects towards each other.
What is the name of the force that pulls object down towards the earth?
Gravity.
What is the name of a force that pulls object towards the centre of the earth?
gravity
When you lift an object off the ground how are you changing its energy?
You are changing the object's gravitational potential energy. Gravitational potential energy is the energy due to position of the object above the Earth. This energy has the potential to be transformed into Kinetic Energy if the object falls.
weight?
The gravitational pull acting on an object towards the earth's center.
