What is Energy
Define energy
In its most common definition, energy is the ability to do work. In other words, everything that can do work has energy.
What is the SI unit of energy?
Joule (J)
List various types of potential energy
The various types of potential energy include
Elastic potential energy
Electric potential energy
Chemical potential energy
Nuclear potential energy
Gravitational potential energy
Define radiant energy.
Radiant energy is the energy of electromagnetic radiation
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat?
Yes and no
What is the main source of energy for earth?
The energy of the sun
What is the formula for potential energy?
The formula for potential energy is
PE = mgh
Where,
m = mass of the object
g = acceleration due to gravity
h = height above the earth surface
Define gravitational potential energy.
The energy stored in an object because of its height above the ground is called gravitational potential energy.
Define thermal energy.
Thermal energy is the internal energy of an object due to the motion and collision of atoms.
Are there different types of black holes?
Yes, there are different types of black holes.
Define potential energy.
The energy that is stored in an object because of its position is called potential energy.
What is the formula for kinetic energy?
The formula for kinetic energy is
K = ½ mv2
Where,
m = mass of an object
v = velocity of an object
K = kinetic energy
Define elastic potential energy.
The energy stored in a stretched or compressed object is called elastic potential energy.
Define sound energy.
The energy produced due to vibration of an object is called sound energy.
Can you go fast enough to get enough mass to become a black hole?
Traveling at high speed does not affect your mass
Give some examples of potential energy.
Any object that is at rest position has potential energy. For example, a book on a table, water in a lake, trees, and mountains have potential energy.
Define nuclear energy.
Nuclear energy is the potential energy of the particles such as neutrons and protons that are present inside the nucleus of an atom.
Define electrical energy.
An electrical energy is the energy of moving electrons.
What makes heat rise?
Radiation
List various types of potential energy.
chemical, elastic, electrical electromagnetic, gravitational, nuclear, and thermal energy.
Define chemical energy.
The energy stored in the chemical bonds of atoms and molecules is called chemical energy.
Define mechanical energy.
The sum of kinetic energy and potential energy is called mechanical energy.
Why is light pure energy?
Light is not pure energy.
