Light 26 May 2013 | 11:26 am
Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has a wavelength in the ran...
Solar Cell 26 May 2013 | 11:26 am
A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell (in t...
Force 26 May 2013 | 11:26 am
In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. It is measured in the SI unit of newtons...
Acceleration 26 May 2013 | 11:26 am
In physics, acceleration is the rate at which the velocity of a body changes with time. In general, velocity and acceleration are vector quantities, with magnitude and direction, though in many cases ...
Velocity 26 May 2013 | 11:26 am
Velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion. Speed describes only how fast an object is moving, whereas velocity giv...
Motion 26 May 2013 | 11:26 am
In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement, velocity, acceleration, and time. Motion i...
Large Hadron Collider 26 May 2013 | 11:26 am
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator, and considered "one of the great engineering milestones of mankind". It was built by the European Organ...
Solar Energy 26 May 2013 | 11:26 am
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar ...
Nuclear Fusion 26 May 2013 | 11:26 am
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at very high speed and join to form a new type of atomic nucleus (e.g. The energy that the Sun emits...
Nuclear Fission 26 May 2013 | 11:26 am
In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fi...
