The property of a system that enables it to do work.
What is energy?
Any object the moves through the air or through space under the influence of gravity
What is a projectile?
A restatement of the law of conservation of energy , usually as it applies to thermal systems: whenever heat flows into or out of a system, the gain or loss of thermal energy equals the amount of heat transferred.
What is the 1st law of thermodynamics?
An abbreviation for an element or atom
What is the Atomic Symbol?
The splitting of the nucleus of a heavy atom, such as uranium-235, into two main parts, accompanied by the release of much energy.
What is Nuclear Fission?
The stored energy that a body possess because of its position.
What is potential energy?
A projectile or small body that orbits a larger body
What is a satellite?
Heat never spontaneously flows from a cold substance to a hot substance.
What is the 2nd law of thermodynamics?
Any member of a set of atoms of the same element whose nuclei contain the same number of protons but different numbers of neutrons
What is an Isotope?
The combining of nuclei of light atoms to form heavier nuclei, with the release of much energy
What is Nuclear Fusion?
Energy of motion
What is kinetic energy?
The curved path followed by a projectile near Earth under the influence of gravity only
What is a parabola?
No system can reach a temperature of absolute zero.
What is the 3rd law of thermodynamics?
An electron located in the outermost occupied shell in an atom that can participate in chemical bonding
What is a valence electron?
High-frequency electromagnetic radiation emitted by the nuclei of radioactive atoms.
What is a Gamma ray?
The product of the force and the distance through which the force moves.
What is Work?
The proportionality constant in Newton's law of universal gravitation
What is the Universal Constant of Gravitation?
The quantity of heat per unit of mass required to raise the temperature of a substance 1 degree Celsius.
What is specific heat capacity?
The time required for half the atoms in a sample of a radioactive isotope to decay
What is Half-life?
An electron (or positron) emitted during the radioactive decay of certain nuclei.
What is a beta particle?
The time rate of doing work.
What is Power?
Every body in the universe attracts every other body with a mutually attracting force. For two bodies, this force is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them:
F=(GMm)/d2
What is the Law of Universal Gravitation?
The measure of energy dispersal or spreading of energy in a system.
What is Entropy?
The conversion of an atomic nucleus of one element into an atomic nucleus of another element through a loss or a gain in the number of protons
What is Transmutation?
The nucleus of a helium atom, which consists of two neutrons and two protons, ejected by certain radioactive elements.
What is an alpha particle?
