Answer:In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.[note 1] Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.

Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature.

Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.

Living organisms require energy to stay alive, such as the energy humans get from food. Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy. The processes of Earth's climate and ecosystem are driven by the radiant energy Earth receives from the sun and the geothermal energy contained within the earth.

Explanation:

Some forms of energy (that an object or system can have as a measurable property)

Type of energy Description

Mechanical the sum of macroscopic translational and rotational kinetic and potential energies

Electric potential energy due to or stored in electric fields

Magnetic potential energy due to or stored in magnetic fields

Gravitational potential energy due to or stored in gravitational fields

Chemical potential energy due to chemical bonds

Ionization potential energy that binds an electron to its atom or molecule

Nuclear potential energy that binds nucleons to form the atomic nucleus (and nuclear reactions)

Chromodynamic potential energy that binds quarks to form hadrons

Elastic potential energy due to the deformation of a material (or its container) exhibiting a restorative force

Mechanical wave kinetic and potential energy in an elastic material due to a propagated deformational wave

Sound wave kinetic and potential energy in a fluid due to a sound propagated wave (a particular form of mechanical wave)

Radiant potential energy stored in the fields of propagated by electromagnetic radiation, including light

Rest potential energy due to an object's rest mass

Thermal kinetic energy of the microscopic motion of particles, a form of disordered equivalent of mechanical energy

What could you do to change the volume of a gas?
Lorico [155]
The ONLY way to change the volume of a sample of gas is to transfer it to a container with different volume.
Simply changing its temperature or pressure in the same jar won't do it. Any amount of gas always fills whatever container you keep it in.

__________ is when a person becomes less sensitive to a drug. A. Tolerance B. Craving C. Addiction D. Dependence
Luden [163]
A) Tolerance

Tolerance is developed after using a drug repeatedly, so the body adapts to it. Because of that, people who develop a tolerance would then need to use more of that drug to get the same effect.

A basketball player jumped straight up to grab a rebound. If she was in the air for 0.80 second, how high did she jump?
Kazeer [188]
-- She went up for 0.4 sec and down for 0.4 sec.

-- The vertical distance traveled in gravity during ' t ' seconds is

                   D  =  (1/2)  x  (g)  x  (t)²

                       = (1/2) (9.8 m/s²) (0.4 sec)²

                       =    (4.9 m/s²)  x  (0.16 s²)

                       =      0.784 meter        ( B )
