Terms in this set (28)
what is kinetic energy
the energy of motion
what is potential energy
stored energy. The amount depends on its position above ground or the composition of object, like food
Name the 3 ways in which heat is transferred
conduction, convection, and radiation
Name the 2 main types of energy
kinetic and potential energy
Name at least 6 forms of energy
thermal, electromagnetic, nuclear, mechanical, sound, chemical, elastic, electric
Matter is anything that has ________ and _______________
mass and volume
how much room something takes up
Name at least 2 things that are not considered matter
light, sound, ideas and feelings
In a gas, molecules move
In a liquid, molecules move
by sliding past each other
In a solid, molecues move
by twisting and vibrating
Physical properties are
how something looks, feels, the size etc.
Chemical changes occur when
a substance is changed into a new substance
Law of conservation of energy
Energy is never created or destroyed. It is changed from one form to another
the ability to cause change
Mechanical energy is
a type of energy that moves an object
Chemical energy is
energy that is stored in matter
Electromagnetic energy is
transmitted through space in the form of waves
The amount of kinetic energy in an object depends on its
mass and speed
the potential energy associated with objects that can be stretched or compressed
energy transformations (conversions)
A change from on form of energy to another
fuel created from remains of plants and animals over millions of years. A type of chemical energy
Gravitational Potential Energy
potential energy that depends upon an object's height.
The potential energy stores in teh nubleus of an atom
The transfer of thermal energy from one object to another. Flows from hot to cold.
movement of heat (thermal energy) from one object to another when they are touching.
Heat is transfered by the movement of particles (liquids or gases) due to uneven temperatures. Particles are heated up, expand and rise. The particles eventually cool off, contract and become more dense which makes them sink.
Thermal energy that travels as electromagnetic waves which include visible light, microwaves, and infrared light.
