ENERGY VOCAB

Question 1

MOTION

Answer 1

motion is when something’s position changes in relation to another object

Question 2

GRAVITATIONAL POTENTIAL ENERGY

Answer 2

gravitational potential energy is the energy stored in an object as the result of its vertical position or height

Question 3

ELECTRICAL ENERGY

Answer 3

electrical energy is the energy of electrical charges

from the flow of charged particles, such as electrons, through a conduct

Question 4

EQUATION FOR MECHANICAL ENERGY

Answer 4

MECHANICAL = POTENTIAL + KINETIC

Question 5

ENERGY

Answer 5

energy is the ability to do work

Question 6

FORCE

Answer 6

force is a push or a pull

Question 7

EQUATION FOR WORK

Answer 7

WORK = FORCE x DISTANCE
(W = F x D)

Question 8

EQUATION FOR KINETIC ENERGY

Answer 8

KINETIC = ONE HALF x MASS x SPEED/VELOCITY squared
(K = 1/2 x M x V squared)

Question 9

EQUATION FOR GRAVITATIONAL POTENTIAL ENERGY

Answer 9

GRAVITATIONAL = WEIGHT x HEIGHT
(G = W + H)

Question 10

LAW OF CONSERVATION OF ENERGY

Answer 10

the law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another

Question 11

ELASTIC POTENTIAL ENERGY

Answer 11

elastic potential energy is energy stored as a result of applying a force to deform an elastic object. the energy is stored until the force is removed and the object springs back to its original shape, doing work in the process

Question 12

WORK

Answer 12

something produced or accomplished by effort, exertion, or exercise of skill

Question 13

EQUATION FOR POWER

Answer 13

POWER = WORK/TIME
(P = W/T)

Question 14

MECHANICAL ENERGY

Answer 14

mechanical energy (kinetic energy or potential energy) is the energy of either an object in motion or the energy that is stored in objects by their position

Question 15

KINETIC ENERGY

Answer 15

kinetic energy is the energy an object has because of its motion

Question 16

THERMAL ENERGY

Answer 16

the total potential energy & kinetic energy of particles in an object

Question 17

POTENTIAL ENERGY

Answer 17

potential energy is when an object has the potential to do work

Question 18

CHEMICAL ENERGY

Answer 18

chemical energy is defined as the energy which is stored in the bonds of chemical compounds (molecules and atoms). it is released in the chemical reaction and mostly produces heat as a by-product, known as an exothermic reaction

Question 19

POWER

Answer 19

power is the rate at which work is done

Question 20

NUCLEAR ENERGY

Answer 20

nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. this source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together

Question 21

ELECTROMAGNETIC ENERGY

Answer 21

electromagnetic energy is radiant energy that travels in waves at the speed of light. It can also be described as radiant energy, electromagnetic radiation, electromagnetic waves, light, or the movement of radiation
