energy types

Question 1

gravitational energy

Answer 1

an energy that is related to gravitational force or to gravity.

Question 2

radiant energy

Answer 2

the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment.

Question 3

chemical energy

Answer 3

energy stored in the bonds of atoms and molecules

Question 4

thermal energy

Answer 4

the energy contained within a system that is responsible for its temperature

Question 5

elastic energy

Answer 5

energy stored in an object due to a force that temporarily changes its shape, such as squashing or stretching

Question 6

nuclear energy

Answer 6

a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons

Question 7

geothermal energy

Answer 7

heat energy from the earth

Question 8

sound energy

Answer 8

Sound energy is the energy that we create when sound waves move outward from a vibrating article or sound source.

Question 9

mechanical energy

Answer 9

sum of the kinetic energy, or energy of motion, and the potential energy, or energy stored in a system by reason of the position of its parts.

Question 10

hydroelectric energy

Answer 10

a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants.

Question 11

series circuits

Answer 11

all components are connected end-to-end to form a single path for current flow

Question 12

parallel circuits

Answer 12

comprises branches so that the current divides and only part of it flows through any branch.

Question 13

circuit basic components

Answer 13

power source, connector, load, control.

Question 14

Rube Goldberg Machine

Answer 14

chain reaction–type machine or contraption intentionally designed to perform a simple task in an indirect and overly complicated way.

Question 15

6 simple machines

Answer 15

pulley, lever, wheel, and axle, wedge, inclined plane, screw.

Question 16

pulley

Answer 16

a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim.

Question 17

lever

Answer 17

a simple machine made of a rigid beam and a fulcrum

Question 18

wheel and axle

Answer 18

The wheel and axle is a type of simple machine used to make tasks easier in terms of manipulating force by applying the concept of mechanical advantage

Question 19

inclined plane

Answer 19

consisting of a sloping surface, used for raising heavy bodies

Question 20

screw

Answer 20

a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force

Question 21

wedge

Answer 21

a simple machine used to separate two objects, or portions of objects, through the application of force

Question 22

power source

Answer 22

pushes the electricity through the circuit.

Question 23

connectors

Answer 23

connect all parts to create the path for electricity to travel through

Question 24

load

Answer 24

the thing that is being powered by the electricity in a circuit

Question 25

control

Answer 25

turns the power on or off (creates a closed or open circuit)
