physics

Question 1

gravitational

Answer 1

relating to movement toward a center of gravity.

Question 2

radiant

Answer 2

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

Question 3

chemical

Answer 3

Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.

Question 4

thermal

Answer 4

Thermal energy refers to the energy contained within a system that is responsible for its temperature.

Question 5

elastic

Answer 5

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object.

Question 6

nuclear

Answer 6

Nuclear energy is the energy in the nucleus, or core, of an atom

Question 7

geothermal

Answer 7

Geothermal energy is heat within the earth.

Question 8

sound

Answer 8

Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate.

Question 9

mechanical

Answer 9

Mechanical energy is produced by sourcing potential and kinetic energy and turning it into power.

Question 10

hydroelectric

Answer 10

is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity

Question 11

series circuits

Answer 11

A series circuit comprises a path along which the whole current flows through each component.

Question 12

parallel

Answer 12

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

Question 13

Question 15

load

Answer 15

obeject that recives the power

Question 16

control

Answer 16

on and off switch

Question 17

pulley

Answer 17

a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used

Question 18

lever

Answer 18

a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.

Question 19

wheel and axle

Answer 19

a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.

Question 20

wedge

Answer 20

a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.

Question 21

inclined plane

Answer 21

a plane inclined at an angle to the horizontal.
a sloping ramp up which heavy loads can be raised by ropes or chains.

Question 22

screw

Answer 22

a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.
