Scientific method

Back 1

Ask a question, Research, Hypothesis,Experiment,Data,Resluts

Front 2

Dependent variable

Back 2

a variable (often denoted by y ) whose value depends on that of another.

Front 3

Independent variable

Back 3

a variable (often denoted by x ) whose variation does not depend on that of another.

Front 4

Constant

Back 4

occurring continuously over a period of time.

Front 5

Control

Back 5

the power to influence or direct people's behavior or the course of events.

Front 6

Volume

Back 6

The amount of space occupied by a three-dimensional object or region of space.

Front 7

Mass

Back 7

In physics, the property of matter that measures its resistance to acceleration.

Front 8

Density

Back 8

is a measure of mass per volume.

Front 9

Motion

Back 9

the action or process of moving or being moved

Front 10

Speed

Back 10

is a way of measuring how quickly something is moving or being done, or something moving fast.

Front 11

Displacement

Back 11

the state of being displaced or the amount or degree to which something is displaced.

Front 12

Velocity

Back 12

is a physical vector quantity; both magnitude and direction are needed to define it.

Front 13

Momentum

Back 13

the quantity of motion of a moving body, measured as a product of its mass and velocity

Front 14

Force

Back 14

strength or energy as an attribute of physical action or movement

Front 15

Friction

Back 15

the resistance that one surface or object encounters when moving over another.

Front 16

Gravity

Back 16

the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

Front 17

Weight

Back 17

a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

Front 18

Newton's 1st law

Back 18

A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force.

Front 19

Force

Back 19

strength or energy as an attribute of physical action or movement.

Front 20

Isotope

Back 20

each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

Front 21

Kinetic Energy

Back 21

energy that a body possesses by virtue of being in motion.

Front 22

Potential Energy

Back 22

the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

Front 23

Chemical Potential energy

Back 23

a thermodynamic function of a substance in a system that is the partial differential of the Gibbs function of the system with respect to the number of moles of the substance

Front 24

GPE

Back 24

is energy an object possesses because of its position in a gravitational field.

Front 25

Elastic Potential Energy

Back 25

is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape.Elastic energy occurs when objects are compressed and stretched, or generally deformed in any manner.

Front 26

Thermodynamics

Back 26

the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.

Front 27

Earth's Gravitational Force

Back 27

the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface.

Front 28

Sea Level

Back 28

the level of the sea's surface, used in reckoning the height of geographical features such as hills and as a barometric standard. 101KPA

Front 29

Pressure

Back 29

The force per unit area that one region of a gas, liquid, or solid exerts on another

Front 30

volume

Back 30

is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, teaspoons and ounces

Front 31

Allotrope

Back 31

each of two or more different physical forms in which an element can exist. Graphite, charcoal, and diamond are all allotropes of carbon.
