Front 1

Mechanics

Back 1

Study of the motion of mechanic branch objects

Front 2

Kinematics

Back 2

The science of describing motion of objects using words, diagrams, graphs, numbers, & equations.

Front 3

Vector

Back 3

Quantities that are fully described by both a magnitude & a direction

Front 4

Scalars

Back 4

Quantities that are fully described by a magnitude alone

Front 5

Distance

Back 5

scalar quantity; refers to "how much ground an object has covered" during its motion.

Front 6

Displacement

Back 6

vector quantity; "how far out of place an object is"; objects overall change in position.

Front 7

Speed

Back 7

Scalar quantity; "how fast an object is moving"
The rate at which an object covers distance

Front 8

Velocity

Back 8

vector quantity; "that rate at which an object changes a position"

Front 9

Average speed formula

Back 9

D/T

Front 10

Average velocity formula

Back 10

P/T = Displacemnet/T

Front 11

Instantaneous Speed

Back 11

Speed at any given instant in time

Front 12

Acceleration

Back 12

vector quantity;
Happens when an object:
-speeds up
-slow down
-changes direction

Front 13

Balance Force

Back 13

Forces on an object are equal in size but opposite in direction

Front 14

Net Force

Back 14

Sum of all forces on an object

Front 15

Unbalanced Force

Back 15

Forces on an object are not equal & opposite direction

Front 16

Applied Force

Back 16

A force applied to an object by a person or another object
Fapp

Front 17

Gravity Force

Back 17

Force with which the earth, moon, or other massively large object attracts another object towards it; weight of an object
Fgrav

Front 18

Normal Force

Back 18

Support force exerted upon an object that is in contact with another stable object
Fnorm

Front 19

Friction Force

Back 19

Force exerted by a surface as an object moves across it or makes an effort to move across it
Ffric

Front 20

Air Resistance Force

Back 20

Special type of frictional force that acts upon objects as they travel through the air
Fair

Front 21

Tension Force

Back 21

Force that is transmitted through a string, rope, cable or, wire when it is pulled tight by forces acting from opposite ends
Ftens

Front 22

Spring Force

Back 22

Force exerted by a compressed or stretched spring upon an object that is attached to it
Fspring

Front 23

Free Body Diagrams

Back 23

arrows reflects the magnitude of the force & the direction of the arrow shows the direction of the force

Front 24

Newton's 1st Law/ Law of Inertia

Back 24

An object at rest tends to stay at rest & an object in motion tends to stay in motion with the same speed & in the same direction unless acted upon by an unbalanced force
