Front 1

Reference point

Back 1

is the starting point you choose to describe the location, or position of an object

Front 2

Position

Back 2

is an object's distance and direction from a reference point

Front 3

Relative

Back 3

compared (to)

Front 4

Specify

Back 4

to indicate or identifyDimension

Front 5

Dimension

Back 5

distance or length measured in one direction

Front 6

Motion

Back 6

is the process of changing position

Front 7

Displacement

Back 7

is the difference between the initial (first) position and the final position of an object

• So if you make a home run the displacement is 0, but if you run to first the displacement is the distance from home to First base.
  

Front 8

Motion

Back 8

from Latin means to move

Front 9

Speed

Back 9

is a measure of the distance an object travels per unit of time

Front 10

Constant speed

Back 10

is the rate of change of position in which the same distance is traveled each second

Front 11

Instantaneous speed

Back 11

is speed at a specific instant in time

Front 12

Average Speed

Back 12

is the total distance traveled divided by the total time taken to travel that distance

AS = TD(Measure in m)/TT(measured in s)

symbol = v(with a line over it)

Front 13

Velocity

Back 13

is the speed and the direction of a moving object

Front 14

Acceleration

Back 14

is a measure of the change in velocity during a period of time.

• an object accelerates when its velocity changes
  

Front 15

average accelerations

Back 15

A change in velocity during a time interval divided by the time interval during which the velocity changes

acceleration(in m/s^2) -

total time (in s)

a = Vf-Fi

t

Front 16

Average Accelerations

Back 16

If a body is having an initial velocity vi at time interval ti and it attains final velocity vf after some time tf then its average acceleration formula is given by

• Where,vi is the initial velocity,
• vf is the final velocity,
• ti is the initial time,
• tf is the final time.
