Motion In One Dimension

Front 1

is defined as the change of position of an object in a specific span of time relative to an observer. It also requires position and time.

Back 1

Motion

Front 2

It is a quantity that describes when an event took place. It is a necessary parameter to describe and to observe changes in a specific space.

Back 2

• Time

Front 3

It describes how far an obiect has traveled. It also pertains to the total length travelled by an object in motion. is always greater than or equal to displacement.

Back 3

Distance

Front 4

it is the length and direction of the line that connects the initial position to the final position. It describes how 'far an object is from its initial position.

Back 4

Displacement

Front 5

it is the rate of change in position. It can be noted as v or s and has a unit of m/s or ms-1.

Back 5

Speed

Front 6

Describes how fast an object is changing its position within a span of time

Back 6

speed

Front 7

it is the rate of change in position with respect to a reference point.

Back 7

Velocity

Front 8

It describes how an object changes its velocity per elapsed time.

It is a vector quantity with an SI unit of m/s2.

Back 8

ACCELERATION

Front 9

T hree ways to say that an object is accelerating:

Back 9

if the magnitude of the velocity of the object

is changing;

• if the direction of the motion of the object is

changing; and

• if both the magnitude of the velocity and the

direction of motion are changing.

Front 10

a and v are of the

same direction ⟶ speeding up

Back 10

positive acceleration

Front 11

(deceleration) ⟶ a

and v have opposite directions ⟶ slowing

down

Back 11

Negative acceleration

Front 12

object is traveling at

constant v or not moving at all

Back 12

Zero acceleration

Front 13

It is a kind of motion along a straight line with constant acceleration.

It means that the velocity of an object changes at a fixed rate during the entire course of the motion.
