Pataasin ang iyong marka sa homework at exams ngayon gamit ang Quizwiz!

in 2 dimensions anything above the origins is considered positive and below is negative

...-

distance

a scalar quantity that is the length of travel, neglecting direction

speed

a scalar quantity that measure how fast something moves, neglecting direction

magnitude

a term given to the size of quantity

velocity

a vector quantity that measures how fast something moves from one point to another with direction

free fall

an object in free fall at constant acceleration towards the surface of a planet neglecting air resistance

average velocity equation

change in position / change in time so final position - initial position / final time -initial time

average acceleration formula

change in velocity/ change in time so final velocity - initial velocity / final time - initial time

displacement equation

displacement= final position - initial position

average velocity

is equal to the displacement divided by the time during which the displacement occured

What is the SI unit for distance and displacement?

meters (m)

SI unit of velocity

meters/ second (m/s)

anything to the left of the origin will be considered...

negative

anything to the right of the origin is considered .....

positive

distance is a __________ quantity

scalar

average acceleration

the average change in velocity divided by the change in time

displacement

the change in position of an object from one point to another in a straight line with direction

instantaneous position

the location of an object at a particular instant in time relative to the origin

position

the location of an object relative to the origin

acceleration

the quantity that describes the rate of change of velocity in a given time interval

instantaneous velocity

the speed and direction of an object at a single instant moment in time

origin

the zero point or where an object begins motion

displacement is a _________ quantity

vector

in displacement horizontal movement is denoted as ...

Δx

in displacement vertical movement is denoted as

Δy
