moving in the - direction and speeding up (getting faster)

If the area under the line forms a triangle then use

.5 times base times height

Formula to determine acceleration for velocity time graph

A= change in velocity/ time final velocity minus initial velocity divided by final time minus initial time A=slope

Velocity time graph: negative velocity means

Negative velocity means the object is moving in the negative direction; an object is moving in the negative direction if the line is located in the negative region of the graph(whether it's sloping up or down)

On a velocity-time graph the direction of motion is...

Not as obvious Since velocity is a vector the direction of motion will have the same sign as the velocity

velocity-time graph: a negative velocity means the object is moving in the...

in the negative direction; an object is moving in the negative direction if the line is located in the negative region of the graph (whether it is sloping up or sloping down) (have negative velocity if they're in the negative region)

Moving in the + direction and speeding up (getting faster)

+

moving in the - direction and slowing down (getting slower)

+

if they're opposites postion-time grap

+,- they're opposites, so it means they're getting slower(start fast or high on y axis and then the line gets lower because it's slowing down.

Moving in the + direction and slowing down (getting slower)

Using a position-time graph the direction of motion is...

Apparent

If the area under the line forms a rectangle then use

Base times height

on a velocity-time graph the line does not...

CURVE

velocity-time graph: If the acceleration is negative, then...

If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).

velocity-time graph: If the acceleration is positive, then...

If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

If the area under the line forms a trapezoid then use

Make it into a rectangle(base times height) and triangle(.5 times base times height) and add the two areas together

Velocity time graph a positive velocity means

Positive velocity means the object is moving in the positive direction; an object is moving in the positive direction if the line is located in the positive region of the graph(whether it's sloping up or down)

Velocity time graph the area bound by the line and aces represents

Represents the displacement of the object during that interval

Velocity time graph speeding up means...

Speeding up means that the magnitude (or numerical value) of the velocity is getting large. Therefore an object is speeding up if the line on a velocity time graph is changing from near the 0-velocity to a location further away from the 0-velocity point That is if the line if getting further away from the x-axis (the 0-velocity point) then the object is speeding up. And conversely if the line is approaching the x-axis then the object is slowing down

what does the slope of the line on a velocity-time graph reveal useful information about

The slope of the line on a velocity-time graph reveals useful information about the acceleration of the object.

Formula for position time graph to find the velocity

V= change in d/change in t. D2-d1/t2-t1 V=slope

on a position-time graph, the direction of motion is..

apparent

position-time graph: if the velocity is changing then...

if the velocity is changing then the slope is changing (a curved line)

position-time graph: if the velocity is constant then...

if the velocity is constant, then the slope is constant(a straight line)

position-time graph: if the velocity is positive then...

if the velocity is positive then the slope is positive (moving upwards and to the right)

on a velocity-time graph, the direction of motion is...

not as obvious. since velocity is a vector, the direction of the motion will have the same sign as the velocity

velocity-time graph: a positive velocity means the object is moving in the..

positive direction; an object is moving in the positive direction if the line is located in the positive region of the graph (whether it is sloping up or down) (has positive velocity if its in the positive region even if it's sloping down)

velocity formula

speed of something in a given direction displacement/time elapsed df-di/tf-ti

what does the slope of the line on a position-time graph reveal information about

the slope of the line on a position-time graph reveals useful information about the velocity of the object
