Vector

A quantity that has MAGNITUDE and DIRECTION

Scalar

A quantity that has ONLY magnitude

Distance

The total length of the route an object travels when it moves.

Scalar

Scalar

Displacement

The change in position of an object

The moving of something from its place or position.

Includes DISTANCE and DIRECTION

Can be calculated on a velocity vs. time graph by finding the area between the line and the axes.

Vector

Speed

The rate at which an object is able to move or operate.

Scalar

= Distance/time

Scalar

= Distance/time

VELOCITY and DIRECTION

= Change in Velocity/time

= Vf - Vi/time

Position vs. Time Graph

Displays the position of an object over the course of time.

Slope

= Rise/Run

=y2 - y1/x2 - x1

Shows velocity on a Position vs. Time graph

= d/t = velocity

Reveals information about an objects acceleration on a Velocity vs. Time graph

= v/t = acceleration

=y2 - y1/x2 - x1

Shows velocity on a Position vs. Time graph

= d/t = velocity

Reveals information about an objects acceleration on a Velocity vs. Time graph

= v/t = acceleration

Velocity vs. Time Graph

Displays the velocity of an object over the course of time.

Positive velocity

Object is moving in a RIGHTWARD direction.

Line is within the positive region of the velocity vs. time graph (ABOVE the x-axis).

Line is within the positive region of the velocity vs. time graph (ABOVE the x-axis).

Negative velocity

Object is moving in a LEFTWARD direction.

Line is within the negative region of the velocity vs. time graph (BELOW the x-axis).

Line is within the negative region of the velocity vs. time graph (BELOW the x-axis).

Constant velocity

NO acceleration

Changing directions

The line crosses THROUGH the x-axis on a velocity vs. time graph.

Speeding up

Magnitude is getting LARGER on a velocity vs. time graph.

Line moving AWAY from x-axis (whether in positive or negative region).

Line moving AWAY from x-axis (whether in positive or negative region).

Slowing down

Magnitude is getting SMALLER on a velocity vs. time graph.

Line moving TOWARDS x-axis (whether in positive or negative region).

Line moving TOWARDS x-axis (whether in positive or negative region).
