unit 3- Speed

[7.7A] calculate average speed using distance and time measurements from investigations;

Unit 3 - Speed

[7.7B] distinguish between speed and velocity in linear motion in terms of distance, displacement, and direction;

displacement

direction

velocity

uniform motion

distance

speed

linear motion

time

reference point

GUIDING QUESTIONS...

Graphing

What is the difference between speed and velocity? What variables can be found on a distance vs time graph?

Displacement

The length of a straight line between two points

Distance

Measurement from one point to another point

Reference Point

A place or object used for comparison to determine if an object is in motion.

Speed

The distance an object travels per unit of time.

Examples

S = d/t

Examples

Velocity

Speed in a specific direction.

Uniform Motion

the movement of an object along a straight line at a constant speed

Time

Measurement of an interval from one event to another event

Direction

the path of a moving object using cardinal directions like north, south, east, west

Linear Motion

When an object moves in a straight line
