Physics Unit 2 Review of Motion

What are the 6 ways we have of describing motion?

Written description

Motion maps

Data table

Position vs Time graphs

Velocity vs. time graphs

Equations

What is needed in a written description of Motion

At what location does it starts

If moving, state

If motionless, state

What is needed in a motion map

Place a dot for every second the object is moving

First dot should also write “start”

If motionless, the dot has no arrow

At the last location, write “end”

How is a data table set up

Easiest way to understand motion

Your independent variable is time (s)

• Time should always start at t=0

Your dependent variable is position (m)

• can start position at any value

What is needed in a graph of position vs time

x-axis→ time

y-axis → positon

If the object is moving, then the slope shows velocity

If the object is stationary, then v=0

What is needed in a graph of velocity vs time

x-axis→ time

y-axis → velocity

If the object is moving, then the y-value shows the velocity

If the object is stationary then y=0
