Sheet
Physics-The study of matter and energy and how they interact.
Net Force- The overall force on an object when all the individual
forces acting on it are added together.
Today’s to do list. . . . .
 Correct last nights homework..
 Finish notes
 Lab activity: Speed problems
Acceleration
 Acceleration- the rate at
which velocity changes
over time.
 An object accelerates if it
changes speed or direction.
Acceleration Formula
 Acceleration = Final Velocity- Initial(Starting ) Velocity
Time it takes to change speed
Calculate it
