1 MS. MORGAN Force

2 What is a Force? Something that changes the state of rest or the state of motion of an object. Can be a…. push or a pull Unit of measurement: Newtons (N)

3 What is a Balanced Force? Forces that do not change the motion or direction of an object. Net Force is 0 Example: When a book is on a table the book is not moving because the force of the table pushing up is equal to the force of gravity pulling down.

4 What is an Unbalanced Force? Forces that change the state of motion or direction of an object. Net Force is not 0 Example: When a book is pushed off the table the book falls to the floor because the pull of gravity is greater than any upward push.

5 What is Friction? An unbalanced force that opposes motion between two surfaces.

6 Calculating Force Equation: Force = mass * acceleration (F = ma) Units of measurement:  Force = Newtons (N)  Mass = kilograms (kg)  Acceleration = Meters per second squared (m/s 2)

7 #1 F= _________ A= 32m/s2 M =5.4 KG #1 F= 32 * 5.4 = 172.8 N

8 A = 56 /5.4=10.3 m/s2 #2 F=56 N A= ___________ M =5.4 KG

9 #3 F=76 N A= 2m/s2 M =____________ M = 76 / 2 = 38 KG
