What do you think affects the force of friction? Objective:
Objective: To build an understanding of the force of friction.
Success criteria: Understand the variables that make up friction. Discovery Lab:
Force of friction List the possible variables that make up the force of friction
Using the force probe and friction block, test each variable.
Data: 1. Variable 1:
b) How are you testing it
What was your result 2. Variable 2 :
….Etc… What did we find out:
What did we find out: Force of friction
Force of friction Static Force of Friction – Force needed to start an object moving Kinetic Force of Friction – Force needed to keep an object moving Ff=µFn
Force of static friction uses µstatic – The force it takes to get something moving Force of kinetic frictio...
