What is the formula for the maximum friction??
$$ F_\text{max} = \mu R $$
What is $\mu$ when talking about friction??
The coefficient of friction.
What is $\mu$ if a surface is described as “smooth”??
$$ 0 $$
If a block is being pushed with a $10\text{N}$ force but there is a $20\text{N}$ max friction, what will happen??
The block will not move.
What is the situation called when a block is being pushed with a $20\text{N}$ force but there is a $20\text{N}$ max friction??
A limiting equilibrium, the block will not move.
If a block is being pushed with a $30\text{N}$ force but there is a $20\text{N}$ max friction, what will happen??
The block will move with a $10\text{N}$ force.
