What happens to the friction force when the block tries to slide up the wall?

• It acts in the opposite direction

• It increases

• It remains constant

• It decreases

What is a potential issue when the coefficient of friction is large for a given angle?

• The block will not move up regardless of the push force

• The block will slide down

• The block will fall off the wall

• The block will rotate

How does a large coefficient of friction affect the denominator in the equation for push force?
