What are
some factors
that affect
friction
Friction depends
mainly on 2 things
What direction
would the force of
friction be in?
Friction is simple
𝐹𝑓 = 𝜇𝐹𝑛
𝜇 is the coefficient
of friction
• The coefficient of friction is
different for all materials and
surfaces.
• Has no units
Susan is trying to push a 12kg crate across the floor.
She observes that the force of friction between the
crate and the floor is −50N.
What is the coefficient of static friction?
