11. Which of the following is not a fundamental force?
a) frictional force
b) electromagnetic force
c) gravitational force
d) strong forces
e) weak forces
We can group forces into two types: contact forces and non-contact forces. Contact forces are seen between objects that touch each other whereas non-contact forces attract or repel without touch involved. Some problems involve both types of forces. Regardless of the types of forces involved, Newton's Laws still apply: F=ma (or F=0 when acceleration is zero). Match the forces to their formulas.
