a
frictional force
b
normal force
c
gravitational force
d
tension

Answer 1

For question 21, the correct answer is:

**a) frictional force** - This is an example of a contact force, as it arises from physical contact between surfaces.

For question 22, the correct answer is:

**c) gravitational force** - This is an example of a field force, as it acts at a distance without the need for direct physical contact.
