Fp


Fz


FN


Ff


FD


Fg

Answer 1

Answer : The forces used in force diagrams are
`F_z`,
`F_f` and
`F_g`.

Explanation :

The push or the pull applied on an object is called force. It is denoted by F. There are some notation for the different types of forces.

`F_z` is the force acting in z- direction.

`F_f` is the frictional forces. It is the opposing force. It opposes the motion of an object.

`F_g` is the gravitational force.

So, the correct options are
`F_z`,
`F_f` and
`F_g`

Answer 2

The notation that are commonly used on force diagrams to show forces acting on an object are put marked, check image.

These are force is z-direction,
Force due to gravity,
Frictional force.
