A normal force is a force perpendicular to something - for example, to a surface. This force can be supplied by just about anything; in many cases by gravity.A normal force is a force perpendicular to something - for example, to a surface.

No. Gravitational force is the attractive force that objects of mass have on other matter (including light). Pushing a grocery cart is an example of force, just not a gravitational force. Now, dropping a grocery cart would be an example of gravitational force, since it is the Earth's mass that is attracting it towards the ground.
Yes . It is an example for contact force.
A launched projectile is not an example of centrifugal force. It is an example of centripetal force.
Pull or push is an example of force
Adolf Hitler is an example of the force theory
Frictional force.
The rain is an angry force is an example of a metaphor.
"His anger is a gale force" is an example of a simile, as it compares his anger to the intensity and power of a strong wind.

Generally it is just called an unbalanced force. A net force is the result of one or more unbalanced forces and results in an acceleration. An example of an unbalanced force is the force of gravity.(which is the answer to a typical quiz question)
