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.
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
Yes, muscular force is an example of a contact force. It is the force applied by our muscles when they come into contact with an object to either push or pull it.
Adolf Hitler is an example of the force theory
The rain is an angry force is an example of a metaphor.

A ball just dropped is an example of free fall, where the only force acting on it is gravity causing it to accelerate downwards at a constant rate of 9.81 m/s^2.
An example of energy.
An example of impact force is when a hammer strikes a nail. The force of the hammer hitting the nail causes an impact that drives the nail into a surface.
"The" example does not exist, as there is no such things as "construtive" force. Here's an example you may like though. An example of correct spelling is "constructive."
