A Baseball is a great example of an internal force. The particles holding the baseball together is an internal force. But a baseball bat hitting the baseball is not an internal force, because an internal force is a force exerted by one part of a structure on another. The bat hitting the ball is an external force.
Another example is a car. The pistons pushing the rods, the axle pushing the wheels, the wheels moving the car...etc. All these things are internal forces working on the car because the these things are all inside the car. But the friction created by the wheels of the car on the ground is an external force, as is the force holding the car up. Hope this helps!

What happens to the centripetal force if the period is increased?
In circular motion the centripetal force is proportional to the speed squared. The speed is the circumference divided by the period. So if the period is increased the speed will decrease and the centripetal force will decrease. For example if the period is doubled then the speed is reduced by one half and the speed squared is reduced by one quarter, and so the centripetal force is reduced by one quarter.
Imagine that a group of people attack and defeat another group. Then the first group's leader becomes the ruler of the defeated group. This example best illustrates which theory?
This example best illustrates the theory of conquest as a mechanism for social change, where a dominant group imposes control over a weaker group through force.

What is the material that repels gravitational force?
There is no known material that can completely repel gravitational force. Gravitational force affects all matter and is a fundamental force of nature that cannot be blocked or neutralized by any material substance.
What is an example of and internal force?

What type of internal force acts on a wire as you make it into a circle?
the internal force is bending
Can an internal force cause acceleration in a body?
Yes, an internal force can cause acceleration in a body.
Is a torsion force an internal force?
Yes,torsion(Twist) is an internal force,along with tension(stretch),shear(cut,bend),compression(squeeze).An internal force acts between two parts of something.
What is an example of toal internal reflection?
periscope is an example of total internal reflection.
What are the 4 internal forces that act on structures and give one example for each?
The four internal forces that act on structures are tension, compression, shear, and torsion. Tension: This force stretches a material. Example: The cables in a suspension bridge experience tension forces. Compression: This force squeezes a material. Example: The columns in a building experience compression forces. Shear: This force causes parts of a material to slide past each other in opposite directions. Example: Cutting a piece of paper with scissors involves shear forces. Torsion: This force twists a material. Example: Twisting a wire involves torsion forces.
Internal forces?
A force internal to the system under consideration. Whether a force is regarded as internal or external depends on how the system is defined and classified, and is largely a matter of convenience. In biomechanics, the human body is generally regarded as the system and any force exerted by one part of the body on another is an internal force. Muscle contractions produce internal forces, which move a joint. Compare http://www.answers.com/topic/external-force.
What are the four internal forces?
The four internal forces are tension, compression, torsion, and shear. Tension is a stretching force, compression is a compressing force, torsion is a twisting force, and shear is a sliding force.
What types of forces act on structures?
external force and internal force
What is an internal force?
An internal force, in business management context, is an impacting factor on the business (be it favourable or otherwise) occuring/existing within the organization and controlling this factor is within the reach of an organization and not beyond it.
