Has different theories about gravity and forces

Question

June 13, 2010

Hi Ron Kurtus,

Your page states: Force at a distance is strange.

That's because it doesn't really exist. Gravity is a pushing force of Mass Expansion. It does not "pull" through empty space.

Answer

Gravity has been defined as a force at a distance, as caused by a curvature in space and as an exchange or graviton particles. Your concept of gravity being a force of mass expansion is interesting, but I am not sure it is accepted by most scientists.

Electrical and magnetic forces also act at a distance, but I am not sure how they fit in your theory.

You need to be more distinct in your statements. For example, gravity is not 9.8 m/s^2. That number should be stated as the "acceleration due to gravity". This should help clarify your concepts.

Want examples about static force

Question

Answer

See "Static Electricity Forces" at:
http://www.school-for-champions.com/science/static_forces.htm

However, if you are talking about a static force where something is not moving, see http://www.school-for-champions.com/science/friction.htm

What are the effects of forces?

Question

August 30, 2009

could you please describe the effects of forces? with their examples???

Answer

A simple explanation of a force is that it is a push or a pull. When you push on a door, you are exerting a force on the door. The wind can exert force on a boat, causing it to move. Gravity is a force that pulls you toward the ground.
