force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton ’s three laws of motion set forth in his Principia Mathematica (1687).
Learn the different types of forces in physics and mechanics, along with examples and diagrams. What is the equation for force. What are the effects of force.
Force is push or pull. Unbalanced forces make an object accelerate. Forces on an object are usually balanced: forces in one direction are equal to forces in the opposite direction: No acceleration. Example: The forces are in balance at the top of this bridge tower.
