In physics, a force is an action (usually a push or a pull) that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. In mechanics, force makes ideas like ' pushing' or ' pulling' mathematically precise.
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. Because force has both magnitude and direction, it is a vector quantity.
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.
