Distance calculator f5/7/2023 If they are very far apart then the force is weaker. The equation says that if two objects are very heavy then there is a strong force between them because of gravity. It is also used to calculate how other planets, stars and objects in space move around. This equation is used to calculate how the earth moves around the sun and how the moon moves around the earth. How to enter numbers: Enter any integer, decimal or fraction. Newton's Second Law Īccording to Newton's Second Law of Motion, the formula for finding force is: Distance Calc Distance Formula Calculator Enter any Number into this free calculator How it works: Just type numbers into the boxes below and the calculator will automatically calculate the distance between those 2 points. There are four fundamental forces in physics.Ī force is always a push, pull, or a twist, and it affects objects by pushing them up, pulling them down, pushing them to a side, or by changing their motion or shape in some other way. The strength of a force is measured in Newtons ( N). Forces cause objects to accelerate, add to the object's overall pressure, change direction, or change shape. For example, a force causes an affected object to be pushed or pulled in a certain direction. Gravity and electromagnetic force are two examples of forces.Ī force changes the state of an object (some physical quantity changes) or, strictly, the states of two objects, since the force is an interaction. Another example is electromagnetic force, which acts between objects with charge, like an electron and the nucleus of an atom. For example, gravity acts between objects with mass, like the sun and the earth. Different forces act between different sorts of object. The objects are just the things the force acts between. This idea is known as Newton's third law, where action and reaction are "equal and opposite" ( matched). It is called an interaction because if one object acts on another, its action is matched by a reaction from the other object. In physics, a force is a push or pull between objects.
