what is the connection between force and energy?

Bigger pushes and pulls cause bigger changes in an object's motion or shape. When objects collide, contact forces transfer energy so as to change the objects' motions. When two objects interact, each one exerts a force on the other, and these forces can transfer energy between them.

The law of conservation of energy states that for any system, energy cannot be created or destroyed; it can only change from one form to another or transfer from one object to another. ... Mechanical energy comes in two forms: potential energy, which is stored energy, and kinetic energy, which is energy of motion.

When two objects interacting through a force field change relative position, the energy stored in the force field is changed. Each force between the two interacting objects acts in the direction such that motion in that direction would reduce the energy in the force field between the objects.

When force is applied on an object, resulting in the movement of that object, work is said to be done. Work can be calculated using the formula, Work done is equal to Force into Distance. The ability or the capacity to do work is called energy.

There is a relation between charge and force. According to Coulomb's law, the magnitude of electrostatic force of attraction between two point charges is directly proportional to product of magnitudes of charges and inversely proportional to the square of the distance between them.

Relation bewteen KE and W: The work done on an object by a net force equals the change in kinetic energy of the object: W = KEf - KEi. This relationship is called the work-energy theorem.

The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. ... Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.

The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.

When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object. For example, when energy is transferred to an Earth-object system as an object is raised, the gravitational field energy of the system increases.

Potential Energy is the energy stored in a system when work is done on it by some external agency. Potential is just the work done per unit something of that system e.g. electric potential is just work done per unit charge. Similarly,gravitational potential is work done per unit mass.

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. ... Forces only exist as a result of an interaction.

It has previously been mentioned that there is a relationship between work and mechanical energy change. ... If only internal forces are doing work (no work done by external forces), then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be conserved.

Force and work are directly proportional to each other, while force and displacement are indirectly propotional. The equation showing the relationship is W= Fd. W represents work measured in joules; F represents force in newtons; and d represents distance in meters.

In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces, the mechanical energy is constant.

There is a significant difference between work and energy. Work is the transferring of an amount of energy with the help of a force covering a particular distance through a direction. Energy is also referred to the force which works in a certain distance. These both can be termed as scalar units.

the Big idea: Force and motion are fundamental to all matter in the universe. A force is anything that can push or pull on an object. Forces influence objects that are at rest or that are already in motion. Isaac Newton's three laws of motion involve inertia, mass, velocity, and momentum.

What is the difference between force and pressure? Force is a push or a pull and is the cause of acceleration. Pressure is the amount of force per unit of area (the smaller the area supporting a given force, the greater the pressure on that surface).
