Energy is sort of the 'result' of forces.
For example, you want to pull a wooden block across the floor. There are a few forces opposing motion, like friction. When the block moves, you are actually exerting forces on it. Where and how can you get the energy to do that? It is from the food you eat, and the muscles in your body.
Also, the effort or amount of energyneeded to exert a force can be changed by simple machines such as levers and pulleys.

What is the difference between force and stress?
Force = Mass x Acceleration Stress = Force / Cross Sectional Area
What is the difference between a structure that is rigid and one that is flexible?
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.
What is difference between generator and oscillator?
A generator is used to convert mechanical energy to electrical energy. An oscillator is used to convert dc to ac
What are the differences and similarities between matter and energy?
Friction and cohesiveness are the only differences. The matter has stronger potential energy with stronger cohesive forces and the energy has stronger kinetic energy with demonstration as frictional force.
Whats the difference between biomass pyramid and energy pyramid and number pyramid?
== == Of the trophic levels of the ecological pyramid, there are three ways to describe the flow of energy in food chains. Numbers, energy and biomass. See the related link for more information.
What happens to the rate pf energy transfer between an object and its surroundings if the temperature difference between them is reduced?
If the temperature difference between an object and its surroundings is reduced, the rate of energy transfer between them will also decrease. This is because the driving force for heat transfer is smaller when the temperature difference is smaller.
Differentiate between potential difference and electro motive force?
Potential difference is the difference in electric potential energy between two points in a circuit. It is measured in volts and represents the work done in moving a unit charge across the points. Electro motive force (EMF) is the energy per unit charge supplied by a source, like a battery or generator, to move charge around a circuit. It is also measured in volts and represents the energy input provided by the source.
What is The difference between a Strike Team and a Task Force is?

What is the difference between the input force and output force?
The difference between and input force and an output force is that an output force is force exerted by a machine, and an input force is force exerted on a machine.
What is the difference between gravitational potential energy and gravitational force?
Gravitational potential energy is the energy stored in an object due to its position in a gravitational field, while gravitational force is the force of attraction between two objects due to their masses. Gravitational potential energy is related to the height of an object, while gravitational force depends on the masses of the objects and the distance between them.
What is the difference between force and conservation of energy?
Force is a vector quantity that describes the interaction between objects that causes a change in their motion, while conservation of energy is a principle stating that the total energy in a closed system remains constant over time. In other words, force is the cause of motion, while conservation of energy describes the effects of forces on a system's energy.
What is the difference between effort force and resistance force?
by the negative force and the positive force
What is the difference between thrust and pressure-?
what is the difference between thrust and pressure?
What is the difference between elastic force and elastic potential energy?
Elastic force is the force exerted by a stretched or compressed elastic material to return to its original shape. Elastic potential energy is the energy stored in an elastic material when it is stretched or compressed. The elastic force is responsible for restoring the material to its original shape, converting the stored elastic potential energy back to kinetic energy.
What is the difference between heat and pressure?
Heat is the transfer of thermal energy between objects due to a temperature difference, while pressure is the force exerted on a surface per unit area. Heat can increase the internal energy of a system, while pressure can change the volume or shape of a system.
What is the source of the large amount of energy evolved in nuclear fission?
It is basically the difference in energy between the original nucleus (u-235 or Pu-239) and the two smaller nuclei formed in the fission process. This arises because of the forces between the protons and neutrons, the strong nuclear force, and the electrostatic repulsion between protons. In effect the difference in mass is converted to energy.
What is the difference between electrical potential and electromotive force?
Electrical potential refers to the electric potential energy per unit charge at a point in an electric field, measured in volts. Electromotive force (emf) is the energy per unit charge supplied by a source of electrical energy, such as a battery, to drive current through a circuit, also measured in volts. Essentially, electrical potential is a property of a point in the field, while emf is the force that drives the flow of charge.
