According to Newton's 3rd law, every force has an equal and opposite reaction force.
Therefore, the reaction force on an object, is the exact same force it applied on another object, with the reverse direction.
The force that pushes back on you when you push on something is called the reaction force. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, when you exert a force on an object, the object exerts an equal force in the opposite direction back on you.
Work is something that is done when a force moves an object over a distance.
Work is calculated as force multiplied by the distance the force is applied over. If the force is applied but the object does not move, no work is done because there is no displacement. So, it is possible to apply force without doing work if there is no movement of the object.
Work is done when a force is applied to an object, causing it to move in the direction of the force. Both force and displacement in the direction of the force are necessary for work to be done.
The idea of a reaction force comes from Newton's third law; "If object A exerts a force on object B ,then object B will exert an equal but opposite force back on A". In many problems some of the forces are considered as the "initiating" force or the applied force. When you consider a force as being applied, like a bulldoser pushing a rock, then the force which must act back , the rock pushing back on the doser, is called the reaction force. Sometimes you don't really have an initiating force but it still convienient to think of one force as the force of interest and the back force as the reaction force. There is no single formula for reaction force since it can apply to any force. For example, the earth attracts you with a force mg (your weight), then you can think of the reaction force as you attract the earth with a force -mg; equal but opposite.
Actually a force without another reaction force is something that will always be moving or staying motion because theres no reaction to stop it but theres no such thing as that so ya......
Force is but a reaction that is caused by the physical energy of something pushing and object.
The force that pushes back on you when you push on something is called the reaction force. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, when you exert a force on an object, the object exerts an equal force in the opposite direction back on you.
Work = force * distance moved
Work is something that is done when a force moves an object over a distance.
Reaction pairs work on the same things and in opposite directions.
-- When you catch a ball, you have to change its speed from something to nothing. -- That requires acceleration, and acceleration requires force. -- The force that changes the speed of the ball from something to nothing comes from the muscles in your catching arm.
When something exerts a force on an object, that object exerts an equal and opposite force on the other object.
prussure=force/area
Work is something that is done when a force moves an object over a distance.
When a force moves something parallel to the direction of that force, it is called work. Work is defined as the product of the force applied and the distance moved in the direction of that force. Conduction, on the other hand, refers to the transfer of heat through a material without the movement of the material itself.
input force/effort force In physics, the force that you apply to something over time is "work".
