what is a force ?and what it is work

Answer 1

Hey mate, here is your answer.: -)

__________________________

✅A force is any interaction that, when unopposed, will change the motion of an object...

✅A force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force...

Answer 2

In physics, a force is any interaction that, when unopposed, will change the motion of an object.[1] A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.

The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
