Newton's second law of motion states that force is equal to mass times acceleration, or F = ma. So, if a force is exerted on something that has mass, it will accelerate.
there will be always a reaction force
There's always a reaction force
The object through which the force is exerted must also change.
The object through which the force is exerted must also change.
a smaller force is exerted over a longer distance
The object is moved and energy is transferred.
right
there is a force exerted on each object of equal yet opposite sign and direction
They deform, first elastically then plastically.
Pressure is the force exerted on an object divided by the area where the pressure was applied.
Pressure depends on the quantity of force exerted and the area over which the force is exerted
