What is force??
Explain it
Answers
Answer:
In physics, a force is any influence that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, 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.
A force is an effort that changes the state of an object at rest or at motion.
It can change an object's direction and velocity.
Force can also change the shape of an object.

✦ Normal force :
The normal force is the force that surfaces exert to prevent solid objects from passing through each other.
✦ Applied force :
An applied force is a force that is applied to an object by a person or another object.
✦ Frictional force :
Frictional force refers to the force generated by two surfaces that contacts and slide against each other.
✦ Tension force :
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides.
✦ Spring force :
The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it.
✦ Resisting force :
Resistive force is a force, or the vector sum of numerous forces, whose direction is opposite to the motion of a body.
