what is force?how many types of Forces?
Answers
Answer:
Push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. Terms like stretch and squeeze can also be used to denote force.
In Physics, force is defined as:
The push or pull on an object with mass that causes it to change its velocity.
There are six kinds of forces that act on objects when they come into contact with one another: Normal force, applied force, frictional force, tension force, spring force and resisting force. These forces make objects change their motion or movement , the act of going from one place to another.
The Force can be measured using a spring balance. The SI unit of force is Newton(N).
Common symbols: F→, F
SI unit: Newton
In SI base units: kg·m/s2
Other units: dyne, poundal, pound-force, kip, kilo pond
Derivations from other quantities: F = m a
Dimension: LMT-2
