plsssssssssssssss



answer​

Answer 1

In physics, a force is any interaction 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.

Other units: dyne, pound-force, poundal, kip, kilopond

In SI base units: kg·m/s2

SI unit: Newton

Answer 2

Question-

What is force ?

Force -

✴Force is the push or pull that changes or tends to change the shape and size of an object

✴SI unit of force = Newton (N)

✴CGS unit of force = Dyne

✴Force = Acceleration × Mass

✴Force is a vector quantity.

✴Other units = kgf , gf

✴Types of force => Non contact force

=> contact force

✴Examples of force which can change

●direction

●speed

●shape

===> Frictional force

===> Muscular force

===> Mechanical force

===> Gravitational Force

===> Electrostatic Force
