Question

What is force? Explain the two types of forces with proper explanation.

Answer 1

Hello friend,

Here we will discuss everything one by one-

Force- A force is an influence which changes or tends to change the state of rest or of uniform motion,direction of motion, shape or size of a body.

Effects of force's-

•Force may move a body at rest.
•Force may stop a moving body.
•Force can change speed of a moving body.
•Force can change direction of a body.
•Force can change shape and size of a body.

Forces are of two types-

•Balanced forces- If a number of forces are acting on a body and the body doesn't move, then the forces are said to be balanced forces
The resultant of any number of forces acting on a body is 0. Example- In a tug of war game, the two teams pulling string from opposite direction with equal forces , so that there no motion, the forces are said to be balanced forces.

•Unbalanced forces- If the resultant of forces acting on a body is non-zero, the state of rest or motion of the body changes, such forces are called unbalanced forces. For example- In a tug of war game, the two teams pulling string from opposite direction exert forces F1 and F2 such that F1 > F2, the the string will be pulled towards one side where the forces will be more.Such forces are called unbalanced forces.


Hope it helps...!!!!

Answer 2

" $\ \ \ \ \ \huge \mathfrak{ \pmb{ \colorbox{lavender}{ \: \: \: \: \: \: \red F \: \blue O \: \green R \: \purple C \: \orange E \: \ \ \ \ \: }}}$ "

• Force is push or pull acting on a body which tends to change its state of rest or of motion. It is denoted by "F". It has a magnitude and a direction.

$\large \red{\bold{Formula \ for \ Force \: : - } }$

$\huge\underline{\boxed{\textrm{F = {\texttt{ma}}}}}$

Here,

• " m " = Mass of the body
• " a " = Acceleration
• " F " = Force

________________

Unit of Force :-

• SI unit of force is Newton(N).
• C.G.S (centimetre gram second) unit of force is Dyne.

Effects of force -

• Force can change the direction of a moving object.
• Force can change the shape and size of an object.
• Force can change the speed of a moving object.
• Force can change a body′s state of motion or rest.
