Question

what is force ...
state its effect....
and name its types

Answer 1

definition: strength or energy as an attribute of physical action or movement.


The Effects of Forces. A force acting on an object may cause the object to change shape, to start moving, to stop moving, to accelerate or decelerate.

types:Frictional Force
Gravitational Force
Tension Force
Electrical Force
Normal Force
Magnetic Force
Air Resistance Force etc.

Answer 2

hiii!!!

here's ur answer...

FORCE - any push or pull given to an object is called force.

EFFECTS OF FORCE :-

1. change in shape and size.

2. change in position.

3. change in direction.

TYPES OF FORCES :-

>> contact force - these are the forces which take place when the two bodies are in contact with each other. for example : force between a football and foot of a player.

>> non contact force - these are the forces which comes into play without any contact between two bodies.

now, there are also different types of contact and non contact forces...

lemme tell about those :-

types of CONTACT FORCE :

=> muscular force - in this type of force action of the muscles in out body comes into play or another body. example : a man is pulling a bucket of water with full of water from the well uses muscular force.

=> frictional force - these force comes into when ever there is relative motion between 2 bodies. it always act in the direction opposite to the motion direction of motion. example : we are not able to walk if their is no friction on the ground. friction is useful as well as harmful to us.

types of NON CONTACT FORCE :

=> magnetic force - the force between a magnet and the object like ( iron, nickel, covold ) is called magnetic force. like poles repel each other and unlike poles attract each other.

=> gravitational force - the force of attraction between two bodies having mass.

A.=> R <=B.
(mass of body A)M1→M2
(mass of body B)
↓
force

FORCE=m1 × m2/R² R=distance b/w A and B

force of gravity - every body through upward is attracted towards the centre of earth called force of gravity.

=> electrostatic force - it is the force of interaction (repeltion or attraction). a charged body always attract uncharged body. there are two types of charged body - a positive charge (+ve) and negative charge (-ve). like charges repel each other and unlike charges attract each other.

hope it may help u..!!
