What is force ?
- Force is defined as a push or pull.
- It is calculated as :
Force = Mass × Acceleration.
- It is denoted by F.
- F = kg × ms^-2
- It's SI unit is kg ms^-2 or N ( Newton ).
The effects of force are as follows :-
1) The force can bring an object into motion. For example :- kicking a football makes it to come into motion.
2) The force can bring an object to rest. For example : - Friction b/w the ground and the football stops the football after some distance.
3)Force can change shape & size of an object .
For example :- When we press sponge, it's shape changes. Similar is the case of a string.
