what is the application of force in our daily life?

 Forces are very important in all aspects of daily life:

The force of up-thrust helps to keep objects floating.

Friction and air resistance help to slow down and/or prevent us from slipping.
However low friction is useful too as it allows us to do certain activities such as ice-skating.
Air resistance can also be useful for example we can use it to our advantage in activities such as sky-diving.

Gravity is very important as this is the only reason that we are able to stay on the surface of the planet without floating off into space.

Spring force is used in every day objects such as mattresses to make them more comfortable.

Tension force is often used in certain objects such as hammocks and in activities such as tightrope walking.

Applied force is the force which is returned when we lean on an object or even just stand up. This force prevents us from falling through the floor of desk etc. etc.

hope this helps!

every thing we do is a result of some force
