When you jump you will return to the surface due to gravity or when you throw something up to the highest point it will return to the surface, because of gravitational force.

When we close the fridge door, the door closes because of the magnetic force or the magnetic attraction force pulling the door and forcing it to close. The fridge has strong magnets hiding inside which is why magnetic force works on fridges, but if it weren't for the strong magnets then there wouldn't be magnetic force.

When you are stopping a ball from hitting you with your hands, the surface of your hand and the surface of the ball touches each other and it stops due to frictional force.

When using compasses the magnetic needle always points to north, this is because compasses have the magnetic needle installed on a pivot. The needle in the compass will now have a free reign to spin at will because of magnetic force.

Whenever we bump into the walls, we get a reaction of pain in our bones cause of the force.

Example 2:

When we untie a ballon it lets out all the air in there and it flies around, thats because it lets the air out with force.

Example 2

When you walk at a natural speed, the swing leg use the muscle forces it to move your leg and relaxes immediately, and allowing the force of gravity to move it to the ground.

Example 2:

When you are applying brakes to stop a vehicle it also stops due to frictional force.

Example 3

Trains also use magnetic force to move at high speeds. There are 2 sets of strong magnets that are used to propel the train, one of the magnets is used to repel it above the tracks the other one is used to move the train foward.
