1. The force exerted when twisting wet clothes to squeeze out water is called muscular force. So, it is a type of contact force because muscular force can only be exerted on physical contact.
2. When slicing watermelon using a knife, there is a frictional force increase as cutting proceeds.
3. There is a muscular force applied when kneading a dough. So, it is also a type of contact force because muscular force can only be exerted on physical contact.
4. If a person is pushing a table across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the table by the person.
5. As shown in the photo, there is a tension force that is being transmitted through the rope when it is pulled tight by force acting from the opposite end.
