3. When sitting in a chair the chair exerts ____________________ force on you.

4.Pulling the dalda out of the dalta packet is an example of _______________ strength.

5. Magnetic force is an example of ____________ force.



​

Answer 1

Answer:

1. Force
2. Thrust
3. Upward
4. Frictional
5. Electromagnetic

Explanation:

1. A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.
2. The total force acting perpendicular on a given surface is called thrust. Thrust acting upon a unit area is called pressure.
3. When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces.
4. Frictional strength is governed by the resistance to shear of the large ensemble of discrete contacts that forms the interface that separates two sliding bodies. An interface's overall strength is determined by both the real contact area and the contacts' shear strength6,7.
5. The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.
