types of forces

2. Supporting force exerted on an object in contact with a surface (always drawn perpendicular to the surface on which the object is resting).
3. strength or energy as an attribute of physical action or movement.
7. Upward force exerted on an object submerged in a fluid caused by difference in force on top and on bottom of a submerged object and equal to the weight of the fluid displaced by the object.
10. Force that acts at a right angle to the direction of motion of an object through air. Lift is created by differences in air pressure.
11. Downward force of gravity acting on an object (represents the weight of the object). **
12. Caused by repulsion between atoms/molecules as an object is compressed (similar but opposite to tension force)

1. Opposing force caused by irregularities and chemical bonds between surfaces moving past each other.
4. Force caused by excess electrical charge.
5. Caused by an object pushing air out of the way. Sometimes called air resistance.
6. Force applied on an object by a living person, animal, another object, etc.
8. Caused by attraction of atoms/molecules within a stretched rope or string.
9. Force due to charged objects moving in a magnetic field.
