Types of Forces

2. Caused by an object pushing air out of the way. Sometimes called air resistance
3. 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
6. Force that touches the apply a force
11. Force exerted by material when it's compressed, stretched, or deformed. Has a spring-like behavior
14. Forces in opposite directions that are not equal
15. Forces that are equal if both directions
18. Force that acts within the atomic nucleus. It holds protons and neutrons together, maintaaining the stability of atoms
19. Caused by repulsion between atoms/molecules as an object is comrpessed (similar but opposite to tension force)
20. Opposing force caused by irregularities and chemical bonds between surfaces moving past each other

1. Downward force of gravity acting on an object (represents the weight of the object)
4. Force due to charged objects moving in a magnetic field
5. Supporting force exerted on an object in contact with a surface (always drawn perpendicular to the surface on which the object is resting
7. Force caused by excess electrical charge
8. Force that does not make contact when applying a force
9. Force on an object by a living person, animal, or other object
10. An upward force exerted on an object and equal to the weight of the fluid displaced by the object
12. Resistane Force that acts upon objects as the travel through air and opposes the motion of an object
13. Caused by attraction of atoms/molecules within a stretched rope or string
16. Force that is caused between the interaction of electrical charges while opposite charges attract
17. Exerted by compressed or stretched spring upon any object that is attached to it. The object restores back after the action
