Types of Force

5. Upward force on an object, often generated by differences in air pressure
6. Force that is exerted on an object by another object or by a person
7. Force that a surface exerts on an object perpendicular to the surface
9. Force that attracts objects toward each other, especially toward the center of the Earth
11. Force that pulls on an object, often transmitted through a rope or cable
12. unit of force, equal to the force needed to accelerate 1 kilogram by 1 meter per second squared
15. Force that causes an object to follow a curved path, directed toward the center of the curve
17. Force exerted by a coiled elastic object when it is compressed or stretched
18. Force that holds the protons and neutrons together in the nucleus of an atom
19. Upward force exerted by a fluid on an object immersed in it

1. Apparent force that draws an object away from the center of a curved path
2. Force that opposes the motion of an object through the air
3. Force that pushes on an object, often causing it to squeeze or shorten
4. Force of attraction or repulsion between electrically charged objects
8. Force of attraction or repulsion between magnets or magnetic objects
10. Forces that do not cancel each other out, resulting in a change in motion
13. Force that propels an object forward, often generated by an engine or propeller
14. Forces that cancel each other out, resulting in no change in motion
16. Force that resists motion between two surfaces in contact
20. Total force acting on an object, found by combining all the forces acting on it
