Unit 3 force

4. a force that is applied by objects in contact with each other.
5. is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
6. a net force that results when the forces acting on an object are not equal and opposite, causing the object to accelerate or change its state of motion.
12. forces that occur together when two objects interact.
13. forces that are equal in magnitude and opposite in direction, resulting in no net force and no change in an object's motion

1. the resistance that one surface or object encounters when moving over another.
2. strength or energy as an attribute of physical action or movement.
3. the vector sum of all individual forces acting on an object
7. for every action there is an equal and opposite reaction
8. is the force that attracts a body towards the center of the earth or a physical body with mass.
9. a force that acts on an object without requiring physical contact, meaning the objects don't need to touch each other to exert an influence.
10. the force that surfaces exert to prevent solid objects from passing through each other.
11. the great size or extent of something.
