V9 Exam: Forces • Subtopic: Definition of Force Force is an interaction (push or pull) exerted from one object to another. P = F / S When a force is applied to an object, it can cause two types of changes: - Change in shape - Change in motion • Subtopic: Effects of Force Forces can: - Cause an object to expand or contract - Bend or deform an object - Break an object - Set an object in motion - Stop an object in motion - Speed up an object - Slow down an object - Make an object turn • Subtopic: Vector Forces Vector forces are used to represent the magnitude and direction of a force applied to an object. Examples of forces: - Connectest (likely meant "connects" or "connections") - Net force = 12 N - 2 N - 5 N - 4 N - 9 N - 8 N - 6 N • Subtopic: Types of Forces There are two main types of forces: **Action-at-a-distance** Interaction between objects that are not in physical contact. The magnitude of these forces depends on the distance between the objects. **Contact forces** Forces that occur when objects are in physical contact with each other. Examples include: - Magnetism: The force exerted when objects a...
