Answer 1

ForceA. Force is the **cause** of acceleration, or change in an object's velocity.1. The combination of all the forces acting on an object is called the **net force**.2. **Balanced forces** completely cancel each other and equal zero.3. **Unbalanced forces** do not cancel each other out and do not equal zero.III. Friction and Air ResistanceA. **Friction** is the force between two objects in contact that opposes the motion of either object.1. Vary depending on the **surfaces in contact**. (e.g., roughness, materials)2. **Air resistance** is a form of friction. a. Depends on **speed** and **surface area**, as well as the **shape** in which it moves.IV. GravityA. Gravity is the **force of attraction** between two objects due to their **masses**.1. **Mass** and **distance** affect gravitational force.
