Physics Vocab

2. Downward acting force created by gravity acting on the mass of an object.
4. Weight A property of objects that corresponds to how heavy an object is.
10. In every interaction there is a pair of forces acting on two interacting objects.
11. Property of matter that resists changes in speed or direction.
13. Body Diagram Sketch that isolates a single object and uses arrows to represent factors.
14. Force Combination of all forces.
16. A force which brings equilibrium state it is considered to be equal and opposite to resultant force.
17. Friction Friction force that occurs between two surfaces that are at rest with respect to each other.

1. Being pulled down by planet's gravity.
3. Push or pull.
5. Second Law Acceleration of an object is proportional to the net force acting on it.
6. Friction Force exerted on an object in motion that opposes another object.
7. State of a system in which all forces are in balance.
8. Force Always opposite to the object's motion.
9. field The region of space surrounding a body in which another body experiences a force of gravitational attraction.
12. Velocity Speed at which air friction and weight become equal and downward acceleration ceases.
14. Force Force perpendicular to a surface. Typically created where objects touch other objects or surfaces such as floors.
15. Force that pulls or stretches a material.
17. Group of related and interacting objects and influences that we choose to investigate.
