Physics Vocab

1. the motion of an object under the sole influence of gravity
4. the speed of an object at a specific moment in time
5. the speed of an object in a specific direction
6. a quantity of change with respect to another quantity, typically time, expressed as a ratio
9. the rate at which an object's velocity changes over time
10. the total distance an object travels divided by the total time it takes to cover that distance
12. the single vector that represents the combined effect of two or more individual vectors acting simultaneously, found through vector addition
13. a scalar quantity that represents the part of a vector's magnitude that points along a specific coordinate axis, such as the x or y axis

2. the interval or duration between the start and end of an event
3. a physical quantity that possesses both magnitude (a numerical value or size) and direction
7. a physical quantity that is completely described by its magnitude (a numerical value with units), and does not have a direction
8. a measurement or concept that depends on the observer's frame of reference, meaning it changes based on their motion
11. a scalar quantity that describes the rate at which an object changes its position, calculated as the total distance traveled divided by the time
