Physics project

2. A testable prediction or explanation about a phenomenon, based on observations or prior knowledge.
7. Fall: The motion of an object falling under the influence of gravity alone, with no air resistance.
9. Velocity: The velocity of an object at a specific moment in time.
10. Point: A fixed point used to determine the position of an object, typically stationary.
11. The amount of matter in an object, which determines its resistance to acceleration and its gravitational pull.
13. The straight-line distance between an object's starting and ending points, including direction (vector quantity).
15. The speed of an object in a specific direction (vector quantity).

1. The rate at which an object's velocity changes over time (vector quantity).
3. The location of an object at a particular time, often defined relative to a reference point.
4. of Reference: A coordinate system or viewpoint from which an observer measures and describes the position, velocity, and acceleration of objects.
5. The force exerted on an object due to gravity, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).
6. The tendency of an object to resist changes in its state of motion; objects at rest stay at rest, and objects in motion stay in motion.
8. The total path length traveled by an object, regardless of direction (scalar quantity).
12. The rate at which an object moves, calculated as the distance traveled divided by the time it takes (scalar quantity).
14. Velocity: The total displacement of an object divided by the total time taken to travel that displacement.
