Across
- 2. is when the forces acting on an object are not equal, resulting in a net force that is not zero.
- 6. is the rate at which an object's velocity changes over time, measured in meters per second squared (m/s²).
- 7. is the force that opposes the relative motion between two surfaces in contact, acting parallel to the surfaces and in the direction opposite to the motion.
- 8. is the pulling or stretching force transmitted along a flexible connector, like a rope, string, or cable, when force is applied to both ends.
- 10. is the force exerted on an object by another object, often resulting in motion or deformation.
- 12. is the standard international (SI) unit of force, defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared (1 N = 1 kg⋅m/s²).
- 13. is a push or a pull that can cause an object to change its velocity (speed or direction), change its shape, or both.
- 14. is the universal force of attraction between any two objects with mass or energy, holding celestial bodies in orbit, keeping our atmosphere, and causing objects to fall to the ground on Earth.
- 15. is defined as the quantity of matter in an object and is also a measure of its inertia, or resistance to changes in motion.
Down
- 1. is the vector sum of all forces acting on an object, also known as the resultant force.
- 3. occurs when multiple forces acting on an object are equal in magnitude and opposite direction, resulting in a net force of zero.
- 4. the large-scale structural features and processes involving Earth's outer shell (the lithosphere), which is broken into rigid plates that move and interact.
- 5. is the natural tendency of any physical object to resist changes in its state of rest or uniform motion.
- 9. is defined as a vector quantity that measures how fast an object is moving and in what direction.
- 11. is the strength or force an object or process gains through motion or a series of events, making it difficult to stop once it has started.
