Across
- 4. a graphical representation of an object with all the external forces acting on it shown as arrows
- 6. the single force or vector that is the equivalent to the combined effect of two or more other vectors
- 9. the perpendicular contact force exerted by a surface on an object, acting to support it against another force like gravity
- 11. the rate at which an object's velocity changes over time
- 13. the overall force acting on an object, calculated by taking the vector sum of all individual forces
- 15. a region of space where a non-contact force (like gravity, electricity, or magnetism) acts on an object
- 16. a measure of the amount of matter in an object and its resistance to acceleration
Down
- 1. the force of gravity acting on an object's mass
- 2. a quantity with both magnitude (size) and direction
- 3. a force that opposes the relative motion or attempted motion between two surfaces in contact
- 5. the resistance of an object to any change in its state of motion
- 7. the rate at which an object covers distance, calculated by dividing distance by time
- 8. a push or pull that causes an object with mass to change its velocity (accelerate), direction, or shape, measured in Newtons (N)
- 10. SI unit of force, defined as the amount of force needed to accelerate a one-kilogram mass at a rate of one meter per second squared
- 12. the average position of all the mass in an object or system, where an object can be considered to move as if all its mass were concentrated at that single point
- 14. the state of a system where all forces are balanced, resulting in zero net force and therefore zero acceleration
