Across
- 3. The SI unit of force, defined as the force needed to accelerate a one-kilogram mass at a rate of one meter per second squared (1m/s^2)
- 9. The total, resultant force acting on an object, calculated by adding all individual forces as vectors
- 10. The rate at which velocity changes over time
- 13. The average location of all the mass in a system, acting as a single point where an object's entire mass is concentrated for analytical purposes
- 15. A force that opposes relative motion between surfaces in contact
- 16. A measure of the amount of matter in an object and its inertia, which is its resistance to acceleration
Down
- 1. An interaction that causes a change in an object's motion, shape, or velocity
- 2. A region of space where an object would experience a non-contact force, with the field's strength and direction at each point described by vectors
- 4. The force exerted on an object due to gravity
- 5. The tendency of an object to resist changes in its state of motion
- 6. A visual representation of all the external forces acting on a single object in a physics problem
- 7. The contact force exerted by a surface on an object that is perpendicular to the surface
- 8. A quantity that has both magnitude (size or length) and direction
- 11. A state where an object is not accelerating because the net force and net torque acting on it are both zero
- 12. The single force, velocity, or other vector quantity that has the same effect as two or more other vectors acting on an object
- 14. A scalar quantity that defines the rate at which an object covers distance
