Across
- 3. force the total vector sum of all forces acting on an object
- 4. a push or pull that can change an object's motion, shape, or direction
- 7. of mass the unique point in a system where all its mass is considered to be concentrated for the purposes of calculating motion
- 8. body diagram a graphical sketch that represents all the external forces acting on a single object.
- 10. a measure of the amount of matter in an object and its resistance to acceleration (inertia)
- 12. the rate of change of an object's velocity with respect to time
- 13. a force that opposes motion between two surfaces in contact.
- 15. the force of gravity on an object, calculated as mass multiplied by the acceleration due to gravity
- 16. force a contact force exerted by a surface that is always perpendicular to that surface
Down
- 1. the tendency of an object to resist changes in its state of motion, whether it is at rest or in motion
- 2. field a region in space where an object experiences a non-contact force, defined by the strength and direction of the force at every point
- 5. a state of balance where an object or system experiences no change in its state of motion or internal energy
- 6. a quantity that has both magnitude (size) and direction
- 9. the single vector that represents the combined effect of two or more vectors
- 11. the rate at which an object covers distance, defined as the total distance traveled divided by the total time taken
- 14. the force needed to accelerate a one-kilogram mass at one meter per second squared
