Across
- 5. a contact force exerted by a surface on an object, acting perpendicular to the surface
- 6. The rate of change of velocity. It is a vector that indicates a change in speed, direction, or both.
- 8. a simplified graphical representation of all the external forces acting on a single object
- 10. The magnitude of velocity. It is a scalar quantity, meaning it only has magnitude and no direction.
- 14. the property of an object that resists changes to its state of motion
- 16. weight is the force of gravity on an object
Down
- 1. the unique point in a system where the weighted average position of all its mass is located
- 2. A push or pull on an object.
- 3. A force that opposes motion or the tendency of motion between surfaces in contact
- 4. The vector sum of all forces acting on an object.
- 7. a non-contact force that acts on an object through a region of space called a field
- 9. The state where the resultant force on an object is zero. The object is either at rest or moving with a constant velocity.
- 11. the total force acting on an object, calculated as the vector sum of all individual forces
- 12. A quantity with both magnitude and direction, such as displacement, velocity, acceleration, and force.
- 13. a measure of the amount of matter in an object, and it also quantifies an object's inertia, or resistance to a change in motion
- 15. A newton is the SI unit of force, defined as the force required to accelerate a one-kilogram mass at a rate of one meter per second squared
