Across
- 3. the total force acting on an object, which is the combination of all individual forces
- 4. a push or a pull that can change an object's motion by causing it to accelerate or deform
- 9. the force that opposes the motion of two surfaces as they slide against each other
- 12. the amount of space between two points or the total length of a path traveled
- 14. a force that causes an object to change its motion, because the forces acting on it are not equal in magnitude
- 16. a measure of the force of gravity on an object, or its heaviness.
- 18. the force that opposes the motion of an object moving through a fluid (like a liquid or gas) or the friction between layers of the fluid itself
- 19. the force that opposes an object's motion through the air, also known as drag
- 20. "mass in motion" of a moving object, determined by how fast it is going and how heavy it is
Down
- 1. force required to accelerate a one-kilogram mass at a rate of one meter per second squared
- 2. the rate at which an object's velocity (speed and direction) changes over time
- 5. the rate of change of position, including direction
- 6. the tendency of an object to resist changes in its state of motion
- 7. the amount of matter in an object, and it is also a measure of an object's resistance to acceleration
- 8. the force that opposes the relative motion between two surfaces in contact, slowing them down
- 10. equal forces acting in opposite directions, which cancel each other out, resulting in zero net force
- 11. how fast an object is moving, calculated by dividing the distance traveled by the time it took
- 13. the force that opposes the motion of a rolling object, like a wheel or ball, on a surface
- 15. quantity that has magnitude (size) only, but no direction
- 17. the force of attraction that pulls objects with mass toward each other
