  1. 2. The rate at which an object's velocity changes over time.
  2. 7. The resistive force that opposes the motion of objects in contact.
  3. 10. force The perpendicular force exerted by a surface on an object resting on it.
  4. 11. A quantity that has both magnitude and direction, like velocity or force.
  5. 12. The distance traveled per unit of time, a scalar quantity.
  6. 13. The force exerted on an object due to gravity, calculated as mass times gravitational acceleration.
  7. 14. A state in which all forces on an object are balanced, so there is no net force.

  1. 1. of mass The point where the mass of an object is evenly distributed and balanced.
  2. 3. force The total force acting on an object, calculated by summing all individual forces.
  3. 4. field field A region in space where an object experiences a force, such as a gravitational or electric field.
  4. 5. The tendency of an object to resist changes in its state of motion.
  5. 6. The SI unit of force, where one newton equals the force needed to accelerate a 1 kg object by 1 m/s².
  6. 7. diagram A simplified drawing showing all the forces acting on an object.
  7. 8. An interaction that changes the motion of an object, measured in newtons (N).
  8. 9. The single force that has the same effect as all the forces acting on an object combined.
  9. 15. The amount of matter in an object, usually measured in kilograms.
