  1. 3. friction is a force that opposes the relative motion between two surfaces in contact
  2. 6. A free-body diagram (FBD) is a graphical illustration used in physics and engineering to represent all the external forces and moments acting on an object, which has been isolated from its surroundings
  3. 9. Normal force is the support force exerted by a surface that acts perpendicular to that surface against an object.
  4. 12. In physics, a resultant is the single force or vector that represents the combined effect of two or more other forces or vectors.
  5. 15. A force field is a concept in physics representing a region where a force can be detected
  6. 16. A net force is the overall force acting on an object, calculated as the vector sum of all individual forces.

  1. 1. The center of mass is the unique point in a system where the weighted relative position of all its distributed mass sums to zero.
  2. 2. In physics, equilibrium is the state of a system where all forces and torques are balanced, resulting in no net acceleration
  3. 4. a vector is a quantity that has both magnitude (size) and direction
  4. 5. a force is a push or pull on an object that causes a change in its motion, speed, or direction
  5. 7. n physics, acceleration is the rate at which an object's velocity changes over time. T
  6. 8. Inertia is the resistance of an object to any change in its state of motion, meaning an object at rest will stay at rest and an object in motion will stay in motion at a constant velocity unless an external force acts on it
  7. 10. In physics, mass is a fundamental property that measures the amount of matter in an object and its resistance to acceleration, known as inertia.
  8. 11. In physics, weight is the force of gravity on an object, calculated as the product of its mass and the acceleration due to gravity (\(W=mg\)
  9. 13. speed is the rate at which an object changes its position, calculated as the distance traveled divided by the time taken
  10. 14. a newton is the standard unit of force, defined as the force required to accelerate a one-kilogram mass at a rate of one meter per second squared
