  1. 2. The product of an object's mass and its velocity. p = mv
  2. 3. A type of collision where both total momentum AND total kinetic energy are conserved.
  3. 5. The universal attractive force acting between all matter in the universe. Formula: F = G(m₁m₂)/r².
  4. 7. The energy that an object possesses due to its motion. K = 1/2 mv².
  5. 8. The support force exerted upon an object that is in contact with another stable object.
  6. 9. The vector difference between an object's starting and ending positions. In kinematics, if an object experiences constant acceleration.
  7. 11. A state in which the vector sum of all forces acting on an object is exactly zero. In this state, an object will have zero acceleration, meaning it is either at rest or moving at a constant velocity.
  8. 13. The pulling force transmitted axially through a flexible, continuous medium.
  9. 14. A type of collision where total momentum is conserved, but kinetic energy is NOT.
  10. 15. A principle of physics stating that the total momentum of a closed, isolated system remains absolutely constant over time before and after an event.
  11. 18. The change in an object's momentum when a net force is applied over a specific time interval. J = FΔt or J = Δp.
  12. 19. A non-conservative resistive force that opposes the relative motion or tendency of such motion of two surfaces in contact. Formula: Ff = μN.

  1. 1. The vector rate of change of position. If an object is accelerating constantly over a period of time.
  2. 4. A specific, short-duration event where two or more bodies interact and exert relatively strong internal forces on each other, transferring momentum.
  3. 6. The rate at which an object changes its velocity. a = F_net / m.
  4. 10. The specific type of potential energy stored when an elastic object is stretched or compressed from its equilibrium position. U = 1/2(kx^2)
  5. 12. The gravitational force exerted on a mass by a massive body. Fg = mg.
  6. 16. This is the property of matter that resists any change to its state of motion or rest.
  7. 17. The standard SI derived unit of force. 1 N = 1 kg·m/s².
