  1. 3. Forces that are unequal in size, causing an object to start moving, speed up, slow down, or change direction.
  2. 5. A measure of the gravitational force acting on an object's mass; it is measured in Newtons (N).
  3. 7. Having a smooth shape designed to minimise the effects of air or water resistance.
  4. 10. A push or a pull exerted on an object due to interaction with another object.
  5. 11. Resistance A type of friction caused by air pushing against moving objects (also known as drag).
  6. 12. / Buoyancy The upward push of a liquid or gas on an object floating in it.
Down
  1. 1. A measure of the amount of matter in an object; it stays the same regardless of location.
  2. 2. A contact force that acts when two surfaces rub against each other, working to slow down or oppose motion.
  3. 4. Resistance A type of friction caused by water pushing against moving objects.
  4. 6. Forces that are equal in size and opposite in direction; they cause no change in an object's motion.
  5. 8. A non-contact force that pulls objects toward each other; it is most noticeable with large objects like the Earth, which pulls everything towards its centre.
  6. 9. A non-contact force that can attract (pull) or repel (push) certain materials like iron, nickel, and cobalt.
