  1. 3. Concept in physics that makes clear how objects change one another’s shape and/or motion.
  2. 7. How much N/kg is 500 kg?
  3. 9. A force that arises when the muscles in a body contract.
  4. 10. A force that acts perpendicularly to the object’s surface. An example is the force a tabletop exerts on a fruit bowl.
  5. 12. Way of representing the size, direction and point of application of a force as an arrow.
  6. 13. The force with which the Earth attracts you and all the objects around youthful A force that arises when the muscles in a body contract.
  7. 14. What is the spring constant in newtons per metre, if the force that pull the string is 200 newton and the extension is 50 cm?
  8. 15. The sum of the forces acting on an object. The forces have to be added as vectors, not numbers.

  1. 1. The increase in the length of a spring when a force is exerted on it.
  2. 2. The force that an object exerts on whatever it is resting on as a result of the force of gravity acting on the object.
  3. 4. The length of a spring that has not been extended.
  4. 5. what is the resultant force if the wind is pushing a car 100 N and the cars force is 400?
  5. 6. A force that arises in a rope if it is pulled at both ends.
  6. 8. A state in which an object has no weight because it is not resting on anything or suspended from anything.
  7. 11. A force that arises when you extend or compress a springy material.
