  1. 2. A variable in an experiment that is kept constant to ensure that the test results are reliable and unaffected by other factors.
  2. 5. The motion of an object falling solely under the influence of gravity, without any other forces acting on it.
  3. 6. The force exerted on an object due to gravity, calculated as Weight=Mass×Gravitational Field Strength.
  4. 9. To spread out or scatter energy into the surroundings, typically as heat.
  5. 11. A force that resists the relative motion or tendency to move of two surfaces in contact.
  6. 14. The quantity of matter in an object, measured in kilograms or grams, and is independent of gravity.
  7. 16. Energy that is not usefully transferred and often dissipates into the surroundings, usually as heat or sound.
  8. 17. The process of transferring thermal energy from one body or system to another due to a temperature difference.
  9. 18. The force per unit mass experienced by an object in a gravitational field, commonly approximated as 9.8 N/kg on Earth.
  10. 19. The variable in an experiment that is deliberately changed to observe its effect on the dependent variable.
  11. 20. A summary of the results and findings of an experiment, determining whether the evidence supports the hypothesis.

  1. 1. Relating to motion; kinetic energy refers to the energy an object possesses due to its motion.
  2. 3. The variable being measured or tested in an experiment, which is affected by changes in the independent variable.
  3. 4. A force that opposes the motion of an object moving through air, caused by collisions between the object's surface and air molecules.
  4. 7. Relating to heat; thermal energy is the internal energy of an object due to the movement of its particles.
  5. 8. A force of attraction between two masses, most commonly experienced as the force that pulls objects towards the Earth.
  6. 10. Information or data collected during an experiment or investigation to support or refute a hypothesis or conclusion.
  7. 12. A statement about what is expected to happen in an experiment, based on prior knowledge or hypothesis.
  8. 13. In physics, work is the energy transferred to or from an object via the application of force along a displacement.
  9. 15. Energy transferred to a desired form or location to perform a specific task.
