  • True or False: In an electric circuit, current flows from the positive terminal to the negative terminal.
    (True: Conventional current flows from positive to negative, even though electrons flow in the opposite direction.)
  • True or False: The temperature of a substance is a measure of the average kinetic energy of its particles.
    (True: Temperature is directly related to the average kinetic energy of particles in a substance.)
  • rue or False: The speed of light is faster in water than in a vacuum
    (False: The speed of light is slower in water than in a vacuum.)
  • True or False: Absolute zero is the lowest possible temperature, where molecular motion stops completely.
    (True: Absolute zero is 0 Kelvin, where particles have minimal thermal motion.)
  • True or False: Sound travels faster in air than in water.
    (False: Sound travels faster in water than in air.)
  • True or False: Gravity is a force that only affects large objects, like planets and stars.
    (False: Gravity affects all objects with mass, regardless of their size.)
  • True or False: An object in motion will stay in motion unless acted upon by an external force.
    (True: This is Newton's First Law of Motion.)
