Directions: Write TRUE if the statement correctly describes friction and gravity and
FALSE if it is incorrect. Write your answer on the space before the number.
______1. When a car goes upward on a hill, it moves against gravity.
______2. Friction is a force that pulls all objects down to Earth’s center.
______3. Gravitational pull is less on the moon than on Earth.
______4. If there is no air resistance, objects dropped from the same height
will hit the ground at the same time.
______5. Isaac Newton observed that an apple falls from a tree because of
gravity.
______6. The moon’s gravitational pull causes seawater to rise that results in
a low tide.
______7. A ball that is thrown upward will eventually fall to the ground
because of frictional forces.
______8. Any object falling without air resistance is in the state of free fall.
______9. The sun’s gravitational pull keeps the planets in the solar system in
their orbits.
______10. Earth’s gravity acts more strongly on an object located on top of
Mt. Everest than an object located at sea level.
