Here are the step-by-step solutions for each question:
Question 6:
Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means forces always come in pairs.
*
Correct Option: b. An equal and opposite reaction.
Question 7:
The example describes an object (a book) staying at rest until a force acts on it. This is the definition of inertia, which is explained by Newton's first law of motion (often called the Law of Inertia).
*
Correct Option: b. Newton’s first law of motion
Question 8:
Newton's second law of motion gives us the formula for force: $Force = Mass \times Acceleration$ ($F=ma$).
*
Correct Option: c. Its mass times acceleration
Question 9:
When objects fall, gravity pulls them down with a force equal to their weight. Weight depends on mass ($Weight = Mass \times Gravity$). Since all items are falling at roughly the same speed due to gravity, the item with the most mass will hit the ground with the greatest force (impact). A book is much heavier than a pencil, paper clip, or crayon.
*
Correct Option: a. The book
Question 10:
Gravity is the invisible force that pulls objects toward the center of the Earth. When you drop something, gravity is what pulls it down to the ground.
*
Correct Option: b. Gravity
