Explanations: answer key for all 10 questions

Q1: What is another name for Newton's first law?
Answer: The law of inertia
Objects keep their state of motion unless a force acts on them.
Q2: Why do seat belts protect passengers in a sudden stop?
Answer: Inertia keeps the body moving forward
The belt supplies the force needed to slow the body safely.
Q3: What does Newton's second law state?
Answer: Force equals mass times acceleration
Pushing a heavier object with the same force gives less acceleration.
Q4: What is the SI unit of force?
Answer: Newton
One newton accelerates one kilogram by one meter per second squared.
Q5: How does a rocket move in space?
Answer: By pushing gas backward, which pushes it forward
This is Newton's third law in action.
Q6: Which law explains why a swimmer pushes water backward to move forward?
Answer: Third law
Action and reaction forces act on different objects.
Q7: Why does a sliding book eventually stop?
Answer: Friction acts against its motion
Without friction, it would keep sliding.
Q8: In which book did Newton publish his three laws?
Answer: Principia
It was published in 1687.
Q9: Which is harder to stop, a truck or a bicycle moving at the same speed?
Answer: A truck
More mass means more momentum.
Q10: In deep space with no forces, what does a moving spacecraft do?
Answer: Keeps moving in a straight line
This is why probes coast for years.

Newton'S Laws Trivia Quiz – Three Laws That Explain Motion

Isaac Newton's three laws of motion, published in 1687, describe how forces change the way objects move. The first law says objects resist changes in motion, a property called inertia. The second links force, mass and acceleration in the famous equation F = ma. The third says forces always come in equal and opposite pairs.

These laws explain countless everyday events. Seat belts and airbags protect passengers because their bodies keep moving when a car stops suddenly. Athletes push against the ground to run, swimmers push water backward and rockets push hot gas out of their engines to move forward.

Newton's laws work extremely well for everyday speeds and sizes, and engineers use them to design bridges, cars, aircraft and spacecraft. Only at very high speeds or tiny scales do Einstein's relativity and quantum physics take over.
