Question 1: Define inertia in your own words.

Answer: Inertia is the tendency of an object to resist changes in its state of motion or rest.

Question 2: Explain how inertia relates to Newton's First Law of Motion.

Answer: Inertia is the property that causes an object to resist changes to its motion, which is the basis of Newton's First Law stating that an object remains at rest or in uniform motion unless acted upon by an external force.

Question 3: Provide a real-world example that illustrates inertia.

Answer: A passenger lurches forward when a car suddenly stops because their body resists the change in motion due to inertia.

Question 4: Identify the variable that affects the amount of inertia an object has.

Answer: The mass of the object.

Question 5: A 10 kg object and a 2 kg object are pushed with the same force. Which object will accelerate more? Explain why.

Answer: The 2 kg object will accelerate more because acceleration is inversely proportional to mass according to Newton's Second Law (F = ma).

Question 6: Calculate the force needed to accelerate a 5 kg object at 3 m/s^2.

Answer: Force = mass × acceleration = 5 kg × 3 m/s^2 = 15 N

Question 7: If an object with a mass of 20 kg has an inertia force of 60 N applied to it, what is the acceleration produced?

Answer: Acceleration = Force / Mass = 60 N / 20 kg = 3 m/s^2

Question 8: Multiple Choice: Which of the following best describes inertia?

Answer: B) The tendency of objects to resist changes in their motion

Question 9: Fill in the blank: The greater the mass of an object, the ______ its inertia.

Answer: greater

Question 10: Describe an experiment you could perform to demonstrate inertia using everyday objects.

Answer: One simple experiment is to place a coin on top of a playing card and quickly pull the card horizontally. The coin will stay at rest due to inertia, demonstrating resistance to change in motion.
