Question 1:
According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by:
Explanation: The correct answer is A) An external force. According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by an external force.
Question 2:
Which of Newton's laws of motion explains the relationship between an object's mass, acceleration, and the applied force?
Explanation: The correct answer is B) Newton's second law. Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Question 3:
According to Newton's third law of motion, for every action, there is:
Explanation: The correct answer is A) An equal and opposite reaction. Newton's third law of motion states that for every action, there is an equal and opposite reaction.
Question 4:
Which of the following best describes the concept of inertia?
Explanation: The correct answer is A) The resistance of an object to change its state of motion. Inertia is the property of an object to resist changes in its state of motion, whether at rest or in motion.
Question 5:
Which of Newton's laws of motion is also known as the law of action-reaction?
Explanation: The correct answer is C) Newton's third law. Newton's third law of motion, also known as the law of action-reaction, states that for every action, there is an equal and opposite reaction.
