Question 1:
Which of the following is an example of Newton's first law of motion (law of inertia) in everyday life?
Explanation: The correct answer is B) A soccer ball rolling to a stop on grass. Newton's first law of motion (law of inertia) states that an object at rest will remain at rest, and an object in motion will continue moving with a constant velocity, unless acted upon by an external force. In this example, the soccer ball rolling to a stop on grass demonstrates the law of inertia as it naturally slows down and eventually stops due to friction and air resistance.
Question 2:
Which of Newton's laws of motion explains the recoil experienced when firing a gun?
Explanation: The correct answer is C) Newton's third law of motion. Newton's third law of motion states that for every action, there is an equal and opposite reaction. When a gun is fired, the bullet is propelled forward due to the action force, and at the same time, the gun experiences a backward recoil force as the reaction force. This is an example of Newton's third law of motion in action.
Question 3:
Which of the following best describes the application of Newton's second law of motion in everyday life?
Explanation: The correct answer is A) Throwing a ball with more force to make it travel farther. 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. When throwing a ball, applying more force allows for a greater acceleration, resulting in the ball traveling farther. This showcases the application of Newton's second law of motion in everyday life.
Question 4:
Which of the following is an example of Newton's third law of motion in everyday life?
Explanation: The correct answer is B) Bouncing a ball off a wall. When a ball bounces off a wall, the action force is the ball striking the wall, and the reaction force is the wall exerting an equal and opposite force on the ball. This scenario exemplifies Newton's third law of motion, where every action has an equal and opposite reaction.
