Question

question 4.
(book experiment) experiment each of newton’s laws of motion acting simultaneously in this experiment?
one - word answer in each box.
the ice cube exerts a 2 n force on the wall and the wall exerts a 2 n force back on the ice cube.
the ice cube travels at a constant velocity along the countertop until it hits the wall.
the amount of force that a student uses on the ice cube will determine the acceleration of the ice cube.
newton’s 1st law
newton’s 2nd law
newton’s 3rd law

Explanation:

Step1: Analyze each statement and Newton's Laws

• Statement 1: The ice cube exerts a 2 N force on the wall and the wall exerts a 2 N force back on the ice cube.

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This describes action - reaction pairs, so this statement relates to Newton's 3rd Law.

• Statement 2: The ice cube travels at a constant velocity along the countertop until it hits the wall.

Newton's 1st Law (Law of Inertia) states that an object in motion will stay in motion with a constant velocity (and an object at rest will stay at rest) unless acted upon by a net external force. Since the ice cube moves at constant velocity (no net force, assuming negligible friction), this relates to Newton's 1st Law.

• Statement 3: The amount of force that the student uses on the ice cube will determine the acceleration of the ice cube.

Newton's 2nd Law is given by \(F = ma\) (force equals mass times acceleration), which shows the relationship between force and acceleration. So this statement relates to Newton's 2nd Law.

Step2: Match each statement to the correct law

• For the statement about action - reaction (ice cube and wall forces): Match to Newton's 3rd Law.
• For the statement about constant velocity (inertia): Match to Newton's 1st Law.
• For the statement about force and acceleration: Match to Newton's 2nd Law.

Answer:

• "The ice cube exerts a 2 N force on the wall and the wall exerts a 2 N force back on the ice cube." → Newton's 3rd Law
• "The ice cube travels at a constant velocity along the countertop until it hits the wall." → Newton's 1st Law
• "The amount of force that the student uses on the ice cube will determine the acceleration of the ice cube." → Newton's 2nd Law
