Statements for item 1
I. Inertia is the property of matter that prevents it from moving.
II. Inertia is the property of matter that keeps it moving with the same speed.
III. Based on the Law of Interaction, the reaction force is stronger than the action force. An example is the propeller’s action that creates a reaction force that moves the vessel.
IV. The buoyant force supporting the vessel must be higher than the weight of the vessel to prevent it from sinking.
1. What can be concluded from the statements above?
From the statements above, we can conclude that:
- Statement I is true, as inertia is the property of matter that prevents it from moving.
- Statement II is false, as inertia is the property of matter that keeps it moving at the same speed, not with the same speed.
- Statement III is true, as based on the Law of Interaction, the reaction force is equal in strength and opposite in direction to the action force.
- Statement IV is true, as the buoyant force must be greater than the weight of the vessel in order to prevent it from sinking.
