Explanation:

Step1: Analyze the rocket image

When a rocket is launching, the upward thrust force is greater than the downward gravitational force. So the forces are unbalanced.

Step2: Analyze the log (assuming it's in equilibrium) image

If the log (or whatever the object is) is not accelerating (assuming a state like just resting, no net force), the upward and downward forces are equal. So the forces are balanced.

Step3: Analyze the sail - boat image (horizontal forces)

If the boat is moving at a constant speed horizontally (assuming no acceleration horizontally), the left and right forces (like wind and water resistance) are equal. So the horizontal forces are balanced.

Step4: Analyze the sail - boat image (vertical forces)

If the boat is not moving up or down (in vertical equilibrium), the upward (buoyancy) and downward (gravity) forces are equal. So the vertical forces are balanced.

Answer:

unbalanced, balanced, balanced, balanced
