What factors determine inertia in moving a canoe?

Answer 1

Factors that could determine inertia versus movement / acceleration of a canoe might include:

• the weight of the canoe, empty
• whether the canoe is turned upside down on land
• whether the canoe is turned upside down on/in water
• whether the empty canoe is sitting right side up in water but tied or secured to an immovable object
• whether the empty canoe is sitting right side up in water but tied or secured to a movable object, such as another untied /unsecured canoe
  
• whether the canoe has cargo in it and the collective weight
  
• whether the canoe has passengers in it and their collective weights (especially if one or two passengers were very obese)
• whether passengers sat on the floor or bottom of the canoe, versus on the seats (canoe will sit lower in the water, causing more resistance against forward movement)
• whether the empty or weighted canoe is sitting in very still waters
• whether the empty or weighted canoe is sitting in fast moving waters
• whether the empty or weighted canoe is aided to move by a brisk wind
• whether and how many humans paddle the canoe, along with factors of how fast the water is moving and aid of winds
• whether the canoe is moving with the current or against it
• whether the canoe has developed a hole or is taking on water
• whether it is being vigorously rocked side to side while humans are trying to make the canoe move forward or backward
• whether the canoe sits in a whirlpool
• whether the canoe sits in a waterway with a steep downward slope
• whether the canoe was in the direct path of a mudslide hitting a creek, stream, river, or other water source
  
• whether the canoe was paddled close enough to the current right before a rapid or waterfall
• whether the canoe entered a manmade lock on a waterway (controlled movement, inertia)
• whether the canoe suddenly struck a large rock or boulder
• whether the canoe was old and then converted into a flower canoe or some art sculpture so it is weighted or bolted in place
