Gravity and Buoyancy
gravity and upthrust.
You need to draw this \______/ floating on water to show a floating boat.
up thrust and gravity
Because boat means something that is floating in the water.
The forces are: Thrust: from a propeller, impeller, sail or paddleDrag: from the water and also the air acting on the hull, superstructure, sails, mast or riggingRoll: wind and waves that move the boat from side to sidePitch: wind and waves which move the boat fore and aftYaw: can be caused by thrust, drag, wind or waves turning the boat in the horizontal planeBuoyancy: keeps the boat floating due to the displacement of the hullPlaning forces: lift the boat vertically due to aerodynamic and hydrodynamic forces acting on the hull
Boat and barge or floating logs for logging
1) FORCE EXERTED BY THE BODY TOWARDS EARTH {WEIGHT} 2) FORCE EXERTED BY WATER ON THE BODY [DUE TO DISPLACED WATER] NOTE:- HERE THERE WILL BE NO VISCOUS FORCE
The water density is higher than the boat's therefore it floats on the water.
climb onto the bottom of the overturned boat
lower
It's called the buoyancy force.
As per Archimedes principle for floating the weight of the displaced water has to be equal to the weight of the boat. Hence for more water to get displaced the boat has to sink more.
