True or False: If a cannon fires a cannonball in an easterly direction, the tendency of the cannon to move to the west is a result of the principle of conservation of energy.
hardly. What do you think?
false, its called the coriolis effect
False.
The tendency of the cannon to move to the west when firing a cannonball in an easterly direction is not a result of the principle of conservation of energy. Instead, it is due to the principle of conservation of momentum. When the cannon fires the cannonball, the cannon exerts a backward force on the cannonball, known as the reaction force. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, the cannon experiences a forward force equal in magnitude but opposite in direction to the force exerted on the cannonball. This results in the cannon moving to the west. Conservation of energy, on the other hand, refers to the total energy in a system remaining constant.
False. The tendency of the cannon to move to the west when firing a cannonball in an easterly direction is not a result of the principle of conservation of energy.
When a cannon fires a cannonball, both the cannon and the cannonball experience a reaction force. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, when the cannonball is expelled in the easterly direction, the cannon experiences a force in the opposite direction, which causes it to move to the west.
The principle of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. In this case, the conservation of energy is not directly relevant to the motion of the cannon. The conservation of momentum, however, plays a role. The momentum of the cannonball and the cannon are equal and opposite, meaning their combined momentum is conserved.
