Why does a cannonball sink?
A cannonball sinks because it is denser than water. The weight of the cannonball pushes it downwards, overcoming the buoyant force of the water. This causes the cannonball to displace water equal to its weight, resulting in it sinking to the bottom.
When a cannonball is fired is momentum conserved for the cannonball system as a whole?
Yes, momentum is always conserved in a system unless acted upon by an external force. When a cannonball is fired, the momentum of the cannonball system as a whole remains constant because the momentum of the cannonball is equal and opposite to the momentum of the recoil of the cannon.
How does a cannonball work?
A cannonball is fired by a cannon due to the buildup of pressure behind it when ignited. The explosion of gunpowder causes the cannonball to be propelled out of the cannon at high speed. The trajectory and distance the cannonball travels is influenced by factors such as the angle of the cannon and the amount of gunpowder used.
When a cannonball is fired is momentum conserved for the cannon cannonball system?
Yes, momentum is conserved in the cannon-cannonball system. When the cannon fires the cannonball, the cannon moves in the opposite direction to conserve momentum. This is based on the principle of conservation of momentum in a closed system.
Is it possible that the cannonball will miss the ground?
No, assuming gravity is the only force acting on the cannonball, it will eventually hit the ground.
