When lightning strikes a surface, it strikes it will all the energy that it contains and this causes it to heat up to very high temperatures, which in smaller objects can cause them to burn up. In a surface which has large area, this energy gets dissipated over the entire surface and the amount of heat per unit area gets considerably reduced. A lightning rod works on transferring this large amount of energy to the ground so that the heat energy can be dissipated harmlessly.
Lightning itself is neither good nor bad; it is a natural atmospheric discharge of electricity. However, it can be dangerous if it strikes a person or a flammable object, causing injury or starting fires. It is important to take precautions during thunderstorms to avoid potential harm from lightning strikes.
Lightning commonly strikes the same place many times. Lightning is static electricity, generated in the collisions between the clouds. The lightning wants to ground itself by striking something with a good electrical pathway to the earth. That could be a tall tree, or a steeple, or a house chimney, or any tall object that will intercept the lightning strike and bring it to ground. Lightning will strike twice if the same place it struck before is still a good, high, electrical path to the ground, and if no better places have been built.
The atoms in metals are not connected to a peticular atom so they are allowed to travel without being stopped throughout the material. This creates a conductivity to electricity. Lightning tends to head twoards object with the most conductivity thus being metal. This is also why being in a car is the safest place to be in during a lightning storm. the lightning will travel through the metal frame around the car and if im not mistaken leave through the ground (the tires) in the end not harming you.
A metallic object, like an umbrella with a metallic head, can act as a conductor for electricity and increase your risk of being struck by lightning during a storm. It is safer to seek shelter in a sturdy building or a car with a hard metal roof to protect yourself from lightning.

A lightning rod is designed to protrude above the highest point of a building. A lightning strike will (hopefully) strike the rod, rather than damage the building itself. The charge will travel safely to earth along a metal cable fixed between the rod and the ground.
Lightning rods are designed to provide a path for lightning to strike the earth safely by conducting the electrical current from the cloud to the ground. By offering a low-resistance path, they help protect buildings and structures from damage caused by lightning strikes.

Nope - lightning can strike the same place multiple times if the object presents enough ionic attraction to ground the charge.
Two objects like this will tend to attract each other. If the difference in charges is large enough then a discharge (similar lightning) might occur.
In addition to providing a conducting path to ground in case a lightning strike occurs, lightning rods also reduce the number of large lightning strikes by reducing the static charge build-up in the atmosphere around the building. The pointed end of the rod creates an attraction point for the excess charge and siphons it to ground, reducing the charge difference between the cloud and the building.If you get a chance to deal with a small Tesla coil or small static generator, set up a situation in which sparking is occurring between a broad object (like a sphere) and the coil/generator . Then introduce a grounded thin rod (or some other grounded pointy object). the sparking will stop and there may be some micro-lightning (and soft crackling sound) around the point.Basically, the pointy grounded rod creates smaller, lower energy lightning to prevent the huge damaging strikes.
The charge repels so if it's a conductor the charge moves as far away as possible (the side of the object). It will also attract other objects with an opposite charge, or repel ones with like charge.
you would want to stay away from trees and anything tall. lightning strikes the tallest object in a field
A jolt of lightning is a sudden, intense burst of electrical energy generated by a thunderstorm. It is typically visible as a bright flash in the sky and can be accompanied by a loud thunderclap. Lightning strikes can be dangerous and cause damage to structures and harm to living beings.
Lightning is more dangerous than thunder because it can cause injury or death if it strikes a person or object. Thunder, on the other hand, is merely the sound produced by lightning as it heats the air and creates a shockwave.
