ELI5: How people are injured by bombs?

I don't quite get how bombs are actually deadly. I understand that people can get thrown up in the air or against walls and be injured but what moves them? Shock waves? How? Is it the actual metal parts of the bomb exploding like shrapnel that can harms? Does dropping a bomb from an aircraft make it more powerful?

To list out the various ways briefly:

1. Force: The detonation itself is very powerful. The force of the energy moving outwards can pick you up and throw you- provided it's a strong enough explosion.

2. Shrapnel: Some bombs are designed to put out more shrapnel- they have metallic bits in them. in fact, some home-made bombs have been packed with nails to embed themselves in people. Otherwise, debris around the area of explosion can act as shrapnel.

3. Heat: It burns. Nuff said.

4. Dropping bombs from planes: They're typically dropped from planes because of volume, and efficiency reasons. It isn't efficient to carry a bomb into a target zone and leave and detonate it.
