For this section use the following forces: gravity, electromagnetic force.

1. compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different.

GRAVITY : 

1. Gravity is a weak force, but has only one sign of charge.
Electromagnetism is much stronger, but comes in two opposing signs of charge.

2.Gravitational charge is equivalent to inertia Electromagnetic charge is unrelated to inertia.

Electromagnetic force :
1. Electromagnetism is much stronger, but comes in two opposing signs of charge.
2. Electromagnetic charge is unrelated to inertia.
