Mass and Acceleration (F=ma)
Bouyancy... its what makes things float in water.
Gravity.
The upthrust exerted by surrounding air on the balloon.
G force is the gravity force. When you go up on a swing and at the highest point you feel weightless, that is negative g force. When you are in one of those rides that makes you feel super heavy (or when you're at the bottom of a big hill on a roller coaster) that is positive g force. Both negative and positive g force can kill you. Positive g force makes blood have a hard time getting to the brain and negitive g force makes it too easy to get blood to your brain. Before you die, you throw up, then pass out. Don't worry about going on roller coasters though. In the USA rides are only alowed to have 3.5 g force each way (i think, can someone check my numbers?) and you throw up at 5 g force each way and at 10+ g force each way you pass out.
Friction! When you rub objects or substances together the microscopic rough particle begins to heat up and eventually it gets hot enough to start the combustion process.
