Both qualifying sessions will now happen on the Saturday before a race.
As last season, each driver will attempt one flying lap in the first session, with the fastest in the first session going out last in the second.
Being the last driver in a session is an advantage because the track will be warmer making it easier for the car's tyres to grip the road.
Each driver is now allowed only one engine to last them each race weekend.
If the drivers have engine problems the new rules will punish them.
If their engine needs changing before the qualifying sessions on Saturday they will be moved 10 places from where their qualifying time puts them.
If it needs changing after the start of qualifying then the driver will have to start the race from the back of the grid.
The rules have been changed to try and make Formula One less expensive as some teams used to use different engines for qualifying and the race.
Last season drivers were able to press a button when the lights went off and the car started moving.
This year launch control is banned, so drivers will have to work out their own starts using the clutch and the accelerator.
In recent seasons Formula One cars have been fully automatic, so the drivers didn't have to worry about what gear they were in.
This season they will have to choose their own gears, although these are often worked by pressing a button on a steering wheel rather than a gear stick.
Aerodynamics is the way the cars' bodies are designed to work with the air around them to keep them on the road.
When cars are moving air pushes against them, and the aerodynamics of the car are designed so that air is pushing them down onto the track - called downforce.
The harder the air pushes them towards the track the easier they are to drive more quickly.
New rules this year have forced teams to reduce the amount of downforce their cars use, so that the drivers can't go as quickly, hopefully making the races a little bit safer.
