what makes my car jerk when i put it in gear
Assuming your car has an automatic transmission, it sounds like you may be low on transmission fluid. Automatic transmissions use transmission fluid that is pressurized to shift gears. When the transmission is low on fluid, this can cause delays in shifting or a bit of a jerking reaction due to the delay in building up the required hydraulic pressure to shift into gear. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
