Usually the balloon in the van would try to go straight up, what is responsible for it going towards the back of the van? The tension in the string is pushing the balloon backwards. There is a higher density of air at the back of the van, which causes the helium balloon to be pulled towards the back of the van. Nothing is forcing it backwards, as the van accelerates forwards the balloon naturally wants to remain where it was in the Earth frame of reference, according to Newton's first law of motion. There is a higher density of air at the front of the van, which causes the helium balloon to be pushed away from the front of the van.

A balloon is tied to the floor of a minivan. Currently, the balloon isn't going straight up like normal, but is instead bending towards the back of the van. This is because... The van is accelerating forwards (speeding up). The van is accelerating backwards (slowing down/braking). The van is at rest. The vehicle is moving forward at a constant velocity. MA The vehicle is moving backward at a constant velocity (reversing).
