A container is filled with a liquid and there is a bubble in the container. Why will the bubble move in the direction of the force if it is moved forward suddenly?

It's not so much the bubble moving towards the force, but the more dense liquid is moving away from it. Newtons First law of Motion states that object in motion or at rest tend to stay in motion or at rest respectively.
As you accelerate a fluid with a gas bubble, the fluid's inertia will want to keep it still, so it flows away from the direction of the acceleration. The fluid is more dense than the gas, so it has more mass, which means it has more inertia.
So as inertia resists the acceleration in the fluid and "pulls" it away from the acceleration, the bubble gets pushed towards it.

Thats all about newtons law of inertia. Inertia explains how something(say a person on a bus) is moving with the bus, but when the bus stops suddenly, the person leans forward or slides forward.tahst because the bus stops but the person doesnt. so the bubble is in the liquid and the liquid is moved, the bubble doesnt move too, it trys to stay where it was.

Ethernay and Mark B are on the right path, the acceleration of the container changes the direction of the fluid's pressure gradient from vertical to slanted. The bubble will then suffer more pressure from on side than the other.

I am not a scientist..but I will try to explain what I feel about it..
OK..Ever heard of "inertia"??The thing that happens when you move a leaf of a plant which has droplets on it..the drops fall down..Tis kinda the same thing..Each and every parcticle is attracted to the center of gravity of the object..When jerked , the substance's stabilty is disturbed..and the substance tries to maintain its earlier form or tries to remain rooted to the spot..But..well..it is not possible as the force at which it is jerked is more than it can handle..The bubble is gas..and oil is liquid..So the friction between the oil surface and the gaseous surface is diffrent from the friction between the same form of matter..ie..oil-oil ..or.. liquid-liquid..So..Because of this,Gas which is lighter than liquid..gets displaced more due to lesser friction than liquid-liquid..Well..So..there you have it..

Because it weighs less than the liquid. The heavy liquid is pushed backwards, and forces the bubble forwards.

the bubble will move upward since the density of the bubble is less then that of the liquid.
