If the balloon accelerates (changes its speed), then that means that forces act on it. If any object "does not follow" Newton's First Law, that means that the conditions are not fulfilled - the conditions being that no net force acts on an object.
It is a disordered motion.
The helium atoms move quickly in all directions. This is cap
absolute zero is the theoretical temperature at which all atomic motion stops (except for some atomic vibration).
Particles of a gas are in a disorderly motion (Brownian).
number one the kinetic theory states that the particles of all matter are in constant , random motion. So the balloon bursting is caused by the excessive (so many) particles in the balloon. Ur welcome Lola :P
It appears to move in the opposite direction to the motion of the van

It is periodic motion
It is the first law of motion.
It is a disordered motion.

When applying the brakes, the car is decelerating. Everything in the car, the people in the car, packages in the car, the balloon in the car and the air in the car, will tend to stay in motion. This is because an object in motion tends to stay in motion, according to Newton. However, there is a second effect. Because the air in the car tends to stay in motion, it will continue to move forward It will be compressed at the front of the car and made less dense at the back. This means the air nearer the front of the car will be at higher pressure than the air at the back. Looking at the small bit of air around the balloon this means there will be more pressure on the front of the balloon than the back. This imbalance of pressure means there is a net backwards force on the balloon. Both effects are present on the people, the packages and the balloon, too. The differential air pressure is pushing the people and packages backwards as well. It is just that people are quite dense (have a lot of mass per cubic inch), and helium balloons are very low in density (have very little mass per cubic inch.) This means the first effect will be much bigger than the second for people and packages. The second effect will be a bit bigger than the first for a helium balloon The net result is that people and packages will be "moving forward" because of their inertia, and the balloon will be "pushed backwards" because of the higher air pressure in the front of the car. In fact, we can predict which object will go forwards and which will go backwards. It depends if they have higher density than air (are lighter than air). When a car is braking, anything goes forward in the car if the density of the object is greater than air. Helium is one of the few gases which is lighter than air, so a helium balloon always floats in the air, and it will "float" backward.
Anything can change the way an object moves and acts. For example...if we addedhelium to a balloon, the ballon would act differently. The balloon would move upwardin a different direction than if we didn't add helium. I had to think on that one! lol===============================Answer #2:In order to change an object's motion ... speed or direction ... a net forcemust act on it."Net force" means that when you add up all the forces acting on it, theydon't add up to zero.There's no other way to change an object's motion. Even the situation described inAnswer #1 up above involves adding a force to the balloon. When you add helium toit, the pressure inside the balloon increases. That makes the volume increase, whichdisplaces more air. Displacing more air in turn increases the upward buoyant forcethat the surrounding atmosphere exerts on the balloon.
If you need a one word answer, then I think "buoyancy" is what you're looking for. Buoyancy is caused by falling air pressure with altitude. Air pressure at sea level is over 14.7 pounds per square inch (2000 pounds per square foot!). You can feel this pressure by pulling on a suction cup. Because air pressure drops with altitude, the force from air on the top of an object is less than on the bottom. If the object has very low density (such as a helium-filled balloon), this difference in force is enough to push the object up.
since the balloon is moving up with a constant speed it is not accelerated or decelerated
The structure of the airship is based on a metal alloy frame. Lift is provided by multiple internal balloons or cells filled with gas that is lighter than air (hydrogen or helium). Forward motion is driven by propeller engines. Steering is accomplished by means of fins.
This is Newton's Third Law: For every action, there is an equal and opposite reaction.
