Two thing slow the balloon down. First, air friction opposes its upward movement. Second, as the balloon gets higher, the air around it gets less dense, so there's not as much force propelling the balloon upward.

When a person stops pedaling the bicycle slows down what force is this?
air Resistance is proportionate to velocity squared, so air resistance is dominant over a certain speed, but below that speed it will be rolling resistance that is the biggest factor. At 12mph, 80% of your effort goes into overcoming air resistance on a cycle.
Why the tires of an aeroplane are made of a conducting rubber?
Because the friction between the aero plane and ground then when there is enough friction it goes up and when it goes down there enough friction
How does friction change how far a car goes?
Friction does work to slow down the car. Thus, the more friction there is, the less distance a car can go.
When you rub a balloon on your hair what goes from your hair to the balloon?
Electrons move between the hair and the balloon.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
What is an example for friction using bowling balls?
Two come to mind, the ball slows down as it goes further down the alley. as the ball spins, the friction generated causes the ball to curve.

Is it true the faster it goes the faster it slows down?
no!
What stops Frisbee from flying endlessly?
Air friction slows its forward momentum, and when it goes slower, it doesn't push enough air downwards to stay aloft, and gravity pulls it down.
What if the heat source in a hot air balloon goes out?
what goes up, goes down!
What are disadvantages of friction with examples?
Friction produces unnecessary heat leading to the wastage of energy.The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.Forest fires are caused due to the friction between tree branches.A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.
What keeps an object stopping?
Friction. Friction is usually when some force is rubbing against the object. An example is how when you activate the breaks of a car that it would stop because their is this device that goes against the tire to cause it to stop. The heat from the friction generally slows down the object while also applying force to the object.
What friction slows a roller coaster down?
Brakes are used to slow down roller coasters. The brakes simply contract together against part of the car and friction brings them to a halt. Another type of roller coaster brake are magnets. The magnets have a force between them that slows the car down.
Why does a car slow down when you accelerate?
A car goes faster when you accelerate. It slows down when you brake.
What happens when the hot air in the balloon cools?
it goes down
Why the tires of an aeroplane are made of a conducting rubber?
Because the friction between the aero plane and ground then when there is enough friction it goes up and when it goes down there enough friction
As that gas slows down to turn into a liquid it goes through what proccess?
Condensation.
