Gravity is pulling everything down. The hot air in the balloon is less dense than the surrounding air, so the air forces it up through what is called buoyancy. Any air movement will shove the balloon in the direction that air is moving. The balloon will be carried along 'cause there's nothing to stop the air from doing that. Just think about what is happening and it will lock in. Gravity, the wind (moving air) and the conversion of chemical energy in fuel into thermal energy to heat the air in the balloon and give it lift through buoyancy. Simple and easy physics.
What else can I help you with?
What is the net force of a balloon?
The net force on a balloon is the sum of all forces acting on it, such as gravity, buoyancy, and any external forces like wind. If the balloon is in equilibrium, the net force is zero, meaning all forces are balanced. If the balloon is accelerating or moving, then the net force is non-zero and determines the direction of motion.
When are all the forces acting upon an object balanced?
All forces acting upon an object are balanced when the net force on the object is zero. This occurs when the vector sum of all the forces acting on the object in any direction is zero, resulting in the object either being at rest or moving at a constant velocity.
Is an object in equilibrium moving?
An object in equilibrium is not moving, as all the forces acting on the object are balanced. If the object were to be in motion, it would no longer be in equilibrium as there would be an unbalanced force acting on it.
What is force acting on a body with uniform motion?
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
What is the direction of the force acting on the balloon?
The force in an inflated balloon is exerted outward equally in all directions.
What is the net force of a balloon?
The net force on a balloon is the sum of all forces acting on it, such as gravity, buoyancy, and any external forces like wind. If the balloon is in equilibrium, the net force is zero, meaning all forces are balanced. If the balloon is accelerating or moving, then the net force is non-zero and determines the direction of motion.
If an object is moving at constant velocity what is the sum of all of the forces acting on the object?
zero
When are all the forces acting upon an object balanced?
All forces acting upon an object are balanced when the net force on the object is zero. This occurs when the vector sum of all the forces acting on the object in any direction is zero, resulting in the object either being at rest or moving at a constant velocity.
What are all the objects in the universe doing?
They are just sitting there, moving and changing according to the forces that are acting on them.
Is an object in equilibrium moving?
An object in equilibrium is not moving, as all the forces acting on the object are balanced. If the object were to be in motion, it would no longer be in equilibrium as there would be an unbalanced force acting on it.
What is force acting on a body with uniform motion?
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
When does a moving object accelerate?
An object accelerates when all the forces acting on it don't add up to zero.
What is the direction of the force acting on the balloon?
The force in an inflated balloon is exerted outward equally in all directions.
An object is moving with constant velcity and it is not accelering. Can it have any forces acting on it?
Yes, that's possible, as long as the vector sum of all such forces is zero.
If the sum of all the forces acting on a car is zero then the speed of the car always?
If the sum of all the forces acting on a car is zero, it means that the car is in a state of equilibrium. In this case, the car will either be at rest or moving at a constant speed. If the car is already moving at a certain speed, it will continue to move at that speed due to the balance of forces acting on it.
What is the test for whether or not a moving object is in equilibrium?
If a moving object is in equilibrium, the vector sum of all forces acting on it is zero. This can be determined by analyzing the forces acting in all directions (horizontal and vertical) to see if they balance out. If the net force is zero, the object is in equilibrium.
Ability to stay at rest or to keep moving?
Inertia
