The two forces acting on a hot air balloon that is floating are buoyant force, which pushes the balloon up, and gravity, which pulls the balloon down. These two forces are in equilibrium, allowing the balloon to float at a constant altitude.
When a book is dropped, the main forces acting on it are gravity pulling it downward and air resistance pushing against it as it falls through the air.
The forces acting on a moving object include: gravity, friction, air resistance, and any applied forces such as pushing or pulling. These forces can affect the speed, direction, and motion of the object.
Gravity (downwards), and air resistance (upwards).
In a free body diagram of a roller coaster, the forces acting on it are gravity, normal force, friction, and air resistance.
The main forces acting on a kite are tension in the string or line that holds the kite in the air and aerodynamic forces such as lift and drag from the wind. Gravity also acts on the kite, pulling it downward.
The forces acting on the bike is gravity, air resistance and friction.
