The answer is gravity.they also experience a upward force called air resistance
up thrust or air resistance.
Air friction, which is measured as drag.
Drag is the force that slows down a plane. Drag may be caused by air friction. It may also caused by non-retractable landing gears.
air resistance , maybe!
i think air resistance slows down the object that gravity is pulling towards it
Air resistance.
drag force (frictional force exerted by air) or air reststance
Air resistance slows down the object. The kinetic energy accelerates the object. Friction creates a reaction between the surface and the object.
Whenever any object moves through air (eg an aeroplane) it observes four forces 1 Drag force 2. lift force 3.weight of object 4.thrust created by the propellers or engine of the object. The drag force is directed opposite to the direction of moment of the object and slows the object down.
Causes drag( slows an object), can cause lift or down force. It can also cause an object trajectory (wind drift of a rifle bullet)
Air resistance or upthrust :)
'Drag' which is air resistance.
it slows down their speed
Air Resistance or friction with the air.
up thrust or air resistance.
Air friction, which is measured as drag.
