Because the force generated is always opposite the direction of motion.
The general tendency is for resistance to oppose movement.
Asteroids have a constant speed in a vacuum if there isnt anything else affecting it such as gravity or by colliding with other things. If it was to be in the earths atmosphere then the air would cause a resistance and slow it down :) hope this helps
It is the action of friction that slows something moving through air. The larger the object, the more the air resistance acting on the object.
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
they slow down
The air molecules slow down and it deflates.
A parachute
Air resistance and friction. Weight can sometimes slow you down if your going up in like a plane or rocket. UpTHRUST THRUST=Push
A parachute is slowed down by air resistance.
Air resistance is the force acting on an object moving in air that tends to slow it down or produce drag. If a stone is falling, air resistance will be acting on it to try to slow it. Should we consider a jet moving through air, air resistance will be providing drag to slow the jet down.
It is using air resistance to slow an object down.
Yes
slow everything down
Air resistance and ultimately the ground.
Air Resistance or friction with the air.
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
