"Terminal" velocity.
a falling object accelerates 32ft per second per second
terminal velocity
Gravity is a force that accelerates the falling object towards the ground.
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.
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
If the parachutist is just falling down vertically, he is falling because of the unbalance force. Gravity is pulling him down. Gravity is stronger than the air resistance that is "keeping him up". The two unbalanced forces: gravity & air resistance. Because they are imbalance, he is accelerating towards the Earth's surface at 9.8 meters per second.
The object accelerates downwards in response to the attractive force of gravity.
Gravity and air resistance.
The forces acting on a falling body are gravity and air resistance.
Gravity and air resistance.
Objects when falling that cannot ignore air resistance are things like feathers, leaves, seeds, or small pieces of paper just to name a few. Objects when falling that can ignore air resistance are things such as objects that are heavy and compact like rocks or metal balls.
When an object is falling, it accelerates, so it is speeding up. The faster it goes, the more air resistance there is on the object. Eventually, the force of the air resistance pushing up on the object will equal the force of gravity pushing down on the object. The forces on the object are balanced (they cancel out), so it will have no acceleration. This causes terminal velocity; the object is not speeding up anymore. When the forces on an object are balanced, it has no acceleration. This does not mean it has no velocity, it just means that the velocity is not changing (it does not speed up or slow down.)
