When is an object that has been dropped from a great height to the air closest to being in freefall?
An object is closest to being in freefall right before it hits the ground, when air resistance has slowed it down such that its acceleration is primarily due to gravity. At that point, the object's speed is nearly constant and it is falling solely due to the force of gravity.
What appears to be happening to an object in free fall?
An object in free fall experiences a constant acceleration due to gravity, causing it to increase in velocity as it falls. The object's speed and distance traveled increase over time, with no air resistance, until it hits the ground.
What happens to an object in free fall near Earth's surface?
If air resistance can be neglected, the object will fall faster and faster. If air resistance is significant, the object will fall faster and faster, until it asymtotically approaches a "terminal velocity" - the velocity at which the downward pull of gravity is in equilibrium with the air resistance.
What is the weight of a rock after it hits the ground?
The weight of a rock remains the same after it hits the ground. Weight is determined by the mass of an object and the gravity acting on it, and these factors do not change when a rock hits the ground.
What happens when a small object hits earth's gravity?
Generally it falls into the atmosphere and burns up.
Why a falling object to earth's gravity does not continue forever?
Once it hits the Earth's surface, it will stop falling.
Does the speed of an object in air continue to increase until it hits the ground?
It depends on how high it is when it start falling. If it is high enough, it will reach its terminal velocity and stop accelerating before it hits the ground. As an object is falling, it has to push through air below it. The faster it falls, the greater the air resistance (or drag) to the object. At some point, the amount of air resistance will be equal to the pull of gravity (its weight) and it will not be able to go any faster. We call this its terminal velocity, the maximum speed it can reach as it is falling through air. A larger or wider object will have more drag than a smaller object of the same weight and will have different maximum speeds. That is why a person falling from a plane with a parachute will stop going faster after the parachute opens and the drag increases because of the shape of the open parachute.
What is the property that describes an object's resistance to changing its motion is what?
The light hits its own motion to make its speed
As an object falls freely in a vacuum its?
velocity increases as it falls due to the force of gravity acting on it. Since there is no air resistance in a vacuum, the object will continue to accelerate until it reaches its terminal velocity or hits the ground.
What happens to the speed of an object when it is thrown up in the air and when it comes back down?
an object thrown into the air will slow down as it ascends higher into the air until it stops ascending and the speed of the object increases as it falls until it reaches its terminal velocity in air. As an object passes through air, it encounters air resistance which slows down an object moving freely through air. An object will be moving at a slower speed when it hits the ground than it did when it was thrown into the air due to this air resistance.
Velocity time graph for a body dropped from a certain height?
The velocity-time graph for a body dropped from a certain height would show an initial spike in velocity as the object accelerates due to gravity, reaching a maximum velocity when air resistance equals the force of gravity. After this, the velocity would remain constant, representing free fall with a terminal velocity. When the object hits the ground, the velocity suddenly drops to zero.
When air resistance balances weight the velocity becomes?
Terminal. It stays at that one velocity til the object hits the ground.
