What happens to the acceleration and velocity when an object in free fall moves downward?
In free fall, the acceleration of the object remains constant at 9.8 m/s^2 directed downward towards the center of the Earth. The object's velocity will increase as it falls due to the constant acceleration, until it reaches terminal velocity if air resistance is present.
Is it true that the acceleration of an object is constant?
No, the acceleration of an object is not always constant. An object can have a variable or changing acceleration depending on the forces acting upon it. For example, an object in free fall has a constant acceleration due to gravity, while an object experiencing friction will have a changing acceleration.
What happens to an object acceleration as it goes from free fall to terminal velocity?
As an object falls freely, its acceleration remains constant at approximately 9.8 m/s^2 until it reaches terminal velocity. Once it reaches terminal velocity, the acceleration becomes zero as the forces acting on the object balance out, resulting in a constant velocity.
Can an object in free fall has a constant momentum?
Yes, an object in free fall can have a constant momentum if no external forces are acting on it. In free fall, the only force acting on the object is gravity, which causes a constant acceleration. As long as no external forces are present, the momentum of the object will remain constant.
Why the acceleration of an object in free fall does not depend on the mass of the object?
The acceleration of an object in free fall is mainly determined by gravity, which is a constant force acting on all objects regardless of their mass. Therefore, the acceleration of an object in free fall is the same for all objects, regardless of their mass. This is because the force of gravity accelerates all objects equally, leading to a constant acceleration of approximately 9.8 m/s^2 on Earth.
Why the acceleration is constant in free fall?
Acceleration is constant in free fall because gravity is the only force acting on the object, and it is a constant force that always points downward towards the center of the Earth. This constant force results in a constant acceleration of 9.81 m/s^2 near the surface of the Earth.
What is the rate of acceleration an object encounters in free fall?
In free fall, objects experience an acceleration of approximately 9.8 m/s^2, due to the force of gravity pulling them downward. This rate of acceleration is constant and independent of the mass of the object.
An object in free fall what happens until it reaches terminal velocity?
During free fall, an object accelerates at a constant rate due to gravity. As the object falls, air resistance increases, causing the acceleration to decrease. Eventually, the object reaches terminal velocity, where the air resistance equals the gravitational force, resulting in a constant velocity.
When does an object fall at a constant rate of acceleration?
An object falls at a constant rate of acceleration when it is in a vacuum or when air resistance is negligible. In this case, the only force acting on the object is gravity, causing it to accelerate towards the ground at a constant rate of 9.81 m/s^2 (on Earth).
What do you call the motion of an object with a constant acceleration?
Free fall. Airbus has built aircrafts that may dive with an acceleration of 9.81 m/s2 to simulate zero gravity. satellites are technically in a constant free fall. A world where no friction would occur would lead to constant acceleration as long as the force acting on the object stays the same.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
What is the magnitude of the acceleration of an object in free fall near earth's surface?
The magnitude of acceleration of an object in free fall near the Earth's surface is approximately 9.81 m/s^2. This acceleration is due to gravity and causes the object to accelerate downward at a constant rate.
