When object in elevator and elevator is falling downward then gravity is acting on it but why it is said that in this condition object is weightless?
In a falling elevator, both the elevator and the object inside are accelerating downwards at the same rate under gravity. This creates the sensation of weightlessness, as the object is not experiencing any resistance or contact force from the elevator floor. However, gravity is still acting on the object, causing it to accelerate downwards at the same rate as the elevator.
When an object is in freefall what does it mean?
Freefall refers to the motion of an object falling solely under the influence of gravity, with no other forces acting on it except air resistance. During freefall, the only force acting on the object is its weight, causing it to accelerate downwards at a constant rate of 9.81 m/s^2 (due to gravity).
What is correct for an object released from rest at a certain height?
The object will fall freely under the influence of gravity. Its initial velocity will be zero, and it will accelerate downwards until it reaches the ground. The time taken for the object to fall and its final velocity can be calculated using kinematic equations.
Can an object with mass be weightless while under the influence of gravity?
No, an object with mass will always experience the gravitational force, so it cannot be truly weightless when under the influence of gravity. Weight is the measure of the force of gravity acting on an object, so as long as gravity is present, the object will have weight.
What type of motion is a free fall?
Free fall is a type of motion where an object falls under the influence of gravity with no other forces acting upon it. During free fall, the object accelerates downwards at a constant rate of 9.8 m/s^2 on Earth.

What is a falling object under the influence of only gravity in?
A falling object under the influence of only gravity is in free fall. This means that the object is accelerating downward due to the force of gravity, without any other forces acting upon it.
What does a stingray fall under?
It falls under water and the effect of gravity.
What is falling body?
is an object that moves under gravity only.
What is the formula for calculating the velocity of an object falling freely under gravity, expressed as v2/2g?
The formula for calculating the velocity of an object falling freely under gravity is v2/2g, where v represents the velocity of the object and g represents the acceleration due to gravity.
What is the aim of rainwater?
Downwards, but vectored by the wind. Rain falls under the influence of gravity but its path down is modified by the force of the wind.
What is the formula for calculating the velocity of an object falling freely under gravity, considering the acceleration due to gravity as 2g?
The formula for calculating the velocity of an object falling freely under gravity, considering the acceleration due to gravity as 2g, is v (2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height from which the object falls.
What is the meaning of free fall when it comes to physics?
Free fall in physics refers to the motion of an object falling under the influence of gravity alone, without any other forces acting on it. During free fall, the only force acting on the object is the force of gravity, causing it to accelerate downwards at a constant rate of 9.81 m/s² near the Earth's surface. The object is said to be in free fall as long as air resistance or other forces are negligible.
