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.
What is the relationship between the normal force and the apparent weight of an object in an elevator?
The normal force in an elevator is equal to the apparent weight of an object. As the elevator moves up or down, the normal force changes, affecting the apparent weight experienced by the object.
How can the linear momentum of an object be calculated?
The linear momentum of an object can be calculated by multiplying the mass of the object by its velocity. The formula for linear momentum is: momentum = mass x velocity.
What is a linear object?
A linear object is an object that has a length, but negligible width and height, making it one-dimensional. Examples include lines, rods, and strings. These objects are characterized by having uniform thickness along their length.
What is the formula of linear momentum?
linear momentum=product of mass and velocity

Is lift and elevator are terms for the same object?
Yes. Americans call Englands' lift an elevator.
What is the rate of motion of an object in a linear object?
That is the object's 'speed'.

What is the rate of motion of an object in linear motion?
That is the object's 'speed'.

What is linear acceleration and how does it relate to the motion of an object?
Linear acceleration is the rate at which an object's velocity changes over time in a straight line. It is a measure of how quickly an object is speeding up or slowing down. Linear acceleration is directly related to the motion of an object because it determines how fast the object is moving and in what direction.
What is the formula for calculating the linear mass density of a one-dimensional object?
The formula for calculating the linear mass density of a one-dimensional object is mass divided by length. It is represented as m/L, where is the linear mass density, m is the mass of the object, and L is the length of the object.
How does the angular acceleration of a rotating object relate to its linear acceleration?
Angular acceleration and linear acceleration are related through the radius of the rotating object. The angular acceleration is directly proportional to the linear acceleration and inversely proportional to the radius of the object. This means that as the linear acceleration increases, the angular acceleration also increases, but decreases as the radius of the object increases.
How is angular acceleration related to linear acceleration in a rotating object?
Angular acceleration and linear acceleration are related in a rotating object through the equation a r, where a is linear acceleration, r is the radius of the object, and is the angular acceleration. This equation shows that the linear acceleration of a point on a rotating object is directly proportional to the angular acceleration and the distance from the center of rotation.
