## Are there forces acting on the ball?

The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.

## What forces are involved in golf?

Two types of forces are important to the golf swing: normal forces and shear forces. Normal forces are illustrated in the linear components of the swing, and shear forces are illustrated in the rotational components of the swing. Normal forces are applied by the feet downward or perpendicular to the ground.

## What forces are acting on the golf tee when it is at rest on the hoop?

Explanation: Free Body Diagram for when the Ball Rests on the Tee: There is a force of gravity pushing down on the object 100% of the time and a force of the normal pushing back upward with the equal and opposite force of the gravitational force.

## What are two examples of objects at rest?

The examples of rest include: sleeping, sitting, standing, staring, lying, a fixed clock, bottle kept on a table, a stopped car.

## Which has more inertia a golf ball or a bowling ball?

The bowling ball has more mass, so it has more inertia. The bowling ball needs more force to move at the same speed as the golf ball because it has more inertia.

## What objects have the greatest inertia?

The tendency of an object to resist a change in velocity is known as the object’s inertia. For example, a train has significantly more inertia than a skateboard.

## Which is more inertia?

Inertia is the measure of the mass of the body. The greater is the mass of the body; the greater is its inertia and vice-versa. (a) Mass of a stone is more than the mass of a rubber ball for the same size. Hence, inertia of the train is greater than that of the bicycle.

## What factors can decide the inertia of a body?

Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed. Momentum will be discussed in a later unit.

## Which factors does the inertia of rest depend on?

Inertia depends on density and mass. Inertia is directly proportional to mass and density of an object. More the mass of an object, more is the inertia of the body.

## What factors affect rotational inertia?

Indeed, the rotational inertia of an object depends on its mass. It also depends on the distribution of that mass relative to the axis of rotation. When a mass moves further from the axis of rotation it becomes increasingly more difficult to change the rotational velocity of the system.

## On what factors radius of gyration depends?

On what factors radius of gyration depends? Some of the factors that influence the value of the radius of gyration are the size and shape of the body, configuration of the rotational axis and position. It also depends on body mass distribution with respect to the rotational axis.

## Does radius of gyration depends on angular velocity?

Solution : We know that K=√IM,I∝M hence radius of gyration does not depends upon mass of the body. A uniform rod of length l is spinning with an angular velocity ω=2vl while its centre of mass moves with a velocity v.

## Does the radius of gyration depends upon the speed of rotation of the body?

Radius of gyration of a body is not affected by speed of the body.

## What is radius of gyration in bar pendulum?

Radius of gyration or gyradius of a body about an axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body’s actual distribution of mass, if the total mass of the body were concentrated there.

## What is the least radius of gyration?

The smallest value of the radius of gyration is used for structural calculations as this is the plane in which the member is most likely to buckle. Square or circular shapes are ideal choices for columns as there is no smallest radius of gyration. They have the same value because the radius is constant.

## What is the formula of radius of gyration K?

Mechanics: Here radius of gyration about an axis of rotation is calculated using mass moment of inertia and its formula is given by relation, k=√IM(1) (1) k = I M This equation (1) is the radius of gyration formula for mass moment of inertia.

## What is the formula of radius of gyration Mcq?

Explanation: The radius of gyration of a body about an axis is a distance such that its square multiplied by the area gives moment of inertia of the area about the given axis. The formula of radius of gyration is given as k2 = I/A.

## What is radius of gyration Class 11?

Radius of gyration is generally defined as the distance from the axis of rotation to a point where total mass of any body is supposed to be concentrated, so that the moment of inertia about the axis may remain same. Simply, gyration is the distribution of the components of an object.

## What is the moment of inertia of a circular section *?

Moment Of Inertia Of A Circle Here, r is the radius and the axis is passing through the centre. This equation is equivalent to I = π D4 / 64 when we express it taking the diameter (D) of the circle.

## What is parallel axis theorem and to whom it is applied *?

What is parallel axis theorem and to whom it is applied? Explanation: Parallel axis for any area is used to add the two mutually perpendicular moment of inertias for areas. It gives a moment of inertia perpendicular to the surface of the body. That is the moment of inertia perpendicular to the surface in considerance.

## What is unit of radius of gyration?

The unit of the radius of gyration is mm. From the above equation, we can infer that the radius of gyration can also be defined as the root-mean-square distance of various particles of the body from the axis of rotation.

## What is the parallel axis theorem used for?

The parallel axis theorem, it also known as Huygens–Steiner theorem, or just as Steiner’s theorem, named after Christiaan Huygens and Jakob Steiner, can be used to determine the moment of inertia or the second moment of area of a rigid body about any axis, given the body’s moment of inertia about a parallel axis …

## What is the unit of moment of inertia?

The unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square.

## What is moment of inertia in simple terms?

), also called “angular mass” (kg·m2), is the inertia of a rotating body with respect to its rotation. It is a rotating body’s resistance to angular acceleration or deceleration, equal to the product of the mass and the square of its perpendicular distance from the axis of rotation.

## What is the unit of MI?

The mile is an English unit of length of linear measure equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959.
