The centripetal force of a body having mass m and rotating at a linear speed of v in a circle of radius r is given by mvr mvr mv2r mvr2?
none of the above
Force centripetal = (mass * velocity^2) ÷ radius
More mass , more force needed to keep object in the circle
Object going faster, more force needed to keep object in the circle
Larger radius, less force needed to keep object in the circle
That is why mass and velocity are in the numerator ( multipliers)
and Radius is in the denominator ( divider)

How many linear feet in a 2 foot diameter circle?

Hoe to calculate velocity of a rotating member?
rotation is normally rpm (revolutions per minute) , velocity of a particular point around an axis, example : distance from axis = 1 m , rpm = 10 000 circumference of 1m circle = 1m*2*pi (3.14159) = 6.28318 (meters) * 10 000 rpm = 62 831.8 meters/min = 1 047.197 meters / sec
What is anguler momentum?
Angular momentum is a property of a rotating object that describes its tendency to keep rotating. It is calculated as the product of an object's moment of inertia and its angular velocity. Similar to linear momentum, angular momentum is conserved in the absence of external torques.
Is CO2 a linear molecule?
Yes it is an aliphatic hydrocarbon with a C triple bond C
What is the unit used to measure distances around a circle?
Radian is the unit used to measure distances around a circle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
Can centripetal force produce rotation?
Yes, centripetal force is required to maintain rotational motion by pulling an object towards the center of the rotation. Without centripetal force, the object would move in a linear path rather than rotating.
How does radial acceleration relate to linear acceleration in a rotating object?
Radial acceleration and linear acceleration are related in a rotating object because radial acceleration is the acceleration towards the center of the circle due to the change in direction of velocity, while linear acceleration is the acceleration along the tangent to the circle due to the change in speed. In a rotating object, both types of acceleration work together to determine the overall motion of the object.
What is the centrificall force of a 24 inch circle at 845 rpms?
To calculate the centripetal force acting on an object moving in a circle, you can use the formula ( F = m \cdot \frac{v^2}{r} ), where ( F ) is the centripetal force, ( m ) is the mass of the object, ( v ) is the linear velocity, and ( r ) is the radius of the circle. For a 24-inch circle, the radius ( r ) is 12 inches (1 foot). First, you need to convert the RPM to linear velocity using the formula ( v = 2\pi r \cdot \text{(RPM/60)} ). After calculating the linear velocity, you can plug it into the centripetal force formula along with the object's mass to find the force.
Does a circle represent a function in linear functions?
a) A circle is not the graph of a function. b) A circle is not linear.
How can one determine the angular velocity from linear velocity?
To determine the angular velocity from linear velocity, you can use the formula: Angular velocity Linear velocity / Radius. This formula relates the speed of an object moving in a circular path (linear velocity) to how quickly it is rotating around the center of the circle (angular velocity).
Is a circle non-linear?
No, but it is non-linear.
How many linear feet are in a 43 foot diameter circle?
43 linear feet. The diameter of the circle is the longest distance that you can have in the circle.
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.
What does the linear speed of a rotating object depend on?
The linear speed of a rotating object depends on its angular speed (how fast it rotates) and the distance from the axis of rotation (the radius). Linear speed is calculated as the product of the angular speed and the radius.
What is the formula to calculate the linear velocity of a wheel when it is rotating at a given angular velocity?
The formula to calculate the linear velocity of a wheel when it is rotating at a given angular velocity is: linear velocity radius of the wheel x angular velocity.
Is linear acceleration the same as the tangential acceleration in circular motion?
No, linear acceleration refers to changes in speed along a straight line, while tangential acceleration refers to changes in speed along the circumference of a circle in circular motion. In circular motion, objects experience both tangential and centripetal accelerations.
What is the relationship between angular velocity and linear velocity in a rotating object?
The relationship between angular velocity and linear velocity in a rotating object is that they are directly proportional. This means that as the angular velocity of the object increases, the linear velocity also increases. The formula to calculate the linear velocity is linear velocity angular velocity x radius of rotation.
