(1) What is centrifugal force and how is it related to centripetal force?

(2) When the centripetal force and mass of a rotating body are held constant, what will to happen to the period (T) if the radius of rotation is increased?

Homework Answers

Answer #1

1) centrifugal force is the apparent force felt by a body in circular motion that acts outwardly away from the center of mass.

When we consider the centripetal force as an action , according to newtons third law there is an equal and opposite reaction.This reaction is the centrifugal force.

2) We have F=ma=mrw^2

Since centripetal force is kept constant, Mrw^2 will also be constant.so if radius,r increase then w^2(w=omega)decreases.

W^2 decreases means that angular velocity decreases , therefore the time period increases.

A single axis accelerometer is mounted on a rotating wheel so that its measurement axis is along a radius vector which is perpendicular to the wheel’s axis of rotation at a distance, R. The wheel’s rotation axis is tilted at an angle θ from the local vertical direction in a constant gravity field, ?⃗. For example, at θ = 0, the wheel’s rotation axis is aligned with ?⃗ and the accelerometer’s measurement axis is in the local horizontal plane (perpendicular...

A pulsar is a rapidly rotating neutron star that emits radio pulses with precise synchronization, there being one such pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. At present, the pulsar in the central region of the Crab nebula has a period of rotation of T = 0.16000000 s, and this is observed to be increasing at the rate of 0.00000943 s/y.

1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...
