Concept explainers

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

Moment of a Force

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…

Chapter 11, Problem 18PCE

A motorcycle accelerates from rest, and both the front and rear tires roll without slipping. (a) Is the force exerted by the ground on the rear tire in the forward or in the backward direction? Explain. (b) Is the force exerted by the ground on the front tire in the forward or in the backward direction? Explain. (c) If the moment of inertia of the front tire is increased, will the motorcycle’s acceleration increase, decrease, or stay the same? Explain.

The figure below shows a uniform disk, with mass M = 4 kg and radius R = 0.2 m, mounted on a fixed horizontal axle. A block with mass m = 0.5 kg hangs from a massless cord that is wrapped around the rim of the disk. The cord does not slip, and there is no friction at the axle. 1. Find the acceleration of the falling block? 2. Find the tension in the cord?

CONCEPTUAL Physics- NEXT-TIME QUESTION 6). A marble rolling on a horizontal surface encounters an incline and rolls up it without skidding until it comes to a stop. Then it rolls back down again, also without skidding. The force on the marble due to its interaction with the incline has two components-one perpendicular to the incline (the normal force) and one parallel to the incline (a frictional force). The frictional force on the marble is directed down the incline for the upward roll and up the incline for the downward roll. b) up the incline for the upward roll and down the incline for the downward roll. up the incline for the entire trip. down the incline for the entire trip. c) d) Consider sliding on a slippery slope vs rolling!

A child is sitting 1.50 m from the center of a wooden, circular, rotating disk. The coefficient of static friction between the child and disk is 0.30. What is the maximum speed the child can have before slipping off the disk?
