Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, fo…

Textbook Question

Chapter 8, Problem 44EAP

A charged particle of mass m moving with speed v in a plane perpendicular to a magnetic field experiences a force F → (qvB. perpendicular to v → where q is the amount of charge and B is the magnetic field strength. Because the force is always perpendicular to the particle’s velocity, the particle undergoes uniform circular motion. Find an expression for the period of the motion. Gravity can be neglected.

Chapter 8, Problem 45EAP

Students have asked these similar questions

A firefighter, whose mass (including clothing and equipment) is m = 105kg, hears the alarm and slides down the pole with a constant downward acceleration of magnitude a = 3.92 meters per squared second.What would the expression for the magnitude of the force F, exerted on the firefighter by the pole be? Especially in terms of the variables from the problem statement as well as g for the acceleration due to gravity.

Two small spacecraft, each with a mass m = 2000 kg, are in orbit circular Earth, at an altitude h of 400 km. Igor, the commander of one of the ships, arrives at any fixed point in orbit 90 s ahead of Picard, the commander of the other ship. What are the (a) periods T0 and (b) the speed v0 of the ships? At point P, Picard shoots an instantaneous burst in the forward direction, slowing your ship by 1.00%. After this explosion, the elliptical orbit follows, which is shown discontinuous in the figure. What are (c) the kinetic energy and (d) the potential energy of your ship immediately after the explosion? In Picard's new elliptical orbit, what are (e) the total energy E, (f) the semi-major axis a, and (g) the orbital period T? (h) How long before Igor will return Picard to P? Since you can only ansewer to 3 sub-parts, I'll ask here (a,b,c) and submit another question for (d,e,f), (g,h). Thanks.
