An electric motor drives a machine through a speed reducing gear of ratio 9:1. The motor armature, with its shaft and gear wheel, has moment of inertia 0.6 kg-m2. The rotating part of the driven machine has moment of inertia 45 kg-m2. The driven machine has resisting torque of 100 N-m and the efficiency of reduction gear is 95%. Find the power which the motor must develop to drive the machine at a uniform speed of 160 r.p.m.

Kinematics & Kinetics of Motion topics include: K and kinetics of motion, linear velocity and acceleration, numericals on kinetics of motion, kinetic energy loss during elastic impact, relation between linear and angular motion.

Kinetics and kinematics are both branches of physics that study the motion of an object. Kinetics studies the forces that cause an object's motion, while kinematics studies the motion itself. 

Kinetics: Studies the forces that produce motion and the geometric and time aspects of motion. Kinetics also explains how a body responds to a force or torque. For example, if the rotational motion is being studied, kinetics would refer to the study of torque that causes the rotational motion.
Kinematics: Studies the position, acceleration, and speed of an object. Kinematics uses equations of motion to describe motion, but does not consider the mass of the object. Kinematics is the description of motion in terms of position, velocity, and acceleration. 

Kinetics and kinematics are two of the main branches of dynamics, which is the study of forces and motion.
