Machine Kinematics Practice Test: Kinematics & Kinetics of Motion
Fast practice, instant feedback. Timer auto-submits when time’s up.
Avg score: 50% Most missed: “A car starts from rest and accelerates uniformly to a speed of 72 km. p.h. over …”
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... Show more
