Earlier in Lesson 6, four kinematic equations were introduced and discussed. A useful problem-solving strategy was presented for use with these equations and two examples were given that illustrated the use of the strategy. Then, the application of the kinematic equations and the problem-solving strategy to free-fall motion was discussed and illustrated.
Kinematics problems generally concern the motion of objects and are often solvable using a set of four equations. A typical kinematics problem can involve an object in free-fall, the projectile on a parabolic arc or the motion of a vehicle. The quantities associated to the motion of objects include velocity, time, displacement and acceleration.
In classical mechanics, Kinematics is the study of motion without considering what causes the motion. The key interest in such a study is usually the position and its time derivative i.e velocity and acceleration. For example: A ball is thrown up ...
Kinematics is the branch of mechanics concerned with the motions of objects without being concerned with the forces that cause the motion. In this latter respect it differs from dynamics, which is concerned with the forces that affect motion. There are three basic concepts in kinematics - speed, velocity and acceleration.
In this manner, the kinematic equations provide a useful means of predicting information about an object's motion if other information is known. For example, if the acceleration value and the initial and final velocity values of a skidding car is known, then the displacement of the car and the time can be predicted using the kinematic equations.
Kinematics is the study of the motion of objects. Kinematics can tell you a lot about motion, but not everything. In this lesson, we will examine the types of questions kinematics can and cannot ...
A formal study of physics begins with kinematics. The word “kinematics” comes from a Greek word “kinesis” meaning motion, and is related to other English words such as “cinema” (movies) and “kinesiology” (the study of human motion). Kinematic analysis is the process of measuring the kinematic quantities used to describe motion.
Kinematics is the study of the motion of objects without consideration for the forces responsible for that motion. It is a branch of classical mechanics. As a field of study it is very useful as a means for breaking down the motion of an object into its components, such as translational and rotational motion.
Kinematic equations help solve for an unknown in a problem when an object has either a constant velocity or constant acceleration. This video will help you choose which kinematic equations you should use, given the type of problem you're working through.
