Difference between statics, dynamics, kinematics and kinetics

Click For Summary
Statics refers to the study of forces in systems at rest, where speed is zero. Dynamics involves the analysis of forces and motion when speed is changing, indicating acceleration. Kinematics focuses on the description of motion without considering the forces, while kinetics examines the relationship between motion and the forces causing it. Both kinematics and kinetics can involve constant speed, but kinematics also includes accelerated motion. Understanding these distinctions is crucial for grasping the fundamentals of physics mechanics.

Dear All,

I am often get confused when four terms STATICS,DYNAMICS,KINEMATICS and KINETICS are used in physics Mechanics.can someone please differentiate between these four terms.i will be thankful.
 
Physics news on Phys.org
Statics : speed is zero
Kinematics and kinetics : speed is constant
Dynamics : speed is changing (there is acceleration)
 
Kinematics studies accelerated motion as well.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
