What is kinematics and dynamics?
How can you explain this briefly and simply to someone who knows nothing about it?
Hello, a transformer must have different numbers of turns. But why? If I have 159 turns in n1 and 50 in the other, what happens in between? Where does the voltage go to reduce it?
Hi. I tried a physics problem for fun and I'm not entirely sure if I solved it correctly. Here is the task: In one scientific study, a peregrine falcon flying at an altitude of 372 m accelerated from 40 km/h to strike a pigeon at a height of 38 m above the ground after 16…
can someone help me please? I = Io * e^-µ*d I = 10000 * e^-3/cm* 20cm = 8.756 * 10^-23 is that right?
An electric kettle has a current of 9 A at a voltage of 230 V. It is used for 20 minutes a day. How many kWh of electrical energy does that produce in 30 days?
A closed system simply describes a system in which no exchange of substances takes place, but energy exchange does. In the case of a closed/isolated system, I would understand the statement mentioned in the question, since no energy exchange takes place there. But in a closed system, heat, for example, can be released back into…
I don't understand the debate about whether complex quantities in quantum physics influence reality or play a role in it, since electrical engineers have been using reactive current in AC circuits for years, as the resulting reactive load puts a strain on electrical components. Is there a way to untangle my confusion?
kinematics is concerned with movement. The physical variables are mainly used in location, speed, acceleration and time. I.e. questions could be: “How far does an object come when it has been accelerated for a certain time with a certain acceleration?” or “How fast does something have to be to arrive in a place at a certain time?”
Dynamics deals with the cause, effect and transmission of forces. For example, the Newton’s axioms are introduced here, which make a very accurate statement about how forces affect matter. Often, a force leads to an acceleration, which quickly leads to kinematics, but within the dynamics it is more about what forces have to do with it. Energy and impulse also belong to this subarea, since they are generally very closely related to forces.
Kinematics and dynamics are two branches of classical mechanics that deal with the movement of objects. Kinematics is the study of movement without taking into account the forces that cause movement, while dynamics is the study of movement and forces that cause it. The kinematics deals with the position, speed and acceleration of objects, while the dynamics deal with the forces and torques that cause the movement.
