    Physics Velocity
AI Thread Summary
Velocity is a vector quantity that includes both speed and direction. When an object moves with constant speed in a straight line, it is indeed moving with constant velocity. The phrase "moving with constant velocity in a straight line" is technically accurate, but the "straight line" specification is redundant since constant velocity implies no change in direction. Therefore, both statements about speed and velocity are correct. Understanding this distinction is crucial in physics discussions.

Since velocity is a vector, when I say an object is moving with constant speed in a straight line, am I just saying that it is moving with constant velocity?

And if someone says that an object is "moving with constant velocity in a straight line", the straight line part is actually unnecessary.

Is that correct?

Both are correct! :biggrin:
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
