In 28-2 Radiation Feynman starts talking about the third term of Eq. 28.3 and why that it varies with the inverse of the distance. On page 28-4 he says that the unit vector e'r is pointed to the apparent position of the charge. I understand...

In paragraph 11-6 he says that the tangent acceleration is the change of speed v but if I look at fig. 11-8 the change in speed is slightly smaller than the change in tangent velocity. (I drew a circle with the radius of the speed of v_I that...
I understand it mathematically but not physically. It's my first time looking into these collisions. How does this work? Which process turns the uniform motion into other forms of energy? Why is it not dependent on other properties? Why does sticking together leads to KE loss?
Can you elaborate on this? This is kind of too abstract for me.
Does this mean that for these masses and velocity always the same amount of kinetic energy is lost? I'd imagine it would also depend on the materials or contact area etc.
Suppose we have two objects and we're only talking about rectilinear motion.
Initially, one object has mass m and is moving at velocity V. The other has mass M and is standing still.
Then they hit each other and suppose that all kinetic energy is conserved and they stick together and move at...
I'm having a hard time wrapping my head around some of the basic concepts.
Imagine a spaceship moving at a certain velocity relative to you. To you, his time is slower than yours. He guy in the spaceship doesn't know his time is slowed down.
If his time is slower than yours, it means that he...
I'm still in high school. I'm reading about physics as a hobby.
