CAn an object be increasing its speed with negative accelerationexplain why or why not
give an example of when both velocity and acceleration are neg.
can the magnitude of a vector ever equal or be less than one of its components?
If you are riding a train that speeds past another in the same direction on an adjacent track, it appears that the slower moving train is moving backwards. EXPLAIN WHY?
Can the vector of a magnitude have a non zero component?
I have a test tomorrowand need to make sure I can understand the conceptual stuffI have a little bit of a sense on what the answers to these questions might bebut Im not suresome guidance would help
THANKS

if an object's velocity is in the same direction as it's acceleration then the speed is increasingex: dropping a ball,negative velocity n negative acceleration so speed increases
opposite direction then object will slow
ex: throwing ball upward velocity is positive but acceleraion is negative due to gravity =9.81m/s^2
vector magnitude can be = but not less than it's componet ex: straight line has y component of 0 but the mag of vector is = to the x component
