Can someone quickly give me a brief summary of what certain things infer when presented in a question. Im getting kind of confused.

For example,

when the velocity is equal to zero(set v(t) equal to o)

When does the particle reverse direction

More stuff along those lines.


Thanks.

i think the velocity is the first derivative

velocity first derivate, accel 2nd

if v is = 0 and a is not, then it is reversing direction.

there's some more but that's the basics

Yea Thats About Right
