Tysm for this vid man i needed this
Very nice example!
Negative velocity and positive acceleration = slowing down
Nice video.
Sir can you please tell me which software you use to teach Thanks in advance

sad that you never got to know :(
Yeah
Error, I think, at 3:52: If acceleration is negative, then speed can't increase, because negative accelaration is slowing down, accel > 0, then speed increase; if accel. = 0, then no speed change; if accel. and sign of velocity doesn't matter. Am I wrong ?

According to my high school textbook: Acceleration can be positive or negative, according to which direction it is in. If the acceleration is to the right, it is positive. If acceleration is to the left, it is negative. If the acceleration is in the same direction as the velocity, the particle is speeding up (accelerating). If the acceleration is in the opposite direction from the velocity, the particle is slowing down (decelerating). If the object is traveling at a constant velocity, there is no acceleration. i.e. a=0 So i think if u just remember velocity and acceleration as rates of change, it seems easier to understand

Останин Вадим thanks so much for asking this question!! it was exactly what i needed to be answered, i thought the exact same thing

when accel and velocity are opposite signs the object is slowing down
