Question

question 1 4 pts enter the correct signs of acceleration into this table. speeding up slowing down positive direction select select negative direction select select +a 0 -a

Explanation:

Step1: Recall acceleration - velocity relationship

Acceleration has the same sign as velocity when speeding up.

Step2: Determine signs for positive - direction cases

When moving in positive direction and speeding up, acceleration is positive (+a). When moving in positive direction and slowing down, acceleration is negative (-a).

Step3: Determine signs for negative - direction cases

When moving in negative direction and speeding up, acceleration is negative (-a). When moving in negative direction and slowing down, acceleration is positive (+a).

Answer:

Positive Direction, Speeding Up: +a
Positive Direction, Slowing Down: -a
Negative Direction, Speeding Up: -a
Negative Direction, Slowing Down: +a
