Question

1. the formula for acceleration is (change in position)/(change in time) (change in velocity)/(change in time) time squared (change in position)+(change in time)

Explanation:

Acceleration is defined as the rate of change of velocity. The formula for acceleration is \(a=\frac{\Delta v}{\Delta t}\), where \(\Delta v\) is the change in velocity and \(\Delta t\) is the change in time. The option \((\text{CHANGE IN VELOCITY})/(\text{CHANGE IN TIME})\) correctly represents this definition. The other options: \((\text{CHANGE IN POSITION})/(\text{CHANGE IN TIME})\) is the formula for velocity, \(TIME\ SQUARED\) is not a formula for acceleration, and \((\text{CHANGE IN POSITION})+(\text{CHANGE IN TIME})\) is a meaningless combination for acceleration.

Answer:

(CHANGE IN VELOCITY) / (CHANGE IN TIME)
