Question

If the velocity of an object is changing, this must be caused by a(n):

A. Speed
B. Acceleration
C. Distance
D. Time

HELP PLEASEEE

Answer 1

B. Acceleration

Acceleration is defined as a change in velocity, shown by the formula a = Δv / t, or the change in velocity over time. If the velocity is changing, there must be an acceleration.

Answer 2

An acceleration

Step-by-step explanation:

When a velocity changes concerning time, acceleration has a value and comes into play. Acceleration is what causes a velocity to change each time. It can be expressed as:

`\displaystyle{\vec a = (d \vec v)/(dt)}`

Where dv is a minimal change in velocity, and dt is a minimal change in time. There will be no velocity changes if there is no acceleration, meaning it becomes 0.
