Acceleration is _______________.(1 point)
Responses
a An object’s speed when its motion is constant
b An object’s velocity’s rate of change
c An object’s speed in a specific direction
d An object’s direction’s rate of change
b An object’s velocity’s rate of change
To determine the correct answer for the definition of acceleration, we need to understand the concepts involved.
Acceleration is a measure of how an object's velocity (speed in a specific direction) changes over time. It specifically refers to the rate of change of velocity. Therefore, the correct answer would be:
b) An object’s velocity’s rate of change
To elaborate, acceleration can be calculated using the formula:
acceleration = change in velocity / time
This formula tells us that acceleration is the ratio of the change in an object's velocity to the time it takes for that change to occur. A positive acceleration means the velocity is increasing, a negative acceleration means the velocity is decreasing, and zero acceleration means the velocity is constant.
