Questions and Answers

What does acceleration specify?

How rapidly the speed of an object is changing

How rapidly the position of an object is changing

How rapidly the time of an object is changing

How rapidly the velocity of an object is changing (correct)

Is acceleration a vector quantity?

No, because it does not have direction

Yes, because it has magnitude only

Yes, because it has magnitude and direction (correct)

No, because it has neither magnitude nor direction

How is average acceleration defined?

Change in time divided by the velocity

Change in speed divided by the time taken

Change in velocity divided by the time taken (correct)

Change in position divided by the time taken

How can instantaneous acceleration be defined?

<p>As the average acceleration over an infinitesimally short time interval at a given instant</p> Signup and view all the answers

Study Notes

Acceleration

Specifies the rate of change of velocity of an object
A vector quantity, having both magnitude (amount of movement) and direction
Measured in units of distance per unit time squared (e.g., m/s²)

Average Acceleration

Defined as the change in velocity over a time interval, divided by the time interval
Calculated using the formula: Δv / Δt, where Δv is the change in velocity and Δt is the time interval

Instantaneous Acceleration

Defined as the limit of the average acceleration as the time interval approaches zero
Represents the acceleration of an object at a specific instant in time
