Questions and Answers
What does acceleration specify?
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?
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?
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

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
