Question

Which of the following best describes the difference between speed and acceleration?

A.
Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.

B.
Acceleration is the distance an object travels within a specific unit of time, whereas speed is the rate at which the acceleration or direction of an object is changing.

C.
Speed is the distance an object travels within a specific unit of time, whereas acceleration is a measure of the force necessary to change the speed of an object.

D.
Acceleration is the distance an object travels within a specific unit of time

Answer 1

A. Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.

Step-by-step explanation:

Speed is the distance an object travels within a specific unit of time. The average speed of an object can be calculated by dividing distance over time. Acceleration, on the other hand, is the rate at which the speed or direction of an object is changing. Acceleration can be positive or negative.

Answer 2

'A' is a good true statement.

'B', 'C', and 'D'; are just plain false.
