Question

Determine for each of the following statements whether it is correct or incorrect.

- An object can have a zero velocity and still be accelerating.

-The velocity of an object can reverse direction when its acceleration is constant.

-If the acceleration of a body is constant as measured from a given reference frame, it is necessarily constant when measured from all other reference frames.

-When the velocity is constant, the average velocity over any time interval cannot differ from the instantaneous velocity at that instant .

-An object with a constant speed cannot accelerate

Explanation / Answer

An object can have a zero velocity and still be accelerating. (Incorrect)

The velocity of an object can reverse direction when its acceleration is constant. (Incorrect)

If the acceleration of a body is constant as measured from a given reference frame, it is necessarily constant when measured from all other reference frames. (Incorrect)

When the velocity is constant, the average velocity over any time interval cannot differ from the instantaneous velocity at that instant . (Correct)

An object with a constant speed cannot accelerate (Correct)
