Question

Which vector should be negative?

any vector whose magnitude is less than 1


a displacement in the direction North


any vector whose magnitude is greater than 1


the velocity of a falling object

Answer 1

Answer: the velocity of a falling object.

As the object is falling down it is experiencing a velocity that is continuously reducing each second and becomes 0 once it reaches the ground. The graph between velocity and time in this case would be a negative slope.

Thus for a object falling down the velocity considered would be negative owing to the reducing speed.
