An object moves 2.5 m. this is an example of a question 3 options: direction distance velocity speed

An object moves 2.5 m. This is an example of a distance

Option B

Explanation:

In the above example, the direction of the object in which it moved is not given here. Hence Option A is invalid. Velocity and speed are similar as they indicate the distance travelled by the object with respect to time.

The distance travelled by the object with respect to time is not given in the example and so Option C and  D are invalid. So distance is the best option.

b.

explanation:

the bal will not change its velocity.
