Question

In order to describe the velocity of an object, which three pieces of data are needed?

� The mass of the object in grams � The speed at which the object traveled � The pull of gravity on the object

� The distance traveled by the object � The time taken to travel � The direction of travel

� The mass of the object in grams � The time taken to travel � The acceleration of the object object

� The distance traveled by the object � The force the object had on another object � The mass of the object in grams

Answer 1

To describe an object's velocity, one needs the object's speed, direction of travel, and distance traveled or displacement.

Step-by-step explanation:

To describe the velocity of an object, three pieces of data are necessary: (1) the speed at which the object traveled, which tells us how fast the object is moving, (2) the direction of travel, which establishes the orientation of the motion, and (3) the distance traveled by the object or its displacement, which informs us about the change of location over a certain period. Therefore, the required information to describe velocity is not about the object's mass, the pull of gravity, or forces exerted on other objects, but rather about its speed, direction, and distance or displacement over a period of time.
