to locate an object what do you need to know?
[object Object]
you need to know where the object is and where it is after a period of time
To locate an object, you typically need to know its specific or general location, such as an address or geographical coordinates. Additional information like physical descriptions, names, or unique identifiers of the object can also help in finding it. Utilizing tools like maps, GPS devices, or assistance from others can further aid in the location process.
Not necessarily. Knowing an object's speed and direction of motion does not automatically provide information about its acceleration, which is the rate of change of velocity. Acceleration depends on how much the velocity is changing over time, which might not be evident just from knowing the initial speed and direction.
i need to know this
You might use Newton's Second Law. In this case, you would need to know (a) all forces that act on the object, and (b) the object's mass.
to know the height the width length of an object.
We need to know the shape of the object.
why the hell should i know i need the answer
The mass of the object.
Mass and weight are both capable of telling you how much matter is in an object, it just depends on what other information you have. For instance if you have weight then you will also need to know the gravity and the density of atoms per gram of this object. If you know mass which is different from weight then you will only need to know the density of the object.
