To calculate the position from velocity or speed alone, you need to know the initial position or a reference point. If you have the initial position and the velocity or speed, you can use the following formulas:
If you have the velocity (a vector quantity, which includes both magnitude and direction): position = initial position + velocity * time
This formula assumes that the velocity remains constant over the given time period.
If you have only the speed (a scalar quantity, which represents magnitude but not direction): position = initial position + speed * time
Here, the direction of motion is not explicitly considered because speed does not provide direction information. This formula assumes constant speed in a straight line.
In both cases, "time" represents the elapsed time from the initial position to the desired position.
It's important to note that these formulas provide the position relative to the initial position or reference point. If you need to calculate the absolute position in a coordinate system, you would need additional information, such as the coordinates of the initial position or reference point.
