Does speed have a direction
WebJul 7, 2024 · Does speed have direction? Note that speed has no direction (it is a scalar) and the velocity at any instant is simply the speed value with a direction. Why do we use displacement? Displacement is needed to find the final position of an object; it tells not only the distance from the starting position, but also the net direction of travel ... WebWhat does the motion of an object depend on? The reference point that is chosen and the observer's frame of reference. What can motion be described by? Distance, position, displacement, speed, acceleration, and time. What term do you use to describe an object's motion by how far it has moved?
