Question: An object covered a certain distance in a given period of time. which of the following quantity is used to describe the object’s motion?
One possible quantity that can be used to describe the object’s motion is speed. Speed is defined as the ratio of distance traveled to time taken. Speed tells us how fast or slow an object is moving, but it does not tell us the direction of the motion. Another possible quantity that can be used to describe the object’s motion is velocity. Velocity is similar to speed, but it also includes the direction of the motion. Velocity tells us how fast and in what direction an object is moving. A third possible quantity that can be used to describe the object’s motion is acceleration. Acceleration is defined as the rate of change of velocity over time. Acceleration tells us how quickly an object is speeding up, slowing down, or changing direction.
