The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
Average acceleration points in the same direction as the change in velocity over time. If the velocity is increasing, the average acceleration will be in the same direction as the velocity. If the velocity is decreasing, the average acceleration will be in the opposite direction.
A negative average velocity indicates that an object is moving in the opposite direction of the chosen positive direction. For example, a negative average velocity would mean the object is moving left if the positive direction is considered right.
No, distance and average velocity are not the same. Distance is the total amount covered by an object irrespective of direction, while average velocity is the displacement of an object divided by the time taken, taking direction into account.
A quantity that has a direction associated with it is called a vector. Vectors are used to represent physical quantities that have both magnitude and direction, such as force, velocity, and displacement.
The total displacement divided by the time. The slope of the displacement vs. time graph.
Velocity is speed and its direction. Average velocity is average speed and its direction.
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
Average acceleration points in the same direction as the change in velocity over time. If the velocity is increasing, the average acceleration will be in the same direction as the velocity. If the velocity is decreasing, the average acceleration will be in the opposite direction.
A negative average velocity indicates that an object is moving in the opposite direction of the chosen positive direction. For example, a negative average velocity would mean the object is moving left if the positive direction is considered right.
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
Speed is the rate at which something moves, and can be calculated by the equation: speed = distance / time. Speed does not have a direction associated with it. So if you are in a car and travel 60 miles in 2 hours, your average speed would be 30 miles per hour. Velocity is very similar to speed, but it does have a direction associated with it. That is the only difference.
No, distance and average velocity are not the same. Distance is the total amount covered by an object irrespective of direction, while average velocity is the displacement of an object divided by the time taken, taking direction into account.
The speed of something in a given direction.
A quantity that has a direction associated with it is called a vector. Vectors are used to represent physical quantities that have both magnitude and direction, such as force, velocity, and displacement.
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
The total displacement divided by the time. The slope of the displacement vs. time graph.
