Speed vs Velocity

Speed is the rate at which an object covers distance, while velocity is a vector quantity that includes both magnitude and direction.

The SI unit for both speed and velocity is meters per second.

The average speed of an object is calculated by dividing the total distance traveled by the total time taken. The equation for average speed is: $Average\ speed = \frac{Total\ distance\ traveled}{Total\ time\ taken}$.

<p>By examining the slope of the line on a position-time graph, we can determine the object's velocity. A constant slope indicates a constant velocity, while a changing slope indicates a changing velocity.</p> Signup and view all the answers

<p>Average velocity is calculated by finding the slope of a line connecting two points in time on a position-time graph. Instantaneous velocity, on the other hand, is the velocity at a specific point in time and is found by finding the slope of the tangent line at that point.</p> Signup and view all the answers

<p>The magnitude and direction of velocity, both average and instantaneous, can be deduced by looking at the slope of a line on a position-time graph. Positive slopes indicate motion in the positive direction, away from the origin, while negative slopes indicate motion in the negative direction, back toward the origin.</p> Signup and view all the answers

<p>Speed is a scalar quantity that represents the rate at which an object covers distance. It only has magnitude and does not consider direction. Velocity, on the other hand, is a vector quantity that includes both magnitude and direction. It describes the rate at which an object changes its position in a specific direction.</p> Signup and view all the answers
