Speed and velocity share many similarities, speed is a scalar property while velocity is a vector property. A vector is a scalar quantity with a direction attached to it. More »

The instantaneous velocity in calculus is the first derivative of a function that expresses distance as a function of time. The instantaneous velocity is also depicted graphically as the slope of the tangent line at a sp... More »

The rate of change in velocity is called acceleration. In the study of mechanics, acceleration is computed as it relates to time with a final unit of distance over time squared. More »

Speed measures how fast an object is moving, whereas acceleration is how much the speed of an object changes during a specified period of time. If an object is speeding up, it has a positive acceleration, whereas an obje... More »

Speed and velocity are similar in that they are measured in the same measurement units, which are meters per second. However, velocity and speed are very different quantities because one has a direction and the other one... More »

Resultant velocity is the vector sum of all given individual velocities. Velocity is a vector because it has both speed and direction. There are many ways to calculate vector sums, such as using a vector addition diagram... More »

The general formula for finding speed is x = d / t, where "x" denotes the speed, "d" indicates the distance traveled and "t" represents the time it takes to cover "d." Speed is a scalar quantity that is entirely defined ... More »
