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 »

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 »

Velocity is a vector since it is composed of a quantity of speed and a direction. Velocity is defined as the rate at which an object's position changes. More »

An object does not have a varying speed if its velocity is constant. A constant velocity implies that an object is moving in a straight line at an identical rate over time. More »
