Velocity is a vector quantity that measures speed with s specific direction or displacement/time.
And speed is a scalar quantity that measures how fast an object moves which is distance/time.
Speed only has magnitude and velocity includes direction like 65 mph North.
Also speed is always positive, and velocity can be zero or even negative.
Speed is a scalar or scalar quantity because speed describes only how fast the object is moving "magnitude" without specifying any direction.
So unlike velocity, which is a vector which requires magnitude and direction, the speed only solely represents the rate at which the object covers distances.
Speed is a scalar, which means that speed has magnitude but no direction.
A scalar is a quantity that is described only by magnitude such as a number and unit with no direction, like speed, mass or temperature.
And velocity is a vector quantity that represents the rate of change of an objects position or displacement over time, which requires both direction and magnitude also known as speed, like 60 mph North.
The reason why velocity is not a scalar quantity is because velocity requires both direction and magnitude or speed to be fully defined, which makes velocity a vector quantity.
And a scalar only indicates how fast something is moving, and velocity defines how fast and also in what direction an object moves, such as 50 mph north, which makes direction essential in velocity.
The velocity is the speed of an object in a specific direction.
Speed tells you how fast something is moving like a car moving at 65 mph down highway, and velocity includes the direction like 65 mph west, which makes it a vector quantity.
Velocity measures how quickly an object changes it's position in a particular direction.
The three types of velocity are constant (uniform) velocity, variable (non-uniform) velocity, and instantaneous velocity.
These types of velocities describe how the speed of an object and it's direction change over time or at specific moments, which is distinct from average velocity, which calculates total displacement over a total time interval.
Uniform constant velocity is when an object moves in a straight line at a constant speed, which means both magnitude and direction remain unchanged.
Variable non uniform velocity is when an object's speed, direction or both change over time, like a car accelerating, decelerating or turning.
Instantaneous velocity is the velocity of an object at a precise, specific point in time.
Other types of velocity are terminal velocity, which is maximum velocity reached by a falling object and average velocity which is total displacement divided by total time.
Velocity can slow down because velocity changes whenever an object speeds up or slows down or changes direction, which is a process called and known as acceleration.
An object slows down or decreases in it's speed when it's acceleration acts in the opposite direction of it's velocity and is often referred to as deceleration or negative acceleration.
Velocity can be negative as velocity is a vector quantity and both magnitude and direction and a negative velocity indicates that an object is moving in the opposite direction of what has been defined as the positive direction, like for example moving left, down or backward.
If right is positive, then -5 m/s means moving to the left at 5 m/s.
Velocity is sometimes zero, which indicates that the object is momentarily at rest or stationary relative to a frame of reference.
When in object is thrown upwards, the velocity of the object become exactly zero at it's highest point, even though the gravity "acceleration" is still acting upon it.
And if an object reverses it's direction, it's velocity also must pass through zero.
Velocity is also relative, so an object can also have zero velocity in one frame of reference while moving in another.
An object's average velocity can also be zero like for example, driving around a track and returning to the start even if it's instantaneous velocity was rarely zero.
Velocity is the rate that an object changes it's position in a specific direction, combining both speed as well as direction.
And unlike just speed "how fast", velocity is a vector quantity, which means that velocity includes magnitude and direction like for example, 60 km/h North.
Velocity is calculated as displacement divided by time.
Velocity requires both speed (magnitude) and direction.
The difference from speed and velocity is that speed is a scalar like (50 mph) for example and velocity is a vector like (50 mph East).
An object can also have speed but also have 0 velocity.
If the object returns to it's starting point then the displacement is zero.
Velocity is also commonly measured in meters per second or (m/s) in the SI system, or kilometers per hour (km/h), miles per hour or (mph).
Velocity is also used in physics to calculate momentum like for example momentum = mass X velocity and in engineering to determine motion.
When you're driving, your vehicle's speedometer is showing your speed, but your GPS navigation system is showing your velocity by factoring in your direction.
Simply put, velocity is how fast something is moving and the direction it's going, like a car going 60 miles per hour north, while speed is just how fast, like 60 miles per hour.
You can think of velocity as speed with a compass direction (north, south, east, west, or up/down) attached, making it a "direction-aware" measurement of motion.
For example for speed, a skateboarder would be going 5 miles per hour or mph.
And for the velocity of the skateboarder the skateboarder would be going 5 mph down the hill.
