Velocity of a moving body is its rate of DISPLACEMENT with respect to time.
But speed is distance traveled per unit time.
The difference between speed and velocity is that velocity has a direction.
30mph is a speed.
30mph due north is a velocity. Well not really because 'north' is arbitrary but you get the idea.
Displacement is both a distance and direction.
30 miles is a distance.
30 miles to the north is a displacement.
A two part quantity like velocity or displacement is called a 'vector quantity'. A one part quantity (speed, distance etc) is called a 'scalar quantity'.
What else can I help you with?
Can speed change the velocity of an object?
Speed is measured in m/s. Velocity is measured in m/s IN A SPECIFIC DIRECTION. You may be driving at 4 mph north, or at 5 mph at 330˚, and your velocity in the northern direction will still be 4 mph. In this example, your speed is different, but your velocity is the same. Thus even if speed remains constant, but its direction changes, your velocity will be different.
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
How are velocity and acceleration different?
Velocity is the rate of change of position of an object with respect to time, while acceleration is the rate of change of velocity of an object with respect to time. Velocity describes how fast an object is moving and in which direction, while acceleration describes how quickly the velocity of an object is changing, either in speed or direction.
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
What is the speed of an object plus its direction?
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
Can speed change the velocity of an object?
Speed is measured in m/s. Velocity is measured in m/s IN A SPECIFIC DIRECTION. You may be driving at 4 mph north, or at 5 mph at 330˚, and your velocity in the northern direction will still be 4 mph. In this example, your speed is different, but your velocity is the same. Thus even if speed remains constant, but its direction changes, your velocity will be different.

What it isn't velocity?
Velocity is often confused with speed, but it is fundamentally different. While speed refers to how fast an object is moving, velocity includes both speed and direction. This means that two objects can have the same speed but different velocities if they are moving in different directions. Additionally, if an object returns to its starting point, its velocity can be zero, even if it has traveled a considerable distance.
What describes the direction and speed of an object?
Velocity describes the speed and direction of an object.velocityvelocity

What is the speed of an object plus its direction?
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
What is the specific direction of a speed of an object?
The specific direction of an object's speed is known as velocity. Velocity includes both the speed of the object and the direction in which it is moving.
What two factors indicate the velocity of an object in motion?
The magnitude and direction of an object's velocity indicate the speed and movement of the object. The magnitude represents the speed of the object, while the direction depicts the object's movement in space.
What is the difference between an object's speed and a object's velocity?
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
What measures speed and direction an object travels?
Velocity measures both speed and direction that an object travels. The magnitude of velocity represents the speed of the object, while the direction of velocity indicates the direction in which the object is moving.
