difference between velocity and speed

Question

Answer

velocity is a vector quantity Speed is a scalarspeed give information about distance per unit timevelocity Say's about displasement per unit time

Answer

speed is distance travelled per unit time ,vilocity is also distance travelled per unit time, but difference is speed is scaler quantity and vilocity is vector quantity.

Answer

speed has only magnitude and velocity has both direction and magnitude

Answer

SPEED is a scalar quantity whereas VELOCITY is a vector quantity.
SPEED has no direction whereas VELOCITY has direction.
SPEED is the rate of change of motion whereas VELOCITY is the rate of change of displacement.

Answer

displacement per unit time is called velocitydistance per unit time is called speed velocity is a vector quantity that has both magnitude and distancewhile speed is a scalar quantity having magnitude only not distancevelocity may be zero while speed can never be zero

Answer

Speed is distance travelled per unit time , it is scalar quantity. Whereas velocity is distance travelled per unit time in given direction,it is vector quantity

Answer

Velocity vs Speed: Understanding the Difference

Velocity and speed are two fundamental concepts in physics that describe the motion of an object. While they are often used interchangeably in everyday language, they have distinct meanings in the world of physics. Let's delve into the differences between velocity and speed.

Speed:
Speed is a scalar quantity that represents how fast an object is moving. It is defined as the rate at which an object covers distance. Speed is a straightforward concept and is measured in units such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph). The formula to calculate speed is:

Speed = Distance / Time

Some key points about speed include:

1. Scalar Quantity: Speed is a scalar quantity, which means it only has magnitude and does not have a specific direction associated with it. For example, if a car is traveling at a speed of 60 km/h, it tells us how fast the car is moving but not in which direction.

2. Constant or Average: Speed can be either constant or average. Constant speed refers to an object moving at the same speed throughout its journey, while average speed is calculated by dividing the total distance traveled by the total time taken.

Velocity:
Velocity, on the other hand, is a vector quantity that represents both the speed and direction of an object's motion. It describes how fast an object is moving in a specific direction. Velocity is also measured in units like meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph). The formula to calculate velocity is:

Velocity = Displacement / Time

Here are some important distinctions about velocity:

1. Vector Quantity: Unlike speed, velocity is a vector quantity as it includes both magnitude (speed) and direction. For instance, if a car is traveling at a velocity of 60 km/h north, it indicates the car's speed and the fact that it is moving in a northward direction.

2. Change in Position: Velocity takes into account the change in position (displacement) of an object over a specific time interval. Displacement refers to the straight-line distance between an object's initial and final positions, along with its direction.

Summary:
In summary, the key differences between velocity and speed can be summarized as follows:

1. Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity representing both speed and direction.
2. Speed only considers the rate at which distance is covered, while velocity takes into account the displacement of an object.
3. Speed is always positive or zero, whereas velocity can be positive, negative, or zero, depending on the direction of motion.
4. Speed is a straightforward concept, while velocity provides more detailed information about an object's motion.

Understanding the distinction between velocity and speed is crucial in physics as it allows for precise descriptions of an object's motion and helps in analyzing various physical phenomena.
