What are the differences between velocity and speed?

Question

Answer

velocity depends on displacement and speed depends on distance

Answer

Speed:the distance travelled by a body in unit time is known as speed.Velocity:the displacement travelled by a body in unit time is known as velocity.

Answer

Speed: it is scaler quantity, it is always positive, average speed of body can be zero.Velocity: it is vector quantity, it can be positive negative or zero, it tells us that how fast an object is moving in a particular direction.

Answer

1.distance travelled per unit time is called speed displacement covered per unit time is called velocity2.speed is a scalar quantity having magnitude only no directionvelocity is a vector quantity having both magnitude and direction3.speed can not be zero but velocity of an object may be zero

Answer

Velocity vs. Speed:

Definition:
- Velocity: Velocity is a vector quantity that measures the rate at which an object changes its position. It includes both the speed and direction of an object's motion.
- Speed: Speed is a scalar quantity that measures how fast an object is moving. It only considers the magnitude of the motion, not the direction.

Direction:
- Velocity: Velocity includes direction, so two objects can have the same speed but different velocities if they are moving in different directions.
- Speed: Speed does not consider direction, so two objects moving in different directions but at the same speed will have the same speed value.

Units:
- Velocity: The SI unit for velocity is meters per second (m/s) and is often represented by a vector with both magnitude and direction.
- Speed: The SI unit for speed is also meters per second (m/s) but is represented by a scalar value without direction.

Mathematical Representation:
- Velocity: Velocity is represented as a vector quantity with both magnitude and direction, often denoted as v = Δs/Δt, where Δs is the displacement and Δt is the time taken.
- Speed: Speed is represented as a scalar value, denoted as v = d/t, where d is the distance traveled and t is the time taken.

Conclusion:
Velocity and speed both measure how fast an object is moving, but velocity also includes the direction of motion. Understanding the differences between velocity and speed is crucial in physics and other scientific fields to accurately describe and analyze the motion of objects.

Answer

thank you

Answer

velocity is a vector quantity   and is a scalar quantity

Answer

velocity :::::::::: 1.It is rate of change of speed .2.it's SI unit is m/s and  can be negative 3.It is a vector  quantity. but in speed.::::::::::1.it is distance travelled by body per unit time2.it is a scalar quantity 3.its SI unit is m/s and is always positive  (^_^)

Answer

The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc..
