Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).
What else can I help you with?
What would describe both speed and direction of a moving object?
The speed and direction of an object is its velocity.
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
Which of the following would be a change in velocity but not in speed?
Velocity is a vector quantity, i.e. it consists of two measures, one is speed, the other is direction. If the speed remains constant then a change in direction would alter the velocity. (you didn't list any examples)
Can an object have a varying speed it its velocity is constant?
Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.Yes. Velocity is (speed and direction of motion). If direction changes, then velocitychanges, even if speed is constant.Examples:-- Car going around a curve at a constant speed has changing velocity.-- Anything traveling a circular path at a constant speed has changing velocity.
What do we call a speed at which a wave travels?
The speed at which a wave travels is called its velocity. This velocity is typically determined by the frequency and wavelength of the wave.
How would you differentiate speed time distance and velocity?
Velocity is a vector: it has a direction. The others are all scalars. The dimensions of the scalars are Speed : [LT-1] Time: [T] Distance: [L]
What factor is the difference between speed and velocity?
Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE
What is speed in a given direction is called?
Speed in a given direction is velocity.
What is the speed and velocity triangle formula?
Velocity = Speed / Time So, in the context of a triangle, speed would be at the top.
Is speed a component of scalar?
Yes, velocity would be the vector companion of speed, as velocity must have a direction.
How would you differentiate speed of reaction and timing?

Why we does not use speed instead of velocity?
When the direction of motion is relevant, you would use velocity rather than speed.
What would have to be true for the velocity to be constant?
the speed would have to change.
What would describe both speed and direction of a moving object?
The speed and direction of an object is its velocity.
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
Which of the following would be a change in velocity but not in speed?
Velocity is a vector quantity, i.e. it consists of two measures, one is speed, the other is direction. If the speed remains constant then a change in direction would alter the velocity. (you didn't list any examples)
What is an objects velocity?
An object's velocity is it's speed plus direction. example: 55mph south Hope this helps:)
