And object's speed refers to a magnitude of movement in relation to something (often the ground or a stationary relative object). A Vector, usually represented by an arrow, shows a scalar (some magnitude or speed) and a direction. The scalar magnitude could be an object's speed. However, without a directional component, it's not a vector, simply a speed of scalar. Velocity IS a vector because velocity by definition includes a scalar (force/speed) AND a direction in which it is moving. Therefore Velocity is a Vector, but Speed is only part of what makes a Vector.
Example: Bob is running 10 mph North along a sidewalk. His velocity is 10 miles per hour North. A Vector drawing would show an arrow 10 units long pointing North along the sidewalk. It's speed is a flat 10 mph at that given moment, it is the scalar portion of the vector without the directional component.
As an addition, Acceleration is the rate of change in Velocity. So we have a Speed- 10 mph. Then we have Velocity- 10 mph North. Acceleration is what shows his velocity changing...
How quickly does he speed up at the beginning of his run...
How quickly does he slow down at the end...
At what rate does his direction/speed change as he turns a corner...etc.
What else can I help you with?
Is constant speed constant velocity?
No. Velocity includes a direction vector, which speed does not have.
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
What Has Direction Speed or Velocity?
Velocity has direction. Speed is a scalar quantity that only measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
Why achanging velocity cannot maintaining constant speed?
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.
Explain the difference between velocity and speed?
Velocity includes both speed (magnitude of the velocity) and direction, while speed is just the magnitude of the velocity without any indication of direction. So velocity is a vector quantity, whereas speed is a scalar quantity.
What is the distance than an object travels ina given time?
speed or velocity = distance/time Speed does not require direction, i.e. it is a scalar quantity. Velocity does require direction, i.e. it is a vector quantity.
What quantity gives both the speed and the direction of an object?
Velocity represents a quantity that combines speed (magnitude) and direction for an object in motion. It is a vector quantity that includes both a numerical value for the speed and information about the direction of motion.
Why do we say that velocity is a vector and speed is not a vector?
Velocity is a vector because it has both magnitude (speed) and direction. Speed, on the other hand, is a scalar quantity that only has magnitude. Vector quantities require both magnitude and direction to be fully described.
What is speed in a given direction is called?
Speed in a given direction is velocity.
You are snowboarding at Marmot Basin and you travel 600 m in 30 seconds What is your velocity?
20 meters per second is the speed--velocity would require direction data, as well. Velocity is a vectored quantity.
Are speed and velocity different?
SPEED has the speed only; while VELOCITY has the direction and the speed.
How is speed of a body related its velocity?
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
What is speed in a given direction?
Speed in a given direction is called velocity.
How do you find speed if you know the velocity?
Velocity is speed and direction
What is the difference betweenn speed and velocity?
Velocity is speed with a direction
What is instantaneous velocity or speed?
It is the speed or velocity at a particular instant.
How are speed and velocity diffrent?
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
