' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
What is 20 miles per hour north an example of?
A velocity vector includes both speed and direction.
Can a body have a uniform speed having an acceleration?
Yes a body can have both a uniform speed and an acceleration. This is because speed is a scalar quantity, meaning it does not depend on direction. Acceleration is a vector quantity, meaning it does depend on direction. This means that when you are changing direction you are accelerating in that direction. During this time your speed may remain constant. Think about taking a turn in a car. You can put on enough gas to keep you at 20 mph but you are still changing direction so you are accelerating.
What do you mean by vectare Quantity give example?
A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).
20 miles per hour north is an example of?
This measure is an example of velocity, which includes both a speed and a direction.
How does velocity differ from speed?
Velocity indicates direction in addition to speed.
A line that indicates both magnitude and direction?
Any "scalar" quantity, such as speed, temperature, frequency, cost, etc.
Can a body have zero velocity and still acceleration?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
Does a car has speedometer velocity are both?
A car has a speedometer. When you read the speed that it indicates, and you know the direction in which you're driving, then you know the car's velocity.
Does velocity depends on both speed and direction?
Yes. Velocity depends on both speed and direction.
How is an anemometer different from a windsock?
An anemometer indicates wind speed, a wind sock, primarily, indicates wind direction
Velocity describes both?
speed and direction
Can a particle with constant speed be accelerating what if it has constant velocity?
Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.
What is acceleration since it has magnitude and direction?
Acceleration is a vector quantity because it has both magnitude and direction.
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
What describes both speed and direction?
Velocity describes both the speed and direction an object is moving.
Velocity differs from speed in that velocity indicates?
Velocity is a vector quantity, which means that a body's speed and direction are both required to define it. They are different because: Speed is the rate of change of distance with time but velocity is the rate of change of displacement with time.
