' 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.
What describes both speed and direction?
Velocity describes both speed and direction. Speed is the magnitude of velocity, while direction indicates the path of an object's motion.
What is a measure of both speed and direction of an object?
Velocity is a measure of both speed and direction of an object. It indicates the rate at which an object changes its position in a particular direction over time.
Which includes both speed and direction?
Velocity is a vector quantity that includes both speed and direction. Speed is the magnitude of velocity, while direction indicates its movement in a specific path or orientation in space.
What is the speed of an object but in a specific drection?
The speed of an object in a specific direction is referred to as velocity. It is a vector quantity that includes both the speed and direction of motion. Velocity indicates how fast an object is moving and in which direction.
The what of an object consists of its speed and direction?
The velocity of an object consists of its speed and direction. Speed refers to how fast an object is moving, while direction indicates the path that the object is following. Velocity is a vector quantity as it has both magnitude (speed) and direction.
What measures speed and direction an object travels?
Velocity measures both speed and direction that an object travels. The magnitude of velocity represents the speed of the object, while the direction of velocity indicates the direction in which the object is moving.
What do you need to know to describe a velocity?
To describe velocity, you need to know both the speed of an object and its direction of travel. Velocity is a vector quantity that includes both magnitude (speed) and direction, so specifying both is essential. It is typically denoted with a velocity vector, which indicates the speed and direction an object is moving.
Does velocity describes the speed and direction of an object?
Yes, velocity describes both the speed and direction of an object's motion. Speed is the magnitude of velocity (how fast the object is moving), while direction indicates the path the object is following.
What is the name of the speed with direction?
Velocity is the measurement of the rate and direction of change in the position of an object. It is a vector quantity; both magnitude and direction are required to define it. The scalar value of velocity is speed. For example, a speed of "5 meters per second" is a scalar and not a vector measurement, whereas a velocity of "5 meters per second east" is a vector measurement stating both speed and direction.
Why can velocity be negative but nonzero speed is always positive?
Velocity includes both speed and direction, so a negative velocity indicates motion in the opposite direction. Speed, on the other hand, is a scalar quantity representing the magnitude of velocity without regard to direction, and therefore is always positive.
What describes how an object is moving and how fast?
The object's motion is described by its velocity, which includes both speed and direction. The speed tells us how fast the object is moving, while the direction indicates the path it is following.
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.
