A vector is represented by an arrow What is the significance of the length of the arrow?
The length of the arrow signifies the magnitude or size of the vector.
How can you use a graph to show acceleration?
With great difficulty. Acceleration is a vector and that means that it has a direction as well as a magnitude (size). For motion in a plane, the only effective way to show acceleration is to draw lots of arrows from points at regular intervals in a plane such that the length of the arrow is a measure of the magnitude of the acceleration and the direction of the arrow coincides with that of the acceleration. An answer referring to a speed-time graph is totally incorrect. That measures speed in the radial direction only. All apects of motion (displacement, speed, acceleration) in a transsverse direction are completely ignored.
Can a vector be represented by an arrow only?
Yes, but only if the size (length) of the arrow is related to some scale.
What is the term for the ratio representing the size of an illustration or reproduction in relation to the object it represents?
The term is "scale."
A direction a vector is drawn indicates the magnitude of the vector?
No. The size of the size of the vector drawn indicates the magnitude.
How vector has both magnitude and direction?
A vector is a mathematical quantity that has both magnitude (size or length) and direction. It is typically represented as an arrow pointing in a particular direction with a specific length representing the magnitude. This allows vectors to be used to describe quantities such as velocity, force, and displacement in physics and other fields.
A vector is a quantity that has?
A vector is a quantity that has magnitude and direction. It is typically represented by an arrow pointing in a specific direction, with the length of the arrow representing the magnitude of the vector. Vectors are widely used in mathematics and physics to describe quantities such as velocity, force, and displacement.
How are the size and directions of a force represented?
The size of a force is typically represented by the length of an arrow, with longer arrows indicating greater force. The direction of a force is indicated by the angle of the arrow, with the arrow pointing in the direction in which the force is acting.
What two pieces of information do you need to descride force?
To describe force, you need to know both the magnitude (the strength or size of the force) and the direction in which the force is acting.
When adding vector in one dimension what could the position of the head of the arrow represent?
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.
What does the length and the arrow of a vector represent?
The length of a vector represents its magnitude or size, while the arrow of a vector indicates its direction in space. Combining both the length and arrow provides a complete description of a vector's characteristics.
What is a vector composed of?
A vector is composed of both magnitude (length) and direction. It is represented by an arrow that starts at the origin and points to a specific location in space. Vectors are used to describe quantities that have both size and direction, such as velocity and force.
Why are vectors considered to be vectors?
Vectors are considered vectors because they have both magnitude (size or length) and direction. This property distinguishes vectors from scalars, which only have magnitude. In physics and mathematics, vectors are essential for representing physical quantities like force, velocity, and displacement that have both size and direction.
When adding vectors in one dimension what could the position of the head of the arrow represent?
When adding vectors in one dimension, the position of the head of the arrow represents the final displacement or position based on the individual vector components. It shows the combined effect of the vectors acting in the same direction or opposite directions.
What is vector physical?
A vector in physics is a quantity that has both magnitude and direction. It is represented by an arrow pointing in a specific direction, with the length of the arrow indicating the magnitude of the vector. Vectors are used to represent various physical quantities such as force, velocity, and acceleration in physics.
What is a vector described by?
A vector is described by its magnitude (size) and direction in space. This can be represented by an arrow with a specific length and orientation. Vectors are commonly used in mathematics, physics, and engineering to represent quantities that have both magnitude and direction.
What is a quantity that is specified by size and direction?
. Velocity Acceleration
