What is initial point in physics?
What is initial point in physics?
1. The first point at which a moving target is located on a plotting board. 2. A well-defined point, easily distinguishable visually and/or electronically, used as a starting point for the bomb run to the target.
What is initial point and final point?
INITIAL POSITION is that from a point a body is released or started. FINAL POSITION is that a body stopped or covered a distance from a point to another point.
What is the meaning of initial?
Initial is something that occurs first or at the beginning. If someone asks you to initial a form, they’re asking you to sign by writing your initials on it.
What is the initial point of a graph?
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y-value of the point where the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope.
What is the starting point of a vector?
A vector is always shown by an arrow when it is represented by a line segment. The starting point of a vector is known as initial point and the end point is known as terminal point.
Is the position a vector Why?
The position of an object is given relative to some agreed upon reference point. Position is a vector quantity. It has a magnitude as well as a direction. The magnitude of a vector quantity is a number (with units) telling you how much of the quantity there is and the direction tells you which way it is pointing.
What is the end of a vector called?
In my experience we have generally called the source or beginning of a vector its “tail” and the destination or end of the vector its “head”. They are sometimes called the initial and terminal points. The initial point is the point at which starts and the terminal point is the point at which it ends.
What is the point of a vector?
A point is a location in a coordinate system, that is a location defined relatively to an origin. If you were to move the origin without moving the point, then the coordinates of the point would change. A vector is a more general object. No matter where you draw a vector →v on a plane, it is still the same.
Is a line a vector?
Vectors are not lines and they have a very different function than lines. A vector is a direction and a magnitude, that’s it. A line, of course, has direction and magnitude, but it also has LOCATION. A vector can be anywhere, but a line exists within space.
How do you turn a point into a vector?
Find the directional vector of if points A and B are and , respectively. Explanation: To find vector , the point A is the terminal point and point B is the starting point. The directional vector can be determined by subtracting the start from the terminal point.
Can any two vectors be added?
Two vectors can be added together to determine the result (or resultant).
How vectors are added?
To add vectors, lay the first one on a set of axes with its tail at the origin. Place the next vector with its tail at the previous vector’s head. When there are no more vectors, draw a straight line from the origin to the head of the last vector. This line is the sum of the vectors.
What is the sum of two vectors maximum and minimum?
The sum of two vectros is maximum , when both thectros are in the same direction and is minimum when they act in opposite directions.
What is the angle between two vectors when their sum is minimum?
180 degree
Can the sum of two vectors be a scalar?
No, it is impossible for the magnitude of the sum to be equal to the sum of the magnitudes.
When can the addition of two vectors be zero?
Addition of two vectors can only be zero when there directions are opposite and their magnitude is additive inverse of each other.
Can the resultant of two vectors is zero?
Yes the resultant between any two vectors can be zero.
Can three unequal forces add up to zero?
Yes! resultant of three unequal forces can be equal to zero. for example. If the third force is equal in magnitude to the resultant of those two forces and exactly opposite in direction then they will cancel each other and we will get 0 net force.
What is the minimum number of unequal vectors that can give zero?
three
What should be the least number of unequal vectors in same plane whose resultant could be zero?
we can take more than 2 vectors of unequal magnitude for the resultant to be zero.. so the minimum no. of vectors of unequal magnitude for the resultant to be zero and maximum is infinity.
Can two vectors of unequal magnitude add up to give the zero vector can three unequal vectors add up to give the zero vector?
Answer. a) No. Two vectors of unequal magnitude can never add up to give zero vector. Three(or more) vectors of unequal magnitude may add up to give zero vector.
Can two nonzero perpendicular vectors be added together so their sum is zero?
Can 2 non-zero perpendicular vectors be added together so that their sum is zero? ANSWER: No. The sum of two perpendicular non-zero vectors can never be zero.
Can a scalar product of two vectors be negative?
Answer. If the angle between two vectors is acute, then their scalar product (also called dot product and inner product) is positive. If the angle between two vectors is obtuse, then their scalar product is negative.
How do you know if a vector is negative?
A negative sign will reverse the direction of a vector and make it a negative vector. Vectors are only negative with respect to another vector. For example, if a vector PQ points from left to right, then the vector QP will point from right to left. Since these directions are opposite, we say that PQ = –QP.
