What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
What will happen if all components of a vector are reversed in direction?
Then the resultant vector is reversed.
What is vector multiplication?
Vector multiplication is one of several techniques for the multiplication of two vectors with themselves. A vector has a magnitude and direction.
If vector is a quantity that has both size and direction?
... then what is the question?
What type of measurement is 12 feet up?
A vector has magnitude and direction, so since it is up it is vector.
Is constant speed constant velocity?
No. Velocity includes a direction vector, which speed does not have.
Can a velocity of a body change its speed is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
Can speed of a body change if its velocity is constant?
No, if the velocity of a body is constant, then its speed cannot change. Speed is a scalar quantity that represents how fast an object is moving regardless of direction, while velocity is a vector quantity that includes both the speed and direction of motion. If the velocity is constant, then the speed remains the same.
When an object increases in speed what does the accleration vector do?
When an object increases in speed, the acceleration vector remains in the direction of the object's motion. If the object is accelerating uniformly, the acceleration vector will remain constant in magnitude and direction. If the acceleration is not constant, the vector will change accordingly.
If a car drove a around in a circle would that be constant velocity?
No, if a car is driving in a circle, it is changing direction constantly. Velocity is a vector quantity that includes both speed and direction, so if the direction is changing, the velocity is not constant.
Why the speed of an object is constant while the velocity is not?
Speed is the magnitude of velocity, so if the speed of an object is constant, it means that the object is moving at a consistent rate. Velocity, on the other hand, is a vector quantity that includes both speed and direction, so if the direction of an object changes, its velocity changes even if the speed remains constant.
What is nature of velocity in constant speed?
Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.
Can the direction of the body change when the acceleration is constant?
Yes, the direction of the body can change even when the acceleration is constant. This is because acceleration is a vector quantity that includes both magnitude and direction. As long as there is a change in velocity, the body's direction can be altered, even if the magnitude of acceleration remains constant.
Can an object have a constant speed and the varying velocity at the same time explain?
Yes, an object can have constant speed but varying velocity if it changes direction. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity will vary.
What is moving every point a constant distance in a specified direction or addition of a constant vector to every point?
the answer is translation, i had to know the answer to that question for a worksheet
Can an objeact have constant speed and but variable velocity?
No, if an object has constant speed, its velocity must also be constant. Velocity is a vector quantity that includes both speed and direction. If the speed is constant, the direction must also be constant for the velocity to be constant.
Does a car moving around the block drives at constant velocity?
It could move with a constant speed and not at constant velocity. Because the direction is ever changing. Speed is a scalar but velocity is a vector quantity which has direction aspect too.
