What else can I help you with?
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. 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.
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. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
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?
Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
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.
