Why is the drift velocity in an electrical wire so small?
The drift velocity in an electrical wire is small because the electrons in the wire move slowly due to frequent collisions with atoms in the wire's material, which hinders their overall movement.
Can particle with constant velocity be accelerating?
No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.
What is the difference between the velocity and the magnitude of the velocity of an object?
Velocity is a vector quantity that includes both the speed and direction of an object's motion, while magnitude of velocity refers to the speed of the object regardless of direction. So, the magnitude of velocity is the absolute value of the velocity vector without considering its direction.
Can your speed and velocity ever have the same magnitude?
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
Can an object change its direction when the magnitude of its velocity is zero?
No, an object cannot change its direction when the magnitude of its velocity is zero. This is because velocity is a vector quantity that includes both magnitude and direction. If the magnitude of the velocity is zero, it means the object is not moving at all and therefore cannot change direction.

The drift velocity in an electrical wire is small because the electrons in the wire move slowly due to frequent collisions with atoms in the wire's material, which hinders their overall movement.
How is velocity diffrent from speed?
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.

Is 6 miles per hour an example of velocity?
Velocity has magnitude and direction. Speed just has a magnitude. So without having a direction, the answer to your question is no.
Can an object change its direction when the magnitude of its velocity is zero?
No, an object cannot change its direction when the magnitude of its velocity is zero. This is because velocity is a vector quantity that includes both magnitude and direction. If the magnitude of the velocity is zero, it means the object is not moving at all and therefore cannot change direction.
As momentum of an object decreases what happens to the veocity?
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.
What is the effect on the drift velocity of free electrons by decreasing the length and the temperature of wire?
As we know , resistance(R) is directly proportional to length(L) of conductor and resistence(R) is inversely proportional to current (I) and I=nAqv (v is drift velocity) So , if we decrease the length of the conductor , resistance of the conductor will decrease and current(I) will increase and drift velocity of free electrons will increase . And as we know resistance and temperature have direct relation so , by decreasing the temperature resistence will decrease and current will increase . So drift velocity will increase .
What happends to kinetic energy when the velocity increases?
When velocity increases, kinetic energy also increases. Kinetic energy of an object is directly proportional to its velocity squared, so even a small increase in velocity can result in a significant increase in kinetic energy.
A spaceship has a momentum of 20 000 kg-ms to the left and a mass of 500 kg What is the magnitude of its velocity?
momentum = mass x velocity, so velocity is momentum/mass. If the question asks for the magnitude then it's probably the absolute magnitude rather than a directional value (which would be negative as the space ship is heading to the left.
In velocity do you put the direction?
No, velocity includes both the speed and direction of an object's motion. It is a vector quantity, which means it has magnitude and direction. So, when stating the velocity of an object, both the speed and the direction must be included to fully describe its motion.
