Drift velocity refers to a particle's average velocity being influenced by its electric field. Momentum relaxation time is the time required for the inertial momentum of a particle to become negligible.
If a be the amplitude of a particle executing SHM with an angular velocity w and yis the displacement, then velocity of the particle at any instant is given by u(t)=w J(a 2 y 2
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
Disturbance in particle motion parallel to the wave velocity is called a longitudinal wave. Disturbance in particle motion perpendicular to the wave velocity is called a transverse wave.
If the velocity equals zero, the acceleration is also zero because the velocity hasn't changed, thus, the particle isn't accelerating anywhere. This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time. An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.
hey....
10 centimeters/second
Flow rate is diameter of hole*velocity, so the higher the velocity the higher the flow rate.
Allways...
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
Acceleration and so a force acting on the particle.
That simply means that its velocity is changing.
yes. If the forces acting on the a moving particle are in equilibrium, (e.g. when a spherical object reaches terminal velocity (neglecting increased air resistance as it gets closer to the ground)) then the particle will be moving at a velocity, that is not 0, yet the velocity will remain constant, and the body will not accelerate or decelerate in any direction, and thus the acceleration is 0.
the velocity of sound in the air is 300m/s
the velocity of sound in the air is 300m/s
the approximate value of orbital velocity is about 8km/hr.
To find the acceleration of a particle using the vector method, you can use the equation a = r x (w x v), where "a" is the acceleration, "r" is the position vector, "w" is the angular velocity vector, and "v" is the velocity vector. The cross product (x) represents the vector cross product. By taking the cross product of the angular velocity vector with the velocity vector and then multiplying the result by the position vector, you can find the acceleration of the particle.
