What is the momentum of a resting particle?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
Vector method to find out the acceleration of a particle is -wwrwhere angular velocity is w?
1) The position vector of a particle is r= (a cosώt) i+ (a sinώt) j. The velocity of the particle is and find the parallel position vector.
A particle is moving along the x-axis. The line graph shows the velocity of the particle over time. When is the instantaneous acceleration of the particle equal to 0?
5. A particle is moving along the x-axis. The line graph shows the velocity of the particle over time. When is the instantaneous acceleration of the particle equal to 0?
Who study the variation in velocity?
A change in velocity is acceleration, and would be studied by a physicist or a mechanical engineer.
What is the relationship between the particle size and wavelength?
IF and ONLY IF when the mass of particles are same. Large particle sizes will need high stream's velocity to carry it from one place to another,In another word If the stream velocity is slow than large particle sizes will be stationary.
When is the velocity vector of a particle tangent to the path of the particle?
Allways...

When does a particle in motion have non-uniform velocity?
That simply means that its velocity is changing.
If the velocity of a particle is nonzero can the particle's acceleration be zero?
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.

Momentum of the particle?
mass times the velocity of the body.
What determines the nature of path followed by the particle?
Velocity
Velocity of a fluid particle at centre of pipe is?
Maximum
Can the directions of velocity and displacement of a particle be different?
yes
