What is the momentum of a resting particle?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
What causes variation in velocity of particle?
Acceleration and so a force acting on the particle.
What is the approximate velocity of sound in the air?
the velocity of sound in the air is 300m/s
What is the value of orbital velocity?
the approximate value of orbital velocity is about 8km/hr.
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.

What is the approximate minimum stream velocity needed to keep a 6.4-cm-diameter particle in motion?
hey....
What is the approximate minimum water velocity required for sand particles with a diameter of 0.1 mm to be picked up and moved?
10 centimeters/second
How might speed at which a gas particle moves affects how quickly that gas particle escapes from the balloon?
Flow rate is diameter of hole*velocity, so the higher the velocity the higher the flow rate.
What is the momentum of a resting particle?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
When is the velocity vector of a particle tangent to the path of the particle?
Allways...
What causes variation in velocity of particle?
Acceleration and so a force acting on the particle.
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.
