Variation in velocity of a particle can be caused by changes in the magnitude or direction of the force acting on the particle, inertia of the particle, or interactions with other particles in the system. Additionally, external factors such as friction, air resistance, and gravitational forces can also influence the velocity of a particle.

What causes variation in velocity of particle?
Variation in velocity of a particle can be caused by external forces acting on the particle, such as gravity or friction. Additionally, changes in direction or acceleration can also lead to changes in velocity. In a vacuum, an object will continue at a constant velocity due to inertia.
What is the momentum of a resting particle?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
How does an alpha particle move in a magnetic field?
An alpha particle is a positively charged particle, so it will experience a force perpendicular to both its velocity and the magnetic field direction. This force causes the alpha particle to move in a circular path due to the magnetic field's influence. The radius of the circle will depend on the velocity of the alpha particle and the strength of the magnetic field.
Is it true or false that For a particle in uniform circular motion the instantaneous-acceleration vector is directed radially outward?
True. In uniform circular motion, the particle's velocity is tangential to the circular path, and the acceleration is directed radially inward, towards the center of the circular path. This centripetal acceleration causes the change in direction of the particle's velocity, but the magnitude of the velocity remains constant.
What will happen to the wavelength associated with a moving particle if its velocity is reduced to half?
If the velocity of a moving particle is reduced to half, the wavelength associated with it will remain the same. The wavelength of a particle is determined by its momentum, not its velocity.

When is the velocity vector of a particle tangent to the path of the particle?
The velocity vector of a particle is tangent to the path of the particle at any point. This is because velocity is a vector that points in the direction of motion of the particle at that particular instant.
What is the momentum of a resting particle?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.

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?
The instantaneous acceleration of the particle is equal to 0 when the velocity of the particle is at a maximum or minimum. This occurs at the points on the graph where the slope of the velocity-time graph is horizontal or the velocity reaches a peak or trough.
What is the angle between particle velocity and wave velocity in transverse wave?
The angle between particle velocity and wave velocity in a transverse wave is 90 degrees. This means the particle vibration is perpendicular to the direction in which the wave propagates.
Can particle with velocity or speed at zero be accelerating?
Yes, a particle can have a velocity of zero and still be accelerating if its speed is changing. Acceleration is the rate at which the velocity of an object changes over time, so even if the particle's velocity is momentarily zero, if it is changing, it is experiencing acceleration.
Can particle have zero speed and non zero velocity?
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
What is the magnetic force on a particle with charge q and velocity v moving perpendicular to a uniform magnetic field b?
The magnetic force ( F ) on a charged particle moving perpendicular to a uniform magnetic field is given by the equation ( F = qvB ), where ( q ) is the charge of the particle, ( v ) is the magnitude of its velocity, and ( B ) is the strength of the magnetic field. The direction of the force is determined by the right-hand rule, which indicates that it is perpendicular to both the velocity of the particle and the magnetic field. This force causes the particle to move in a circular path, with the radius of the path depending on the mass of the particle and the values of ( q ), ( v ), and ( B ).
When does a particle in motion have non-uniform velocity?
That simply means that its velocity is changing.
