Can a body moving with certain velocity in the direction of east have aeleration in the direction of west explain how?

Yes a body moving with some velocity in the direction of east have acceleration in the west because when the body will stop or exerts brakes so the body will move a little back and acceleration will be produced in the opposite direction which is west.

Explain how velocity differs from speed?
Speed is the magnitude of velocity (which has a direction as well).
Does speedometers of a car measures its velocity full explain?
No. Velocity consists of a magnitude and a direction. The magnitude of velocity is called "speed", and that's what the speedometer measures. But it displays no information concerning the direction in which the car is moving.
Explain why velocity changes while driving around a circular track even if the speed is constant?
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
Can the speed of the particle ever be negative if so give an example if not explain why?
speed cannot as it is just a magnitude, however as velocity relates both magnitude and direction, and direction can be negative, technically you can have a negative velocity.
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.

Explain the difference between velocity and speed?
they are different words with the same meaning.
Two bicycle riders have the same speed so do they have the same velocity please explain?
Not necessarily. Velocity is made up of speed and direction, so if they go in different directions, their velocity won't be the same.
Does a change in direction affect velocity explain?
Direction does not have to change when velocity is changed. You can move North at 10 m/s and change it to 8 m/s a second later. You would still be moving North. But since velocity is a vector, if direction changes, even though speed (magnitude of velocity) remains constant, then velocity most certainly changed, since both magnitude and direction make up the vector.
In direct current charges carries have a drift velocity but in alternating current there is no net velocity of the charge carriers. Explain why?
In direct current the charge carries always flow in the same direction, while in alternating current they change direction repeatedly, meaning overall there is no net direction.
Is it possible in straight line motion particle have 0 speed and a non-zero velocity .explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
Explain the effect that gravity has on the velocity of falling objects?
The force of gravity causes the falling object's velocity to grow in magnitude by 9.8 meters per second every second, while its direction remains constant.
