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.
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..
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.
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.
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.
Velocity differs from speed in that velocity indicates?
Velocity is a vector quantity, which means that a body's speed and direction are both required to define it. They are different because: Speed is the rate of change of distance with time but velocity is the rate of change of displacement with time.

Are velocity and speed the same?
Speed and velocity are similar in terms of the rate at which an object is moving, commonly expressed in terms such as miles per hour (mph) or feet per second (fps). Velocity differs from speed because velocity also deals with direction, specifically with respect to a point of origin.
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.
Explain the difference between velocity and speed?
they are different words with the same meaning.
Is it possible in straight line motion a particle have zero and 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..
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.
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.
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.
Is final velocity equal to speed tell you yes or no?
No. (We'd like to explain why, but the question doesn't permit it.)
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.
