Speed and velocity cannot be compared because they are different things. It is like saying "apples > Oranges". Velocity is a vector and, as such, it has a direction and a size. The size of the vector velocity is it's speed.
To answer your question: no because they can't be compared. And if you wanted to ask if the size of the velocity vector being smaller than the speed... no... that is the definition of speed... so it cannot be different, regardless of the number of dimensions you are using.
No, a particle in one dimension with zero speed will have zero velocity. Velocity is a vector quantity that includes both the speed and direction of motion, so if the speed is zero, the velocity will also be zero since there is no direction of motion.
The speed of particle motion is known as velocity. Velocity is a vector quantity that specifies both the speed and direction of an object's motion.
No, the speed of a particle cannot be negative. Speed is a scalar quantity and is always positive, representing the magnitude of the velocity of an object. Negative values are used to represent the direction of motion in one-dimensional motion.
This is true by definition. Motion is defined by difference in position occurring as a function of time, and "velocity" is is thethree-dimensional vector which quantifies that motion. To simplify the concept to a single dimension, if "x" is the position of a particle on a line at any instant of time, then the velocity of the particle is defined as dx/dt, that is, the change in position x divided by the change in time as the change in time approaches zero as a limit.
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..
The measure of energy of motion of a particle of matter is called kinetic energy. It is calculated using the formula KE = 0.5 * mass * velocity^2, where mass is the mass of the particle and velocity is its speed.
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
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.
Are you talking about the Illinois Particle accelerator? Well I think that it doesn't go at a constant speed but at a constant Acceleration, since it is accelerating and not staying at one speed is is therefor Constant Acceleration until they slowly work it up to almost the speed of light.
Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.
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..
Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.
