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.

What is the speed of particles motion known as?
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.
Can the speed of the particle ever be negative if so give an example if not explain why?
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.
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..
Why is a particle in uniform circular motion not moving at a constant velocity?
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
Can a particle in one dimensional with zero speed may have non zero velocity?
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.
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.

Motion of charge particle in an electric field?
When a charged particle is placed in an electric field, it experiences a force due to the field. This force causes the particle to accelerate in the direction of the field if the charge is positive, or in the opposite direction if the charge is negative. The motion of the particle will depend on its initial velocity and the strength and direction of the electric field.
What is motion of particle without force?
A particle in motion without any external force acting on it will continue moving at a constant velocity in a straight line, following Newton's first law of motion. This motion will remain unchanged unless an external force is applied to alter its velocity or direction.
Path of a particle moving under influence of force fixed in magnitude and direction?
The particle would move in a circular path at a constant distance from the force's origin. This is because the force is always acting perpendicular to the particle's velocity, causing it to change direction but not speed. This results in circular motion.
A wave that vibrates in a direction parallel to the direction of the wave itself is called a?
Disturbance in particle motion parallel to the wave velocity is called a longitudinal wave. Disturbance in particle motion perpendicular to the wave velocity is called a transverse wave.
In velocity do you put the direction?
No, velocity includes both the speed and direction of an object's motion. It is a vector quantity, which means it has magnitude and direction. So, when stating the velocity of an object, both the speed and the direction must be included to fully describe its motion.
Consider the instantaneous velocity of a body this velocity is always in the direction of what the net force at that instant the least resistance at that instant or the motion at that instant?
The instantaneous velocity of a body is always in the direction of the resultant force acting on it at that instant. It is influenced by the net force and not necessarily by the least resistance or the current motion of the body.
