STATEMENT - 1 : If the body is moving in the opposite direction of positive motion, then its speed is negative. STATEMENT - 2 : A scalar quantity is one that must be dimensionless. STATEMENT - 3 : A body is momentarily at rest when it reverse its direction of motion.

The instantaneous speed of a body can be measured:-

Statement I: The displacement of a body may be zero, though its distance can be finite. Statement II: If the bodt moves such that finally it arrives at the initial point, then displacement is zero while distance is finite.

"Speed of a particle can be negative",Is thi statement correct?.If not why?'

Statement-1 : The relative velocity between any two bodies moving in opposite direction is equal to sum of the velocities of two bodies. Statement-2 : Sometimes relative velocity between two bodies is equal to difference in velocities of the two.

Statement-I : A positive acceleration can be associated with a 'slowing down' of the body. Statement-II : The origin and the positive direction of an axis are a matter of choice.

If a body is moving with constant speed, then its acceleration

Statement I: The average velocity of the body may be equal to its instantaneous velocity. Statement II: For a given time interval of a given motion, average veocity is single valued while average speed can have many values.
