From the below diagram, a body moves from A to B in a straight line path, the length of line joining the initial position A and to the final position B is called
Displacement
Distance
Velocity
Jerk
Acceleration is a
Scalar quantity
Vector quantity
Uniform velocity
None of these
A particle has a value of 46.0 ms-1. It may be the
force of the particle
velocity of the particle
momentum of the particle
