The velocity gives the speed and the direction of the body.
(14) Displacement has only magnitude.
(15) Speed is a vector quantity.
(16) Average velocity has only direction.
(17) Acceleration is the rate of change of speed.
(18) Average speed and average velocity have the same unit.
(19) Speed may not be measured in ms-2.
(20) Although speed changes , there is no acceleration.
(21) The speed of a body tell us how far it travels during every unit of time.
(22) The slope of the displacement time graph gives the acceleration of the body .
(23) If the speed changes, the velocity also changes.
(24) The units of speed and velocity are the same.
(25) The area under the speed-time graph gives velocity.
