Are the following statement True (or) False?
(1) There are two types of motion.
(2) Uniform motion is motion at constant speed.
(3) Average velocity is a vector quantity.
(4) Acceleration is a scalar quantity.
(5) Displacement is the rate of change of velocity.
(6) Acceleration has only magnitude.
(7) If the speed changes, there will be acceleration.
(8) The motion at constant acceleration is the uniform motion.
(9) The SI unit of acceleration is cm s-1.
(10) Motion along a straight line with constant acceleration is linear motion.
(11) When a body is in motion there is a change in position.
(12) The change in position along a certain directi
