Answer:
Hello! Here are your answers!
SCALAR: Scalar quantities have a size or magnitude only.
VECTOR: Vector quantities have both magnitudes and direction.
Explanation:
They are alike as they are both used to explain physical quantities and represent the magnitudes or sizes of the physical quantities...
They are different as VECTOR quantities describe an objects DIRECTION as well as magnitude whilst SCALAR doesn't
ie...SCALAR: MASS, TIME
VECTOR: VELOCITY, ACCELERATION...
I HOPE THIS HELPS!!
