Scalar versus Vectors

What are scalar quantities? • These are quantities which can be described by magnitude alone (e.g.: Temperature, speed, distance).

What about vector quantities? • These are quantities which are described with both magnitude and direction (e.g.: velocity, displacement, force).

4) Gravity

Prepared by: Mr. Jayson G. Chavez for MCS

Scalar versus Vectors

4) Gravity Answer: Vector; because gravity has a direction which is towards the center of the Earth. Prepared by: Mr. Jayson G. Chavez for MCS

5) Acceleration

Prepared by: Mr. Jayson G. Chavez for MCS

Scalar versus Vectors

5) Acceleration Answer: Vector; because it is described in velocity which is a vector quantity. Recall: accel.= Vf- Vi/t Prepared by: Mr. Jayson G. Chavez for MCS
