FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

Physics 1 – Mechanics and Heat Lecture Notes Prepared by: ENGR. HAROLD JAN R. TERANO‚ ECE Lesson 5 ROTATIONAL KINEMATICS AND DYNAMICS Uniform Circular Motion – an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration

is higher than that of the sand (840 ). Specific heat is the amount of heat needed to raise the temperature of a unit mass of a substance by one degree. You’re also only heating the surface of the sand to a depth of a few inches. With the sea‚ the motion of it ensures that the heat energy is dispersed more efficiently.
