Question

True or False for the following statements. If false, please explain why (6% each) a) 1. A rectilinear motion is a body moving in a straight line while a curvilinear motion the body changes the directions. For a projectiie motion, the best coordinate system for analyzing it is X-Y rectanguiar coordinates for this curvilinear motion. b) t In normal-tangential coordinates, the particle will have velocity in both normal and tangential and normal directions. c) In normal-tangential coordinates, the particle will have acceleration in normal and tangential directions d) A vector has its magnitude and its direction. The magnitude of the sum of 2 vectors equals to the sum of the individual vector's magnitudes. e) f) The axes of a coordinate system don't have to be perpendicular to each other but a defined e.

Explanation / Answer

a). TRUE- Rectilinear motion is another name for straight-line motion. This type of motion describes the movement of a particle or a body. A body does not rotate about its own or any other axis. Curvilinear motion is the motion of a body on a curved path.

b). TRUE: In the projectile motion, XY coordinate system is best because acceleration is zero in X direction.

c). FALSE. In normal tangential coordinates, the particle has a velocity only in tangential direction and not in normal direction.

d). TRUE: The particle has centripetal acceleration in the normal direction and tangential acceleration in the tangential direction.
