Study Notes
Scalar vs. Vector Quantities
- Scalar quantities have only magnitude, such as temperature or mass, but no direction.
- Vector quantities have both magnitude and direction, such as force or velocity.
Motion Types
- Translational motion refers to motion where the trajectory is always a straight line; this includes types of uniform motion.
- In uniform rectilinear motion (URM), an object travels in a straight line with constant speed.
Examples of Quantities
- Scalar quantity examples include distance, speed, and energy.
- Vector quantity examples include displacement, velocity, and acceleration.
MRU (Motion in a Straight Line)
- MRU stands for "Uniform Rectilinear Motion," where an object moves with constant speed along a straight path.
Addition of Scalar Quantities
- Scalar quantities are added arithmetically by simple addition, as they do not involve direction.
