Motion in one dimension

• Scalar Quantities— Physical quantities which only have magnitude, but no direction

Example: speed, distance, current, work

• Vector Quantities— Physical quantities that have both magnitude and direction

Example: Velocity, displacement, acceleration, force

• Objects are either at rest or in motion.
• Types of motion:
• When an object moves along a straight line, it possesses rectilinear motion.
• Object moving in a curve is called a curvil…
