Scalar Quantities- have magnitude only (a numerical value and unit) but no direction.: Mass (Example: 50 kg of rice), Temperature (Example: 25°C room temperature), Time (60 seconds), Speed (Car moving at 20 m/s), Distance (5 meters between two points), Energy (500 J of work done), Volume (2 L of water), Power (60 W light bulb), Vector Quantities- have both magnitude and direction.: Displacement (5 m north), Velocity (10 m/s east), Acceleration (3 m/s² downward), Force (20 N to the right), Momentum (8 kg·m/s west), Weight (600 N downward), Electric Field (50 N/C upward),
