Velocity

• Speed is a scalar quantity that represents how fast or slow something moves, while velocity is a vector quantity that describes both speed and direction.
• The SI unit for speed is meters per second (m/s), while the SI unit for velocity is also meters per second (m/s).
• Acceleration is defined as the rate at which an object changes its velocity over time.
• Velocity can be calculated by dividing displacement by time, using the formula v = d / t.
• Velocity can be calculated by dividing displacement by time.
• Acceleration is measured in meters per second squared (m/s^2) in the metric system.
