Acceleration

• Acceleration is a vector quantity, meaning it has a size (magnitude) and a direction
• Acceleration is calculated using the equation: acceleration (m/s) = Change in velocity (m/s) / time taken (s)
• Acceleration units are meters per second per second (m/s²), indicating the change in velocity each second
• Acceleration can also be written as: a = (final velocity - initial velocity) / time
• Acceleration can cause objects to slow down, known as deceleration, with a negative acceleration value
• The equation relating acceleration, initial velocity, final velocity, and distance traveled is: (final velocity)² - (initial velocity)² = 2 × acceleration × distance
• Acceleration due to gravity is a constant 9.8 m/s² near the Earth's surface, represented by the symbol g
• In calculations, acceleration due to gravity is often rounded to 10 m/s²
