To calculate the acceleration of an object moving vertically upward or downward, we need to consider the forces acting on the object.
- Moving vertically upward: When an object is moving vertically upward, the acceleration is typically negative (opposite to the direction of motion). This is because the object is usually decelerating or moving against the force of gravity.
The acceleration can be calculated using the following equation: a = g - F/m
Where: a = acceleration g = acceleration due to gravity (approximately 9.8 m/s² near the surface of the Earth) F = net force acting on the object m = mass of the object
- Moving vertically downward: When an object is moving vertically downward, the acceleration is typically positive (in the same direction as the motion). This is because the object is accelerating due to the force of gravity.
The acceleration in this case is equal to the acceleration due to gravity, which is approximately 9.8 m/s² near the surface of the Earth.
Therefore, to calculate the acceleration of an object moving vertically upward or downward, you need to consider the forces acting on the object and apply the appropriate equation based on the direction of motion.
