Answer:
D) The direction of the force and the direction of acceleration must be opposite of each other.
Step-by-step explanation:
According to Newton's second law of motion, the force acting on an object is directly proportional to the mass of the object and its acceleration. The equation is given as F = m * a, where F is the force, m is the mass, and a is the acceleration.
When considering gravity acceleration, such as in free fall, the force acting on an object is its weight, which is equal to the mass of the object multiplied by the acceleration due to gravity (9.8 m/s² on Earth). Since the force of gravity acts downward, the acceleration due to gravity is also downward.
Therefore, the direction of the force of gravity and the direction of acceleration due to gravity are opposite to each other. This aligns with option D) The direction of the force and the direction of acceleration must be opposite of each other.
