Which of the following is true of two objects of different masses fall...
Velocity of Objects Falling Freely Near the Surface of the Moon
The correct statement among the options provided is that the two objects of different masses falling freely near the surface of the moon have the same velocities at any instant.
- Acceleration: In a vacuum near the surface of the moon, all objects fall with the same acceleration due to gravity, regardless of their masses. This acceleration is about 1.6 m/s² on the moon, compared to 9.8 m/s² on Earth.
- Force: Since both objects experience the same acceleration due to gravity, they do not necessarily experience forces of the same magnitude. The force experienced by an object is determined by its mass and the acceleration acting on it, according to Newton's second law of motion (F = ma).
- Velocity: Despite having different masses, the two objects will have the same velocity at any given instant while falling freely near the surface of the moon. This is because their accelerations are the same, causing them to fall at the same rate and reach the ground at the same time.
- Inertia: Inertia is an object's resistance to changes in its state of motion. While the objects may change their inertia as they fall due to the gravitational force acting on them, their masses do not affect this property in the context of falling freely near the moon's surface.
Therefore, the statement that the two objects have the same velocities at any instant is true when considering objects of different masses falling freely near the surface of the moon.
