When there is no air resistance objects with different masses fall with.......

A. equal accelerations and different displacements
B. equal accelerations and similar displacements
C. different accelerations and similar displacements
D. different accelerations and displacements

B is the answer

B is probably the best answer. If "masses fall" had been followed by "from rest", then B is the exact answer. Falling does not imply zero initial velocity. Objects thrown upward fall at a constant rate, but their displacement with time is quite different from objects falling from rest.

Your questions are quite poorly written. I am wondering if the person writing them understands physics.

Well, if it's any consolation, physics can be quite a tricky subject to grasp. It's like trying to catch a slippery banana peel while wearing roller skates. But don't worry, I'm here to help peel away the confusion!

When there is no air resistance, objects with different masses actually fall with the same acceleration. Yes, you heard that right! It's like a synchronized dance routine, but with gravity as the choreographer. So the correct answer is... *drumroll*... C. different accelerations and similar displacements.

But don't fret if it seems counterintuitive! Sometimes, even physics likes to throw us a curveball. Just remember, in the world of science, anything is possible... except maybe finding your missing socks. Those things have vanished into a parallel universe entirely of their own.

Based on the given options, the correct answer is B. When there is no air resistance, objects with different masses will fall with equal accelerations and similar displacements.

In the absence of air resistance, the only force acting on a falling object is the force due to gravity, which is the same for all objects regardless of their mass. According to Newton's second law of motion, F = ma, where F is the force, m is the mass, and a is the acceleration. Since the force is the same for all objects, the acceleration will also be the same.

Similarly, when objects fall from the same height, they will experience the same gravitational force and therefore have similar displacements.

To get the answer to this question, you can use the concept of free fall and neglect the effects of air resistance. In free fall, all objects near the surface of the Earth experience the same acceleration due to gravity, which is approximately 9.8 m/s^2. This means that regardless of their mass, objects will accelerate towards the ground at the same rate.

So, the correct answer is B - objects with different masses fall with equal accelerations and similar displacements. The similar displacements refer to the fact that, neglecting air resistance, all objects will fall a similar distance in a given time interval if they are released from the same height. However, it's important to note that if objects are not released from rest or have different initial velocities, their displacements will vary.

In summary, when there is no air resistance, objects with different masses will fall with equal accelerations and similar displacements.
