Suppose an object is moving by you at high speed. Which of the following statements are true? Select all that apply. Select all that apply. If you could measure the object's mass, you would find it to be larger than its rest mass. You would measure the moving object to be contracted in length, width, and depth compared to its size at rest. If two events occur simultaneously in the reference frame of the moving object, you might observe one event to occur before the other. You will obseve time on the moving object to be running more slowly than your time. You will obseve time on the moving object to be running more rapidly than your time. If you could measure the object's mass, you would find it to be smaller than its rest mass. You would measure the moving object to be shorter in the direction of motion than it would be if you measured it at rest.
