: Two objects, one having three times the mass of the other, are dropped from the same height in a ... (1 bookmark) Two objects, one having three times the mass of the other, are dropped from the same height in a vacuum. At the end of their fall, their velocities are equal because: Entry field with incorrect answer a) anything falling in vacuum has constant velocity b) all objects reach the same terminal velocity c) the acceleration of the larger object is three times greater than that of the smaller object d) the force of gravity is the same for both objects e) none of the above
Why is D not the right answer please?

Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.

Two masses, one twice as massive as the other, move towards each other. For both objects to come to rest after they collide inelasticaly, what must the velocity of the smaller object be relative to the velocity of the larger object? Explain your reasoning.

2. Galileo famously dropped two spheres of different weights (but of the same size) off of the Leaning Tower of Pisa in order to show that Aristotle's theory of gravity (that objects fall at rates proportional to their weights) was wrong. Suppose one sphere had mass m = 1 kg and the other had mass m = 5 kg, and that their velocities followed the equation: mv' = mg - kv with constant of proportionality k = 0.1 kg/s and...

Two objects are dropped simultaneously from an initial height of 100m, with an initial velocity of zero. They fall straight down. For mass 1, you can ignore air drag. For mass 2, air drag DOES affect the motion.

When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...

Question 1. The validity of the four kinematic equations depends on a basic assumption made about the object being described which is: Question 1 options: A) the object must be on the earth, otherwise, we must use “graviton physics”. B) the object has a constant acceleration, otherwise, we must use more complex equations. C) the object has a mass that is greater than 10-10 kg, otherwise, we must use “particle physics”. D) the object has a velocity greater than zero,...
