How does mass affect a projectile if there is no air resistance?
In the absence of air resistance, mass does not affect the motion of a projectile. All objects fall at the same rate regardless of their mass in a vacuum. This principle is described by Galileo's law of falling bodies.
What is a freely falling projectile?
A freely falling projectile is an object that is only acted upon by gravity, moving through the air in a parabolic path while falling towards the ground. It does not have any initial horizontal force or acceleration other than gravity acting upon it.
Why would a feather and an elephant fall at the same time in a vacuum?
Because a feather has more air resistance, it normally falls slower, but in a vacuum, there is not air resistance so they fall at the same rate. Think of it as a feather and an elephant falling in space.
Is a feather a free falling object?
Yes, a feather is considered a free falling object in a vacuum or an environment with minimal air resistance. However, in normal atmospheric conditions, air resistance can significantly affect the feather's rate of descent.
How does air resistance affect the components of projectile motion?
Air resistance acts as a resistive force that opposes the motion of the projectile. It causes the projectile to experience a decrease in speed and alters its trajectory, leading to shorter horizontal distances and lower maximum heights compared to ideal projectile motion in a vacuum. Additionally, air resistance can cause the projectile to fall at a steeper angle compared to when it is neglected.

How could you carry out a demonstration on Earth of a feather falling at the same rate of a bowling ball?
To demonstrate a feather falling at the same rate as a bowling ball on Earth, you can create a vacuum chamber to remove air resistance. When both the feather and the bowling ball are dropped in the vacuum, they will fall at the same rate due to the absence of air drag affecting their descent, as demonstrated by Galileo's famous experiment on falling bodies.
Why can an object falling in an vacuum never reach terminal velocity?
In a vacuum, there is no air resistance to oppose the motion of the falling object, so there is no force acting to limit its acceleration and reach terminal velocity. As a result, the object will continue to accelerate indefinitely as it falls through the vacuum.
Why will a feather and an apple fall at the same rate in a vacuum?
In a vacuum, there is no air resistance to slow down the falling objects. Both the feather and the apple will experience only the force of gravity, causing them to fall at the same rate regardless of their mass. This is described by the principle of universal acceleration due to gravity.
Will a feather and steel ball fall simultaneously in vacuum?
Yes, in a vacuum both a feather and a steel ball would fall simultaneously because there is no air resistance to impede their free fall. This means they would both fall at the same rate due to gravity, as described by Newton's laws of motion.
Why does a feather having a mass of 9 grams fall from a table to the floor slower than a 9 gram ping pong ball falling the same distance?
this is because of air resistance which increases with surface area of feather. however if there is no air resistance (only vacuum) both feather and ball will fall together.
What affect would a vacuum have on falling objects?
In a vacuum, there is no air resistance or drag to slow down falling objects. This means objects would fall at their maximum acceleration rate, which is around 9.8 m/s^2, as opposed to slowing down due to air resistance in a normal environment.
Why do feather and rock hit the ground at the same time in vacuum?
In a vacuum, there is no air resistance to slow down the falling objects. Both the feather and the rock will fall with the same acceleration due to gravity, and thus hit the ground at the same time. This is because gravity affects all objects in the same way regardless of their mass.
