For a start, it is not possible to propel it indefinitely. Where should the energy come from?
On the other hand, there is a speed limit in the Universe, called the "speed of light". An object can approach the speed of light, but never quite reach it, much lass pass that speed.
Increasing an object's velocity has a greater effect on its kinetic energy than increasing its mass. This is because kinetic energy is directly proportional to the square of the object's velocity, while it is linearly proportional to the object's mass.
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
Nothing gives an object inertia. Inertia is not a force. It is just the tendency of an object to continue in its motion if there is no force acting upon it.
Nothing will happen to the object's motion, it will continue along its path.
It would continue to orbit, as the gravity at the distance to the moon would remain the same.
A geometrical object that is straight, infinitely long and infinitely thin.
A projectile is a fired, thrown, or otherwise propelled object that is intended to hit a target. Examples of projectiles include bullets, arrows, and cannonballs.
Velocity increases but not infinitely.
You can increase the momentum of an object by either increasing its mass or its velocity. By increasing the mass of the object, the momentum will increase proportionally. Alternatively, increasing the velocity of the object will also increase its momentum.
It's true that gravity is comparatively weak. But it makes up for its weakness by extending its influence out infinitely far. The gravity weakens the farther you get from an object, but theoretically, you can continue to calculate the gravitational force no matter how far you are from the object you are considering.
When an object falls, it accelerates due to gravity pulling it downwards. As it falls, the object's potential energy is converted into kinetic energy, increasing its speed. The object will continue to fall until it reaches the ground or encounters another force that counteracts gravity.
The momentum (given by the property of inertia) makes whatever was propelled by the rocket continue at the same velocity as before, until another force (like running into a planet) affects that object.
A line.
Increasing the speed of an object does not affect that object's mass. Mass is an intrinsic property of an object and remains constant regardless of its speed.
Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.
No, an object propelled vertically will not normally move at a constant pace. Due to the influence of gravity, the object will experience acceleration while moving upward and deceleration while moving downward. This will result in a continuously changing velocity throughout its motion.
Increasing the mass of an object will increase its inertia. Also, increasing the speed at which an object is spinning will increase its rotational inertia. Additionally, increasing the distance of an object from the axis of rotation will increase its rotational inertia.
