Frictionless motion describes a situation where there is no resistance or opposition to an object's movement. This can occur in idealized scenarios, such as in a vacuum or with certain lubricated surfaces, where friction is eliminated. In these cases, objects can continue moving indefinitely without the need for an external force to maintain their motion.
What else can I help you with?
What is the amount of force needed to keep a ball moving that has been launched into frictionless space?
In the vacuum of frictionless space, no force is needed to keep the ball moving. According to Newton's First Law of Motion, an object in motion will stay in motion unless acted upon by an external force. Therefore, once the ball is launched into frictionless space, it will continue moving indefinitely.
Is force different in a frictionless floor?
Yes, in a frictionless environment, there is no force opposing motion, so objects will continue to move at a constant velocity unless acted upon by an external force. This means that less force is required to maintain or change an object's motion on a frictionless floor compared to a floor with friction.
After a cannonball is fired into frictionless space the amount of force needed to keep it going is?
Once a cannonball is fired into frictionless space, no additional force is needed to keep it moving at a constant velocity. According to Newton's first law of motion, an object in motion will remain in motion with the same speed and in the same direction unless acted upon by an external force.
Is anything frictionless?
In theory, there is no such thing as completely frictionless motion. Friction is a force that resists the relative motion of two surfaces in contact, and it is present in all physical systems to some extent. Even in scenarios where friction seems negligible, such as in outer space or at the atomic level, there are still microscopic interactions that result in some level of friction. Therefore, while we can approach near-frictionless conditions in certain controlled environments, true frictionlessness is not achievable in reality.
What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
No work is done against gravity when a body is moved horizontally along a frictionless surface because the force of gravity acts perpendicular to the direction of motion. Work is only done when a force is exerted in the direction of motion.

How much force is required to keep a body moving with constants speed on a frictionless surface?
On a frictionless surface, no force is required to keep a body moving with constant speed. According to Newton's first law of motion, an object in motion will remain in motion unless acted upon by an external force. Thus, in the absence of friction, the body will continue to move at a constant speed indefinitely.
What is the accereleration of 2kg mass slding down a frictionless ramp?
The acceleration of a 2kg mass sliding down a frictionless ramp is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2. This acceleration remains constant as there is no force acting against the motion of the mass on a frictionless surface.
How can the use of frictionless pulleys improve the efficiency of a mechanical system?
Frictionless pulleys can improve the efficiency of a mechanical system by reducing the amount of energy lost to friction. This allows for smoother movement and less resistance, resulting in a more efficient transfer of force and motion within the system.
Will a skateboard go faster if you push it with the same force for a longer time?
Yes. The force is measured as "acceleration" and is meters per second per second (or velocity per second) or the first derivative of velocity. On a frictionless surface in an environment without air resistance, and if the skateboard is a frictionless mechanism, if the skateboard is moving at a constant velocity, that means the acceleration is zero, which means that there is no force being applied to it and it is a body in motion staying in motion.
How do three blocks in contact with each other on a frictionless surface affect the overall system's motion and stability?
When three blocks are in contact with each other on a frictionless surface, they can move together as a single unit without any resistance. This can affect the overall system's motion by allowing it to move smoothly and without any hindrance. However, the stability of the system may be compromised as the blocks can easily slide or shift position due to the lack of friction.
How can one effectively demonstrate Newton's first law of motion?
One can effectively demonstrate Newton's first law of motion by showing that an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. This can be done by conducting experiments with objects on a frictionless surface or by observing the motion of objects in space.
Is there any frictionless train?
No there is always a resistive force such as air resistance. The closest frictionless train is the japanese magnetic train which has no friction on the track.
