What happens when three blocks are placed on a horizontal frictionless surface?
When three blocks are placed on a horizontal frictionless surface, they will remain stationary and not move because there is no force acting on them to cause them to move.
Can a frictionless surface exert normal force?
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
What happens when three blocks are placed on a frictionless horizontal surface?
When three blocks are placed on a frictionless horizontal surface, they will remain stationary unless an external force is applied to them. If a force is applied to one of the blocks, it will move in the direction of the force, while the other blocks will remain stationary due to the absence of friction.
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.
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.
Where does friction happen?
Everywhere! Frictionless surfaces do not exist.
Can acceleration happen on a frictionless surface?
yes
What happens when three blocks are placed on a horizontal frictionless surface?
When three blocks are placed on a horizontal frictionless surface, they will remain stationary and not move because there is no force acting on them to cause them to move.
Is conservation of mechanical energy likely to hold if a hockey puck slid on a frictionless surface of ice?
yes

No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
It is possible to make a frictional less surface on which a ball will roll without end?
It is impossible to create a frictionless surface upon which a ball will roll without stopping. This is firstly because no two surfaces have a fritional constant of zero in that there is no surface which is perfectly smooth. Also, even if there were a true frictionless surface, a ball would not be able to roll along it forever due to air resistance.

What will happen if you apply a force on top of a disk kept on a frictionless surface?
The disc will slow down as a result of the friction applied by the force.

What situation is friction is not needed?
Rotating bearings.
