I came across some questions where one box's magnitude of acceleration differed from another box's magnitude of acceleration. Please explain why and how this can be true.
Thank you.
Thank you.
Newton's 2nd law involving pulley states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In simpler terms, the greater the force applied to an object, the greater its acceleration will be, and the more mass an object has, the less it will accelerate.
A pulley can change the direction of the force applied to an object, which can affect the acceleration of the object. For example, a single fixed pulley can change the direction of a downward force to an upward force, making it easier to lift an object with less force.
No, a pulley does not change the magnitude of the force applied to an object. The amount of force required to lift an object remains the same, but the pulley can make it easier to apply the force in a different direction.
The number of pulleys can affect the mechanical advantage of a system, which can impact the force required to lift an object. For example, a system with multiple pulleys can reduce the force needed to lift an object by distributing the weight among multiple ropes.
Yes, friction can impact the application of Newton's 2nd law involving pulley. Friction can cause the ropes to stretch or slip on the pulleys, which can affect the amount of force needed to lift an object and the acceleration of the object.
