Only if it is in balance - a lever does not have to balance.ultrauser said:If I have 10m lever with a center of the mass 2m from the right side it must mean the shorter arm have greater mass to keep balance.
No.Does it mean longer (lighter) arm have greater gravitational acceleration cause it must travel greater distance in the same time ?
According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This means that if the mass of an object increases, its acceleration will decrease when using a lever.
It ultimately depends on the specific situation and goal. If the goal is to lift or move a heavy object, then a greater mass is preferred to generate a larger force. However, if the goal is to achieve a faster acceleration, then a smaller mass and greater force is needed.
The length of a lever does not directly affect its acceleration when using a greater mass. However, it does impact the amount of force needed to lift or move the object. A longer lever can provide a mechanical advantage, requiring less force to achieve the same acceleration as a shorter lever.
The amount of acceleration produced by a lever is directly proportional to the amount of force applied. This means that if the force is increased, the acceleration will also increase, as long as the mass remains constant.
Yes, the use of a lever can overcome the effects of greater mass by providing a mechanical advantage. By increasing the length of the lever or using a different fulcrum point, the lever can generate a larger force to overcome the mass and achieve the desired acceleration.
