The force required to move an object (piano)

• ebineezer
In summary, force is a physical quantity that causes a change in the motion or shape of an object. It is necessary to apply a force in the direction you wish the object to move in order to move it. The force required to move an object is not necessarily the same as its weight, as it takes into account factors such as friction and resistance. The force required to move an object, such as a piano, can be calculated using the formula F = ma, where F is the force, m is the mass of the object, and a is the acceleration. The surface the piano is being moved on can greatly affect the force required, as different surfaces have varying levels of friction. Working in a team can help reduce the force required to move

TL;DR Summary
Hi, I'm working on a kinetic sculpture, rotating a piano 360 degrees within a circular framework. The piano has 2 pulley type wheels on each corner which fit into the round rails to maintain stability. My question--is the force needed to push/pull the piano on flat horizontal rails the same as it is to rotate it on round rails? Consider the piano to be balanced.

Assuming there is no binding in the track and the track is relatively hard material, smooth and clean(there will be some rolling resistance)...the force needed is that necessary to overcame friction in the bearings(wheels) supporting the weight of the object.

1. What is the definition of force?

Force is a physical quantity that can cause an object to accelerate, change its shape, or change its state of motion.

2. What is the formula for calculating force?

The formula for calculating force is force = mass x acceleration, or F = m x a. This means that the force required to move an object (piano) will depend on its mass and the acceleration needed to move it.

3. How does friction affect the force required to move an object?

Friction is a force that opposes motion between two surfaces. This means that the presence of friction will increase the force required to move an object, as it acts in the opposite direction of the intended motion.

4. What are some factors that can affect the force required to move a piano?

The force required to move a piano can be affected by various factors such as the weight of the piano, the surface it is being moved on, the presence of friction, and the strength of the person or machine moving it.

5. How can the force required to move a piano be reduced?

The force required to move a piano can be reduced by using tools such as a dolly or a ramp, which can help distribute the weight and reduce the amount of force needed. Additionally, reducing the friction between the piano and the surface it is being moved on can also make it easier to move.
