around 246 newtons of force
the amount needed is the amount that's taken by the bear
The different amount of force is needed because some objects have more mass and weight than others for example if you have a ball of Styrofoam and a baseball the baseball has a higher density and mass so it takes more force to move the baseball than the Styrofoam.
An inclined plane reduces the amount of force needed to move an object by increasing the distance over which the force is applied, which decreases the force required. This is because the force needed to lift an object vertically is greater than the force needed to push it along an inclined plane.
A pulley is a simple machine that changes the direction of the force needed to move an object without changing the amount of force required. By using a pulley, you can apply a downward force to lift an object upwards.
The different amount of force is needed because some objects have more mass and weight than others for example if you have a ball of Styrofoam and a baseball the baseball has a higher density and mass so it takes more force to move the baseball than the Styrofoam.
Using more pulleys in a system can decrease the amount of force needed to lift an object. Each additional pulley reduces the amount of force required by distributing the load across multiple ropes, decreasing the overall effort needed.
Decrease friction.
The amount of force that is needed to bend a steel fence post depends with the steel post in question. The force that is required is therefore calculated based on the material in question.
Wedges reduce the amount of force needed to do work by increasing the distance over which the force is applied. This allows for the same amount of work to be done with less force. The shape of the wedge allows for the force to be spread out over a larger area, making it easier to split or separate objects.
how does moving a fulcrum on a lever change the amount of force needed to move an object
by increasing distance over which the force is applied
The main of force needed tio move an object is the objects mass, f= ma.
