The amount of force needed to lift an object depends on its weight and the acceleration due to gravity. This force can be calculated using the formula F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity (approximately 9.81 m/s^2 on Earth).
What else can I help you with?
How do you find the minimum amount of force needed to lift an object?
The minimum amount of force needed to lift an object can be found by calculating the object's weight using the formula F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity. This force must be greater than or equal to the weight of the object to lift it off the ground.
What kind of force does a porter apply to lift an object?
A porter applies an upward force called the lifting force to lift an object. This force must be larger than the weight of the object to overcome gravity and lift it.
What is the force required to lift an object equal to?
The force required to lift an object is equal to the weight of the object, which is the mass of the object multiplied by the acceleration due to gravity (F = m * g). The force must overcome the gravitational force acting on the object in order to lift it.
What is the trade off of a pulley?
A pulley can trade off distance for force. By increasing the number of pulleys in a system, you can reduce the amount of force needed to lift an object in exchange for a longer distance over which the force must be applied.
What must be true when work is done?
When work is done, there must be a force acting on an object, and the object must move in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance the object moves in the direction of the force.
The amount of force that you must use on an object to lift it is?
Any force greater than its weight.
How do you find the minimum amount of force needed to lift an object?
The minimum amount of force needed to lift an object can be found by calculating the object's weight using the formula F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity. This force must be greater than or equal to the weight of the object to lift it off the ground.
What kind of force does a porter apply to lift an object?
A porter applies an upward force called the lifting force to lift an object. This force must be larger than the weight of the object to overcome gravity and lift it.
What is the force required to lift an object equal to?
The force required to lift an object is equal to the weight of the object, which is the mass of the object multiplied by the acceleration due to gravity (F = m * g). The force must overcome the gravitational force acting on the object in order to lift it.
What best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object

When work is done, there must be a force acting on an object, and the object must move in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance the object moves in the direction of the force.
How much work must be done to lift the beam 290m?
The amount of work done to lift an object is equal to the force applied multiplied by the distance over which the force is applied. Without information about the force or mechanism used to lift the beam, it is not possible to calculate the work done.
Which statements best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object
When An inclined plane makes work easier by increasing the distance decreasing the?
When an inclined plane is used, it increases the distance over which a force must be applied to move an object, thereby reducing the amount of force required to lift the object compared to lifting it straight up. This allows for the same amount of work to be done with less force, making the task easier.
What must occur for work to be done on an object?
Formally, energy is required to do work. Work is technically force times distance. Thus, what must occur is a force must be applied to an object and the object must move with some movement being in the direction of the force. The quantity of work done is the "dot" product of the force vector and displacement vector. To carry out work "on an object" or in any fashion requires the same amount of energy be used as the amount of work done. (Of course, friction and other inefficiencies result in the use of more energy than the actual work done, with the excess energy taking some other form, such as heat.)
What force is required to lift 100 pounds pds?
The force required to lift 100 pounds is approximately 100 pounds since the force needed to overcome gravity is equal to the weight of the object being lifted. This force, equivalent to the weight of the object, must be greater than or equal to the force of gravity acting on it.
