How do you calculate energy input for lifting objects by weight and height lifted?
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
What else can I help you with?
Why does the height affect the loop on a marble rollercoaster?
I would have gravitational potential energy, which is energy due to height.
How do you calculate the total pressure exerted on the base of a storage tank?
The Pressure is .434 times the height The FORCE takes a lot more calculations as the height and the weight of the water has to be calculated in plus the hydra-static pressure
How do you calculate the load bearing capacity of scaffolding?
Before you can calculate the load bearing capacity of a scaffold, you will need to know there are three types of scaffolding; light duty, medium duty, and heavy duty. Now you can calculate the load bearing capacity by using the height to base ratio.
What simple machine would you use to lift a piano to the top of a building?
To lift a piano to the top of a building, a pulley system would be the most effective simple machine. Pulleys can reduce the amount of force needed to lift heavy objects by distributing the weight and allowing for easier lifting with less effort. By using multiple pulleys in a block and tackle configuration, you can significantly decrease the force required to raise the piano safely to the desired height.
What is the formula to calculate pressure?
Force over Area= Pressure
How would you calculate an objects gravitational potential energy?
Multiply its weight by its height.
The increase in potential energy caused by lifting an object can be calculated by multiplying its weight by its change in height?
Yes, that's correct. The potential energy gained by lifting an object is directly proportional to the weight of the object and the height it is lifted. The formula to calculate this potential energy increase is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the change in height.
What is related to an objects height?
Gravitational potential energy
Does a job lifting heavy objects make you lose height?
No. It won't. Bones in your body are not going to compress under weight. But it is a known fact that you lose height during the day as the spine compresses. But, that height is regained in the night during sleep. A job lifting heavy objects will have other serious problems like back issues. So, losing height should be the least of your concern.
Potential energy dependent upon an objects weight and height?
weight times height
Describe the effect that height has on the force and energy needed to lift an object?
The force needed to lift an object is directly proportional to its weight, not its height. However, lifting an object at a greater height requires more energy due to the work done against gravity over a longer distance. So, height affects the energy required to lift an object but not the force needed.
Kinetic energy is related to an objects height true or false?
False. Kinetic energy is related to an object's motion or speed, not its height. Potential energy is related to an object's height, while kinetic energy is related to its motion.
Which factors much be known to calculate an objects gravitational potential energy?
To calculate an object's gravitational potential energy, you need to know the object's mass, the acceleration due to gravity, and the height at which the object is located above a reference point. The formula for gravitational potential energy is U = mgh, where U is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference point.
How do you calculate change in energy?
The change in potential energy is equal to mass*gravity*change in height
What 3 thing are necessary to calculate potiential energy?

The formula Weight x Height is used to calculate what kind of energy?
Relative gravitational potential energy.
