How can you calculate wasted energy from a falling object when given only height and mass?
Because gravitational potential energy is defined by g*m*h where g is the gravitational constant 9.8, m is mass, and h is height.
With just height and mass, you cannot calculate "wasted energy" by which i assume you mean energy lost to air resistance. However, if you are given the kinetic energy of the object just before it hits the ground, then you calculate the total energy before falling and compare it to the kinetic energy right before hitting the ground. the difference would represent the energy lost to air resistance

What kind of energy is in a falling object?
Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)
What is a drop height in physics?
In physics, drop height refers to the vertical distance an object falls under the influence of gravity. It is commonly used to calculate potential energy, kinetic energy, and impact force of a falling object. The higher the drop height, the greater the potential energy and impact force upon landing.
Does a falling object transfer energy?
Yes, a falling object transfers potential energy into kinetic energy as it descends due to gravity. The object's potential energy decreases as it loses height and gains speed, converting that potential energy into kinetic energy.
Does potentail energy have an influence on the final velocity of a falling object?
yes it does. u can calculate the final velocity of the falling object with the following eqn: initial potential energy= final kinetic energy or mgh = 1/2mv2 where m=mass, h = height,v=final velocity
What must be known in order to calculate the potential energy of an object?
To calculate the potential energy of an object, you need to know the object's mass, the acceleration due to gravity, and the height at which the object is located. The formula for potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

What is an example of potential energy into kentic energy?
An example of potential energy being converted into kinetic energy is when a rock is held up in the air and then released. As the rock falls, its potential energy due to its height is converted into kinetic energy as it gains speed.
What must be known in order to calculate the potential energy of an object?
To calculate the potential energy of an object, you need to know the object's mass, the acceleration due to gravity, and the height at which the object is located. The formula for potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.
How do you measure velocity of a falling object if height is 2m?
To measure the velocity of a falling object when the height is 2m, you can use the equation v=sqrt(2gh), where g is the acceleration due to gravity (approximately 9.81 m/s^2) and h is the height (2m). Plug in these values to calculate the velocity of the falling object when it reaches a height of 2m.
What variables influence the amount of potential energy a falling object has?
Mass of the object, height, and gravitational force. On Earth, Potential Energy = (mass) x (height) x (9.8 m/s)
What factors must be known to calculate an object gravitational potential energy?
its mass and height
Calculate the potential energy of a 5.00 kg object sitting on a 3.00 J of energy?
The potential energy of an object is given by the equation PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.81 m/s^2 on Earth), and h is the height of the object. Since no height is given, it's unclear how to calculate the potential energy in this case.
Why can an object have kinetic energy and potential energy?
Because they are not mutually exclusive. Take for example a falling object; while falling at a given velocity it has (.5)(mass)(velocity)2=Kinetic Energy but also has the potential energy of whatever distance it has yet to fall, which equals (mass)(gravity)(height)=Potential Energy These two types of energy equal the Total Energy of the falling object, which never changes as it falls.
How does height affect potential energy and kinetic energy?
Height directly affects gravitational potential energy, since this energy is equal to mgh (mass x gravity x height). Height does not affect kinetic energy, which depends on the speed, not on the height. Except indirectly - for example, if an object is falling down, its speed will usually increase.
