How can you calculate wasted energy from a falling object when given only height and mass?
Jeffjohnston1
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)
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
How do you calculate kinetic energy in a moving object?
2/ mass squared x height squared
What best describes the object's energy as it falls trough the air from the stationary position at height x?
The potential energy it had at height x when it was not moving is equal to the kinetic energy it will have as it is falling. Why? Law of the Conservation of Energy. Energy before will equal energy after.
What happens the the kinetic energy of a falling object?
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.

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 is an example of potential energy into kentic energy?
A falling object.A falling object.A falling object.A falling object.
What factors must be known to calculate an object gravitational potential energy?
its mass and height
How do you calculate kinetic energy in a moving object?
2/ mass squared x height squared
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.

Energy at a height is called what?
Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.
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.
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.
