question : a 10 kg body is allowed to freefall from rest from a height of 10 m, what will be its velocity ?
assume g = 10 (m/s)/s
the potential energy lost will = kinetic energy gained
mgh = 10*10*10 = 1000 joules
velocity after fall = sq root (2*g*s) = 14.14 m/s
ke = 0.5*m*v^2 = 0.5*10*200 = 1000 joules
What else can I help you with?
What is an example of gravitational energy transforming to mechanical energy?
Gravitational potential energy IS mechanical energy. Mechanical energy includes both kinetic energy, and potential energy.When an object falls, gravitational potential energy will be converted to KINETIC energy.
Can an objects mechanical energy be equal to its gravitational potential energy?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
Can a objects mechanical energy be equal to its gravitational potential energy?
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.
Can an objects mechanical energy be equal to its gravitational potential energy explain?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
What type of energy converts into mechanical energy?
Potential energy (such as gravitational potential energy or elastic potential energy) can be converted into mechanical energy when an object is in motion, either through the force of gravity or by releasing stored energy.
Is a windmill gravitational energy?
no -- the windmill converts the kinetic energy from wind to electrical energy. Gravitational energy is another term for potential energy.
Can objects mechanical energy be equal to its gravitational potential energy?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
What terms is synonymous with potential energy?
Gravitational potential energy, mechanical energy.
Which of the following is a form of mechanical energy.A.internal energy B.Chemical potential energy C.Gravitational potential energy D.electrical energy?
Gravitational potential energy is a form of mechanical energy. It refers to the energy stored in an object based on its position relative to a reference point in a gravitational field.
The mechanical energy of a coconut falling from a tree A. gravitational potential energy B. Chemical potential enregy C. thermal energy D. mechnaical energy?
A. gravitational potential energy. When the coconut is still in the tree, it has stored potential energy due to its position in the Earth's gravitational field. This potential energy is converted to kinetic energy as the coconut falls, which is a form of mechanical energy.
What is mechanial energy?
can an object's mechanical energy be equal to its gravitational potential energy
A pendulum has a kinetic energy of 65 J and a gravitational potential energy of 78 J. What is its mechanical energy?
The mechanical energy is the sum of the two.
