How much energy do you end up with if there is fifty joules of potential energy?
Not sure what you mean. 50 J = 50 J.
What has more potential energy a 50 kilogram stone or a 70 kilogram stone?
Both of them equal energy. Potential energy = mgh = 100*9.8*1 and 50*9.8*2 are equal.
If the potential energy of a swing is 200 J at its highest point and 50 J at its lowest point what is the kinetic energy of the swing at its lowest point if mechanical energy is conserved?
150J, as the potential energy has been converted to kinetic energy as the swing accelerates downwards (and forwards) from the top of its swing. Therefore the decrease in potential energy corresponds directly to the increase in kinetic energy if we are ignoring things like friction. So KE = 200-50= 150
Which has more gravitational potential energy a 50-kg stone or a 70-kg stone?
70kg
What is the two main forms of energy?
Kinetic energy (energy of motion) and potential energy (stored energy) A ball at the top of a building getting ready to be dropped has potential energy, but a ball falling has kinetic energy If the ball is at the top of the building, it has 100% potential and 0% kinetic and when it is halfway from top to bottom and falling it has 50% of each
What is the potential energy given to the 50.0 kg hammer of a pile driver when it is raised 4.00m?
P.E. = M G H = (50) x (9.8) x (4) = 1,960 joules

Will an object have more potential energy atop a 50 foot hill or 100 foot hill?
An object will have more potential energy at the top of a 100 foot hill. Gravitational potential energy is directly proportional to height.
How much Potential energy does a guitar string have that is 50 cm in length with a tension of 50N and displaced 0.8 m at its midpoint?
It's 128 Joules. PE (Potential Energy) = 2(50 N) divided by .50 meters. Multiply that all by (.8m)2

Calculate the change in potential energy of 8 million kg of water dropping 50 m over Niagara Falls?
Potential energy = m g h = (8 x 106) (9.8) (50) = 3.92 x 109 joules
How can kinetic energy turn into potential energy?
The conversion of kinetic energy into potential energy (and vice versa) is a fundamental concept in physics and is often associated with the principles of mechanical energy conservation. The relationship between kinetic and potential energy is governed by the law of conservation of energy. Gravitational Potential Energy: Gravitational Potential Energy:ENTER FOR $1000 🤑 CASH FOR SUMMER 🌞MER 🌞 One common example involves the conversion of kinetic energy to gravitational potential energy and vice versa. Consider an object in free fall near the Earth's surface. As the object falls, it loses kinetic energy and gains gravitational potential energy. Conversely, if the object is lifted against gravity, it gains potential energy and loses kinetic energy. Spring Potential Energy: Another example involves the conversion of kinetic energy to elastic potential energy and vice versa. When a spring is compressed or stretched, it stores potential energy in the form of elastic potential energy. As the spring is released, this potential energy is converted into kinetic energy. The mathematical expressions for these relationships are as follows: Gravitational Potential Energy (U) and Kinetic Energy (K): For an object of mass (m) at height (h) above the ground: � = � � ℎ U=mgh � = 1 2 � � 2 K= 2 1 mv 2 where � g is the acceleration due to gravity, and � v is the velocity of the object. The total mechanical energy (E) is the sum of kinetic and potential energy and remains constant in the absence of external forces (ignoring air resistance and other non-conservative forces): � = � � E=U+K Elastic Potential Energy (PE) and Kinetic Energy (K): For an object attached to a spring with a spring constant (k) and displacement (x) from equilibrium: � � = 1 2 � � 2 PE= 2 1 kx 2 � = 1 2 � � 2 K= 2 1 mv 2 Again, the total mechanical energy is conserved in the absence of non-conservative forces. In summary, the conversion between kinetic and potential energy depends on the specific forces at play (gravity, spring forces, etc.) and is governed by the law of conservation of energy. The total mechanical energy of a system remains constant in the absence of non-conservative forces.

What is the gravitational potential energy to a car that is 1500kg and is dropped from 50 meters?
After the car is dropped, it has NO gravitational potential energy.Before it's dropped, you can calculate the potential energy as mgh (mass x gravity x height). You can use 9.8 for gravity.
