What happens to the potential energy of water as gravity pulls the water downhill?
As water is pulled downhill by gravity, its potential energy decreases and kinetic energy increases. The potential energy is converted into kinetic energy as the water gains speed and momentum while flowing downhill.
How is the gravitational potential energy stored in an object converted into kinetic energy?
When an object falls due to gravity, its gravitational potential energy is converted into kinetic energy. As the object moves downward, the potential energy decreases, while the kinetic energy increases. This conversion happens due to the work done by the gravitational force on the object as it falls.
What are the energy transformations when an archer pulls the string on the bow and when the archer releases the bow?
When an archer pulls the string on the bow, mechanical energy from the archer's muscles is transformed into potential energy stored in the bent bow. When the archer releases the bow, the potential energy in the bow is converted back into kinetic energy of the arrow as it is propelled forward.
When a stone is kept on a table what energy it has?
The stone has potential energy due to its position above the ground. As gravity pulls the stone down, this potential energy is converted to kinetic energy.
What is the energy change that take place when going up in a lift?
An elevator going up is increasing its potential energy. This energy and some kinetic energy to speed up the elevator in its way up comes from an electric motor that pulls the lifting cables that hold the elevator.
What happens when gravitiy pulls water down a slope?
Both kinetic and potential energy vanish.
What happens to the potential energy of water as gravity pulls the water downhill?
As water is pulled downhill by gravity, its potential energy decreases and kinetic energy increases. The potential energy is converted into kinetic energy as the water gains speed and momentum while flowing downhill.
How is a river potential energy changed into kinetic energy?
As gravity pulls water down a slope, the water's potential energy changes to kinetic energy that can do work.
How is the gravitational potential energy stored in an object converted into kinetic energy?
When an object falls due to gravity, its gravitational potential energy is converted into kinetic energy. As the object moves downward, the potential energy decreases, while the kinetic energy increases. This conversion happens due to the work done by the gravitational force on the object as it falls.
What happens when gravity pulls water down a slope?
The water runs down hill. That's why all rivers lead to the sea.
What are the energy transformations when an archer pulls the string on the bow and when the archer releases the bow?
When an archer pulls the string on the bow, mechanical energy from the archer's muscles is transformed into potential energy stored in the bent bow. When the archer releases the bow, the potential energy in the bow is converted back into kinetic energy of the arrow as it is propelled forward.
When you climb a rope you change potential energy onto kinetic energy?
When you climb a rope, you are converting potential energy (stored energy due to the height you are above the ground) into kinetic energy (energy of motion as you climb downward). Gravity is helping you in this process as it pulls you downward while you climb.
When a stone is kept on a table what energy it has?
The stone has potential energy due to its position above the ground. As gravity pulls the stone down, this potential energy is converted to kinetic energy.
Why does a scater go faster when she pulles her arm into her body?
A spinning skater posses a certain amount of rotational kinetic energy. kinetic energy is generally considered the energy of motion. For a spinning object (the skater) the energy is given by the equation KE = 1/2 time the rotational moment of inertia, times the square of the rotational speed. The rotational moment of inertia is given as I = the mass of the object times the square of the object's radius. When the skater is spinning with arms outstretched, the "radius is some value, r out. As the skater pulls arms in, the "radius decreases. However, the rotational energy remains constant, so the rotational speed has to go up. Mathematically, the equations are KE = 1/2 Ir x w squared, where w is the rotational speed. Because the kinetic energy is constant, the equations become 1/2 mrout squared x wout squared =1/2 m r in squared x w in squared. the factor 1/2 and the mass m cancel, so the governing equation becomes r out squared x w out squared = r in squared x w in squared, or, simplifying, r out w out = r in w in. Solving for w in, w in = (r out w out)/r in. As r in decreases, w in increases.
What is the energy change that take place when going up in a lift?
An elevator going up is increasing its potential energy. This energy and some kinetic energy to speed up the elevator in its way up comes from an electric motor that pulls the lifting cables that hold the elevator.
What happens to the potential energy of the water in a river as gravity pulls the water downhill?
Since potential energy is proportional to elevation, the potential energy of water gets less and less as it goes downhill.Its kinetic energy (based on velocity) may well increase, but the question asked about potential energy.
What is the force that pulls an object away from the axis when it is in rotational motion?
it's centrifugal force..
