Potential energy is defined as the energy possessed by a body due to its position or height above the surface of the Earth. Water stored in a dam has potential energy. This potential energy has the capacity to do work.Know More
When water falls from a height, its potential energy is used to rotate turbines that generate electricity. Any object falling from a height can cause damage on impact due its potential energy.
When an object is stationary at a height, it possesses potential energy only. When it moves downwards due to the gravitational pull of the Earth, some of the potential energy begins to transform into kinetic energy.
The formula for calculating potential energy is PE = mgh. In this equation, m refers to the mass of the body, g is the acceleration due to gravity, and h is the object's height above the Earth.
The international standard unit for measuring energy is the joule.Learn more about Motion & Mechanics
Motion is defined as the action of changing position or location. Motion, along with force and energy, are concepts relevant to mechanics, a subject of physics. Within mechanics, there is a more specific field of study called kinematics, and this is the most basic level of mechanics.Full Answer >
The path taken by a flying object in motion on the surface of the Earth is called a parabola. A parabola is a symmetrical arc, and the trajectory of flying objects with negligible air resistance in a gravitational field, as on the surface of the Earth, follows this path.Full Answer >
Geothermal energy is created at the center of the Earth, around 4,000 miles below the surface, through hot spots in plate boundaries. These hot spots contain more energy than all the gas and oil resources in the world and can be found underground and on the Earth's surface in the form of hot springs, volcanoes and geysers.Full Answer >
Motion can be thought of as a change in position from a specific reference point. Motion is a relational measurement, which means that an object cannot be said to be "in motion" without having a reference point to which it is moving towards or away from. The most common reference points to motion are objects that appear to be stationary on Earth's surface.Full Answer >
