They are falls caused by the environment like a slip and fall on ice or a loose rug. They are not falls caused by muscle weakness or a seizure etc.
It's either mechanical waves or water. Mechanical waves is what categeory it falls under, but water is an example of the medium.
It falls under physics along with gravity.
Example: a block of cheese has grown moldy. This is chemical spoilage. A block of cheese falls on the floor. This is mechanical spoilage.
Astronomers use the EM spectrum, Physicists speculate about it, yet the practical study of it falls to the Mechanical Engineers: your answer = mechanical engineering.
The mechanical energy of a coconut falling from a tree decreases. As the coconut falls, its potential energy (due to its height) is transformed into kinetic energy (due to its motion). Therefore, the total mechanical energy (potential energy + kinetic energy) decreases as the coconut falls.
In a paper spiral, energy is transferred in the form of mechanical energy as the paper spiral unwinds and falls due to gravity. This mechanical energy is converted into kinetic energy as the spiral moves.
Yes, high levels of mechanical energy can cause severe traumatic injuries that may result in death. For example, incidents such as car accidents or falls from great heights can impart significant mechanical energy to the body, leading to life-threatening injuries.
Yes, when you roll down a hill, you are converting potential energy (due to your position on the hill) into kinetic energy (due to your motion). This conversion of energy falls under the category of mechanical energy.
When a large rock falls from a cliff, it primarily demonstrates mechanical weathering. This process occurs as the rock breaks apart due to physical forces, such as impact with the ground or other rocks, without altering its chemical composition. Over time, further exposure to elements like wind, water, and temperature changes may lead to additional mechanical weathering, while chemical weathering would involve changes in the rock's minerals due to chemical reactions.
Mechanical energy can be transferred through the work performed by forces acting on an object, such as pushing or pulling. It can also be transformed from potential energy to kinetic energy or vice versa, for example, when an object falls or is lifted. Additionally, mechanical energy can be converted into other forms of energy like thermal or sound energy through interactions with the environment.
As the object falls, potential energy decreases while kinetic energy increases. The total mechanical energy (sum of potential and kinetic energy) remains constant in the absence of air resistance.
The mechanical energy of the ball is conserved as it falls freely in a vacuum, meaning the sum of its potential and kinetic energy remains constant. Additionally, the total momentum of the ball is conserved during its free fall.
