Explanation:
Man-made: Global Warming
Natural: Grand Canyon
Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
Sedimentary, like sand.
Weathering and erosion make large rocks smaller.
