Answer:
Thermal energy typically flows from a warmer material to a cooler material. Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation.
Explanation:
ion know...
For the gravitational force the formula<span> is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s</span>2<span> at the surface of the earth) and h is the </span>height<span> in meters. Notice that gravitational potential </span>energy<span> has the same units as </span>kinetic energy, kg m2<span> / s</span>2<span>.

Answer:
Point A (Maximum height)
Explanation:
Potential energy is given as the product of mass, height and acceleration due to gravity hence expressed as mgh where m is the mass of roller coaster, h is the height and g is acceleration due to gravity. Since the mass and g are constant for a roller coaster, the main factor that will influence the magnitude of energy is the height. The higher the height, the higher the potential energy and vice versa. Using the attached image, the highest point is point A
