What are the formulas potential energy and kinetic energy?

For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2.

What is the relationship between potential and kinetic energy on a roller coaster?

At the highest point on the roller coaster (assuming it has no velocity), the object has a maximum quantity of gravitational potential energy and no kinetic energy. As the object begins moving down to the bottom, its gravitational potential energy begins to decrease and the kinetic energy begins to increase.

How to talk about potential and kinetic energy?

Once we start walking, the potential energy is converted into kinetic energy. Draw a t-chart on the board, labeling one side Potential and one side Kinetic. Ask your students to give some examples of potential and kinetic energy, and list their responses on the board.

How long is kinetic energy in a video?

Description: Kinetic energy is the energy of motion, which is the subject of this explanatory this 4:48 minute video clip. The site’s infrastructure presents information with bright colors and animated action. The video animation is conceptually clear, well designed and developmentally appropriate for elementary school age children.

Which is the child with the least potential energy?

Her momentum is also the greatest. Child #1 has the least potential energy, zero. Child #3 has more potential energy than Child #2 (even though Child #2 appears to have more mass), because the center of mass of Child #3 is about four times further above the bottom of the arcs than that of Child #2.

How does a roller coaster change kinetic energy?

As the coaster cars go up and down the hills and around the loop of the track, a pie chart shows how energy is transformed back and forth between gravitational potential energy and kinetic energy. Clicking the play button on the video image on the homepage brings students to an interactive roller coaster video.
