PLEASE SUBMIT A MODEL OF THE POTENTIAL AND KINETIC ENERGY OF A ROLLER COASTER. I need a model of the instructions above and below.
Create a model to examine the potential and kinetic energy of a roller coaster cart.
BASICALLY, I NEED A PICTURE DRAWN OF THE POTENTIAL AND KINETIC ENERGY THAT A ROLLER COASTER HAS WHEN GOING DOWN A SLOPE.

Exit what is the density of an object having a mass of 5.0 g and a volume of 45.0 cm3?

What are some natural measures of time

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
