A stone weighing 0.7 kilograms rolls down the inclined plane from position B to position A. Position A is located at sea level.

The difference in the gravitational potential energy of the ball between positions A and B is about joules. (Use PE = m × g × h, where g = 9.8 N/kg. )

Argon is adiabatically compressed from an initial volume of 16 liters to a final volume of 2 liters. by what factor do the following quantities change? do they increase or decrease? (a) the rms speed (b) the thermal energy of the gas (c) the molar specific heat cv (d) the pressure

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
