The equation for an object's potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.
In a baseball game, the ball has the most potential energy when it reaches its highest point. This is because at the highest point, the ball has the maximum height and therefore the maximum potential energy.
To calculate the potential energy of the water tank on the roof of an apartment building, we can use the equation PE = mgh. Given that the mass of the water tank is 38,000 kilograms and the height is 58 meters, we can substitute these values into the equation as follows:
PE = (38,000 kg) * (9.8 m/s^2) * (58 m) = 211,672,160 J
An object's potential energy is determined by its mass, gravity, and height. The statement "The object's mass, gravity, and height determine its potential energy" best describes an object's potential energy.
To explore potential energy using collaborative learning, members of a team can work together to create a plan, and then choose different tasks to carry out the plan. This allows the team to collaborate and explore potential energy through different perspectives and approaches.
