What is the GPE of a 20kg mass 15m high?
The gravitational potential energy (GPE) of a 20kg mass 15m high can be calculated using the equation GPE = mgh, where m is the mass (20kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (15m). Plugging in these values, the GPE would be approximately 2943 Joules.
What is an example of an object that can make both KE and GPE?
A roller coaster is an example of an object that can have both kinetic energy (KE) and gravitational potential energy (GPE) as it moves along its track. At the top of a hill, the roller coaster has high GPE due to its height, and as it moves down the hill, the GPE is converted to KE, giving it speed and kinetic energy.
What is the GPE of a ball?
The gravitational potential energy (GPE) of a ball depends on its mass, height above the reference point, and the acceleration due to gravity. The formula to calculate GPE is GPE = mass x gravity x height.
What is the GPE of a coffee mug with a mass of o.3 kg on a 1 m high counter top?
The gravitational potential energy (GPE) of the coffee mug can be calculated using the formula: GPE = mgh, where m is the mass (0.3 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (1 m). Therefore, GPE = 0.3 kg * 9.81 m/s^2 * 1 m = 2.943 J.
How do you convert GPE into joules?
To convert gravitational potential energy (GPE) to joules, you can use the formula: GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity in meters per second squared, and h is the height in meters. Calculate the GPE using this formula to get the energy in joules.
