What is the gravitational potential energy of a 2 kg vase resting on a shelf 3 meters high?
Gravitational potential energy is given by Ep=mgh and in this case the gravitational potential is simply 3⋅g or about 29.4J .
What is the potential energy of 2 kg?
The potential energy of a body of mass 2kg raised to a height of 2m is 40J.
How much potential energy is gained by a 2 kg book when it is waste 1.5 m above the table?
The basic equation is also the working equation ∆PE = mgh ∆PE = (2 kg)(9.8 m/s2 )(1.5 m) = 29.4 joules Example 2 A book with mass of 1.5 kg on a table that is 1.2 m high is raised onto a shelf. The shelf is 2 m from the table top. a) What is the gravitational potential energy of the book relative to the table top?
What is the gravitational potential energy of a 10kg book that is placed on a shelf that is 2.5 m high?
Example: What is the Gravitational potential energy of a 10kg book that is placed on a shelf that is 2.5m high? Exp = (10)(9.8)(2.5) = 245J Page 2 Name: Worksheet: Emk & EGP Use the motional kinetic energy and gravitational potential energy formulas to answer the following questions – Be sure to use 3 Step Math!!! 4.
What is g in gravitational potential energy?
g = acceleration due to gravity. h = height of the object.
What is g in gravitational potential?
Mathematical form. The gravitational potential V at a distance x from a point mass of mass M can be defined as the work W that needs to be done by an external agent to bring a unit mass in from infinity to that point: where G is the gravitational constant, and F is the gravitational force.
What is the potential energy of a body of mass 250 kg is at a height of 30 meter?
Answer: 7500 is the answer of this question….
What is the relationship between gravity and potential energy?
Gravitational potential energy is one type of potential energy and is equal to the product of the object’s mass (m), the acceleration caused by gravity (g), and the object’s height (h) as distance from the surface of the ground (the body).
How many joules of potential energy does a 3kg object have?
In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth’s gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s 2 * 5m = 147.15 J. 9.81 meters per second squared (or more accurately 9.80665 m/s 2) is widely accepted among scientists as a working average value for Earth’s gravitational pull.
What is the gravitational pull of Earth’s gravity?
9.81 meters per second squared (or more accurately 9.80665 m/s 2) is widely accepted among scientists as a working average value for Earth’s gravitational pull. This figure is based on a measure of gravity at sea level at a latitude of 45°.
