What is the formula for potential energy in an object at a height h above the ground, where m is the mass of the object and g is the acceleration due to gravity?
The formula for potential energy in an object at a height h above the ground is PE mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height above the ground.
How is gravitational potential energy determined?
Potential Energy is calculated by the product of the mass of the object ( not weight! ), the gravitational acceleration ( 9.81 m/s/s ) and the height of the object above a datum. mass x 9.81 x height
Which factors much be known to calculate an objects gravitational potential energy?
To calculate an object's gravitational potential energy, you need to know the object's mass, the acceleration due to gravity, and the height at which the object is located above a reference point. The formula for gravitational potential energy is U = mgh, where U is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference point.
How gravitational potential energy determined?
Potential Energy is calculated by the product of the mass of the object ( not weight! ), the gravitational acceleration ( 9.81 m/s/s ) and the height of the object above a datum. mass x 9.81 x height
What properties of an object deterine its gravitational potential energy?
The properties of an object that determine its gravitational potential energy are its mass, the height above a reference point, and acceleration due to gravity. Gravitational potential energy increases as either the mass or the height of an object increases, or as the acceleration due to gravity increases.
What is above the line acceleration time graph?
An above the line acceleration time graph indicates that the object is experiencing positive acceleration, meaning its speed is increasing over time. The area above the time axis represents the magnitude of acceleration, while the duration of time corresponds to how long this acceleration is sustained. If the graph has a constant value, the acceleration is uniform; if it varies, the acceleration is changing. This type of graph is useful for analyzing motion and understanding how forces are acting on an object.

What is the acceleration of an object effected by gravity thrown at a 45 degree angle above the horiziontal at its highest point?
The only force acting on a projectile once launched is gravity. So the acceleration of any object launched at any angle is the acceleration due to gravity, -9.8m/s2.

What is the gravitational potential energy of an object equal to?
It is the product of the mass of the object in Kg, the gravitational acceleration which is 9.81 m/sec2, and the height of the object above earth's surface in meters. Result is in Joules

Gravitational potential energy increases as either the mass or the height of an object increases, or as the acceleration due to gravity increases.
What factors does the gravitational energy of an object depend on?
It depends on the mass of the object, the local value of acceleration of gravity, and the object's height above the elevation you're using for your zero-potential-energy reference level.
What is m g h?
mgh represents the potential energy of an object located at a height h above the ground, where m is the mass of the object, g is the acceleration due to gravity, and h is the height. It is calculated as the product of the mass, acceleration due to gravity, and the height.
How do photons exert force if force is mass times acceleration and photons have no rest mass and travel at constant speed?
The problem in the posed question is the "mass" in the equation you quote is the mass of the object upon which the force (whether it be a photon or not) is acting, NOT the mass of the object exerting the force. You can MEASURE the net force on an object with mass simply by measuring the acceleration of that object and dividing it by the object's mass. Or you can predict an acceleration of an object with mass by calculating what its net force will be, and then dividing that by the object's mass. Unrelated to the above excellent answer, but another comment on the question: You mention, correctly, that photons have no rest-mass. But the photon is never at rest, and at the speed at which it moves from place to place, it has mass.
What does gpe equal?
Gravitational potential energy (GPE) is the energy that an object possesses due to its position in a gravitational field. It is calculated as the product of the object's mass, the acceleration due to gravity, and the object's height above a reference point. Mathematically, GPE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height.
