What is the difference between gravitational force gravitational potential and gravitational potential energy?

Gravitational force is an attractive force that apperas between any two masses. Gravitational force is a force which means that it changes the motion of an object. Gravitational potential energy is the amount of energy a mass [apple] possesses due to its positions in the gravitational field.

What is the difference between gravitational force and gravitational field strength?

Gravitational field strength is the force experienced by a unit mass. Gravitational force is the amount of force acting on a body. It is the product of field strength times the mass under consideration.

What is the relationship between gravitational potential energy and gravitational field strength?

g=GMr2 where g is the gravitational field strength at a point which is r meters away from a point mass. ϕ=−GMr where ϕ is the gravitational potential at a point which is also r meters away from a point mass.

What’s the difference between potential energy and gravitational potential energy?

Potential energy is energy that is stored in an object or substance. Gravitational potential energy is energy in an object that is held in a vertical position.

What is the difference between gravitational potential energy and elastic potential energy and give the example of each?

Example: (i) Gravitational potential energy – A book kept on a table possesses gravitational potential energy because of its position above the ground. (ii) Elastic potential energy – The stretched rubber string of a catapult possesses elastic potential energy because of the change in shape of the string.

What is the difference between elastic energy and elastic potential energy?

Definition: Gravitational potential energy is the energy that an object has due to its position in a gravitational field. Elastic Potential Energy is the energy that a material gains after undergoing deformation.

What is the difference between gravitational potential and kinetic energy How is the total mechanical energy computed?

The Total Mechanical Energy As already mentioned, the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.

Is gravitational potential energy greater than elastic potential energy?

Gravitational potential energy depends on an object’s weight and its height above the ground (GPE = weight x height). Elastic potential energy is due to an object’s shape. It results when an elastic object is stretched or compressed. The more it is stretched or compressed, the greater its elastic potential energy is.

Is gravitational potential or kinetic energy?

Gravitational energy or gravitational potential energy is the potential energy a massive object has in relation to another massive object due to gravity. It is the potential energy associated with the gravitational field, which is released (converted into kinetic energy) when the objects fall towards each other.

What is the difference between gravitational potential energy and gravitational potential?

Gravitational potential concerns with moving a unit mass. Whereas, gravitational potential energy is defined as the amount of work done in moving a given mass (not unity but a mass ‘m’) from that point to infinity against the effect of gravitational field. r = distance between the bodies.

What is the relationship between gravity force and gravity field strength?

Gravitational force: the force that two objects exert on one another due to gravitational energy. Gravitational field strength: a measurement of the force of gravity at a specific distance from the source. By convention, a 1 kg weight is used in the calculation.

What determines the direction of motion in a gravitational field?

Gravitational potential determines the direction of motion of a body in the gravitational field of another body. Gravitational potential energy of a particle at a point in a gravitational field due to a body is measured by the work done in moving the particle from infinity to that point.

Why is the gravitational potential at infinity always negative?

The gravitational potential at a point is defined as the amount of work done on a unit mass when bringing it from infinity to the given point. Since the gravitational potential at infinity is zero and the amount of work to be done is negative, the gravitational potential is always negative.
