what is the difference between gravity and inertia?

The main difference between Inertia and Gravity is that the Inertia is a resistance of any physical object to any change in its state of motion and Gravity is a Curvature of spacetime attracting uneven distribution of masses together. Inertia is the resistance, of any physical object, to any change in its velocity.

The force of gravity is the force objects in space exerts on all other objects and is proportional to both the product of their respective masses and the square of the distance between them. The acceleration of gravity, you are actually supposed to put it as the “acceleration due to gravity”.

A g-force is a measure of acceleration. 1G is the acceleration we feel due to the force of gravity. It's what keeps our feet firmly planted on the ground. Gravity is measured in metres per second squared, or m/s2. On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2.

The basic difference between g and G is that 'g' is the Gravitational acceleration while 'G ' is the Gravitational constant. The value of g changes with altitude while the value of G remains constant.

Inertia is a force. Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia.

A static load has mass and potential energy while a dynamic load has mass and inertia because it is moving compared to your frame of reference. It takes much more force to change a mass's (which in Earth gravity as weight) rate of motion than it does to hold up the weight.

Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second. (Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s2.)

If we are comparing two different things to each other on Earth, they are pulled the same by gravity and so the one with more mass weighs more. But in space, where the pull of gravity is very small, something can have almost no weight. It still has matter in it, though, so it still has mass.

force = mass * acceleration. So inertia is proportional to mass and the relationship really comes down to the acceleration imparted on a mass by a force based on the above equation.

Inertial mass is a measure of how fast an object accelerates--given the same force, increasing the inertial mass implies decreasing acceleration. The simplest way to state the equivalence principle is this: inertial mass and gravitational mass are the same thing.

As nouns the difference between inert and inertia is that inert is (chemistry) a substance that does not react chemically while inertia is (physics|uncountable|or|countable) the property of a body that resists any change to its uniform motion; equivalent to its mass.

Gravitational mass is the charge to which gravity couples. Inertial mass is a measure of how fast an object accelerates--given the same force, increasing the inertial mass implies decreasing acceleration.

Centroid is the geometric centre of a body. On the other hand, centre of gravity is the point at which the whole mass of the body can be considered to be concentrated. Centre of gravity is the point at which a object can be suspended and be in perfect equilibrium.

Difference between gravity and gravitational force is that gravitational force describes the attractive force between any two masses while gravity specifically describes the resultant force with which an object is attracted towards the Earth.

Originally Answered: What is the difference between gravity and the acceleration due to gravity? Within Newtonian mechanics gravity is a force. In contrast, acceleration is change in velocity per unit time. Acceleration due to gravity is just that acceleration caused by gravity on a free body.

The tendency of an object to resist a change in velocity is known as the object's inertia. For example, a train has significantly more inertia than a skateboard. It is much harder to change the train's velocity than it is the skateboard's. The measure of an object's inertia is its mass.

Even though both the terms sound alike but there is a difference between gravitation and gravity, gravitation is the force occurring between two bodies whereas gravity is the force occurring between the earth and a body.
