# What is the relationship between distance and gravitational attraction?

## What is the relationship between distance and gravitational attraction?

Gravity and Distance The force of gravity is inversely related to the distance the alien is from Earth; this means that force of gravity decreases as the distance between the alien and Earth increases. As the distance between the alien and the surface of the planet increases, the force of gravity decreases.

What is the relationship between the strength of a gravitational force and mass?

The size of the gravitational force depends on the mass of the objects involved. The greater the mass, the greater the gravitational force. Furthermore, if the gravitational force is to be detectable on a human scale, then one of the objects must be as massive as a planet.

### What is the relationship between matter and gravity?

The more mass (matter) an object has, the more gravity it has. Weight is the measure of gravitational force acting on an object. This is why our weight would change on different planets”the planets are different sizes, so the strength of the force of gravity differs also.

What is the relationship between mass weight and gravity?

The mass of an object is the amount of matter it contains, regardless of its volume or any forces acting on it. Gravity is a force that attracts objects toward the Earth. The weight of the object is defined as the force caused by gravity on a mass.

Newton’s law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them.

What is the relationship between mass and acceleration?

Direct and Inverse Relationships The relationship between mass and acceleration is different. It is an inverse relationship. In an inverse relationship, when one variable increases, the other variable decreases. The greater the mass of an object, the less it will accelerate when a given force is applied.

## What are 3 examples of Newton’s second law?

What are Newton’s second law examples in everyday life?

What is the relationship between mass and inertia?

Mass is the quantity or measure of inertia in an object. The more mass found in an object, the more inertia it contains and therefore the greater its tendency to resist change.

### What’s the difference between mass and inertia?

Mass is a measure of the amount of matter in an object. Inertia is the resistance of a physical object to any change in its state of motion.

What is the relation between mass and inertia explain with example?

All objects resist changes in their state of motion. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Moment of Inertia: It is a measure of an object’s resistance to changes its state of rotation. Mass Moment of Inertia characterizes the angular acceleration undergone by a solid when subjected to a torque. Mass Moment of Inertia for a body depends on the body’s mass and the location of the mass.

What is second moment of inertia used for?

Area Moment of Inertia or Moment of Inertia for an Area ” also known as Second Moment of Area ” I, is a property of shape that is used to predict deflection, bending and stress in beams.

## How does mass affect moment of inertia?

It requires more efforts for larger mass to set up into the rotation. Thus, moment of inertia depends upon mass. Thus, it can be calculated that moment of inertia is dependent on the distance from the axis. If the mass is farther away from the axis, its moment of inertia is greater.

How do you calculate mass and inertia?

Translational Inertia = ma, where “m” is the mass, and “a” is the acceleration of the object. Calculate the rotational inertia or the moment of inertia by multiplying the mass of the object with square of the distance between the object and the axis, the radius of rotation.

### What are 2 ways an object can show inertia?

Types of Inertia (i.e. Dust particles stay at rest until you shake a carpet.) Inertia of motion ” An object will continue at the same speed until a force acts on it. (i.e. Body going forward when a car stops.) Inertia of direction ” An object will stay moving in the same direction unless a force acts on it.

Does inertia depend on speed?

No, inertia does not depend on speed. The more mass, the more inertia.

A more massive object has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects. An object would not have any inertia in a gravity-free environment (if there is such a place). Inertia is the tendency of all objects to resist motion and ultimately stop.

Is force needed to keep a moving body in motion?

An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. In the absence of any forces, no force is required to keep an object moving.

## When the car you are riding in stops suddenly you move forward because of?

You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest. You move forward because the car seat exerts an unbalanced force on your body.

What can impact a moment of inertia?

No. Torque depends on three factors: force magnitude, force direction, and point of application. Moment of inertia depends on both mass and its distribution relative to the axis of rotation.

### How do you stop inertia?

If you want to overcome inertia, you have to apply a force. A force will make something that is still start to move, like flicking a wad of paper with a pencil will make it move. Also force, due to resistance, will slow or stop something that is already moving.

What happens to inertia when speed is doubled?

There is no change in the inertia when the velocity is doubled. Inertia is dependent only on the mass of the object. When the velocity of the object increases the momentum will be doubled.
