Gravitational force attracts every massive particle to every other massive particle. It does so by altering the space between the objects, where each particle causes a small gravitational well. Frictional force is caused by the intermolecular attraction between two very close objects.
The main difference between these two forces is their dependence on distance between the objects. Gravitational force is inversely proportional to the square of the distance, classifying it as a long distance force. Conversely, frictional force depends mostly on London Dispersion/ forces, which has a magnitude that is inversely proportional to the distance to the sixth power. This is more clear in the equations modeling these two interactions:
FG=Gm1m2/r2 FL=k/r6
Where FG is the force of gravity and FL is the London force
G is the gravitational constant (6.674x10-11N(m/kg)2)
m1, m2 are the masses of the respective massive bodies
r is the distance between the respective bodies
k is a constant that depends on the polarizability and the ionization energies of the two bodies (in normal conditions other factors would have to be considered in this constant, but for an approximation this is sufficient).
Frictional force, unlike gravitational force, can be changed by the application of an external force perpendicular to the direction of the frictional force. Frictional force experienced by an object is equal to the product of the coefficient of friction (influenced by FL, shown above) and the normal force. Therefore, by changing the normal force (defined at the contact force perpendicular to the surface on contact, it keeps the object from falling through the surface) the frictional force can be changed. An intuitive example is moving a couch: the frictional force is much greater when there is someone sitting on it, increasing the normal force.
What else can I help you with?
Difference between electric forces and gravitational forces is that electrical forces include?
In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.
What is a naturally occurring force related to two bodies in motion?
Gravitational force is a naturally occurring force related to two bodies in motion. It is the attraction between objects with mass and is responsible for keeping planets in orbit around the sun and objects on Earth's surface.
What is the gravitational force between the Earth and your body called?
Your weight. Weight is the definition of the force between the earth and other objects. Thus you weight is the gravitational force acting on you from the earth.
Can yiu give you 3 situations where frictional force is applied?
Walking on a rough surface: When you walk on a surface like gravel or sand, the frictional force between your shoes and the ground helps you maintain traction and prevents slipping. Braking a car: When you apply the brakes in a car, the frictional force between the brake pads and the wheels slows down the vehicle by converting kinetic energy into thermal energy. Writing with a pen: When you write with a pen on paper, the frictional force between the pen tip and the paper surface allows the ink to transfer onto the paper.
Explain how mass and the distance of an object from other objects affect its gravitational force?
The gravitational force between two objects is directly proportional to the mass of the objects. The greater the mass of the objects, the stronger the gravitational force between them. Additionally, the gravitational force between two objects is inversely proportional to the square of the distance between their centers. As the distance between objects increases, the gravitational force between them decreases.
2 kinds of forces?
Gravitational force, which is the force of attraction between two masses, and electromagnetic force, which is the force between electrically charged particles.
You push the ball with force of 22.8N which induces a -2.3N frictional force. what is the net force while you push the ball?
The net force is the difference between the applied force and the frictional force: 22.8N - 2.3N = 20.5N.
At what height in kilometers above the surface of the Earth is there a 4 percent difference between the approximate gravitational force mg and the actual gravitational force on an object?
At what height in kilometers above the surface of the Earth is there a 4% difference between the approximate gravitational force mg and the actual gravitational force on an object
Write the forces which are acting on aircraft during flying?
Gravitational force,Frictional force of air..........
What are ten different forces?
Gravitational force Electromagnetic force Strong nuclear force Weak nuclear force Frictional force Tension force Spring force Magnetic force Electric force Buoyant force
What is non frictional force?
Non-frictional force refers to forces that act on an object without involving any friction between surfaces. Examples include gravitational force, electromagnetic force, and normal force. These forces can cause motion, deformation, or other effects on an object without the need for friction between surfaces.
What is the 3 net force of a car rolling down a ramp?
The net force acting on a car rolling down a ramp is the result of the gravitational force pulling it downwards and any frictional forces resisting its motion. Generally, the net force will be equal to the component of the gravitational force parallel to the ramp minus the frictional force.
What does the frictional force vs normal force graph reveal about the relationship between these two forces?
The frictional force vs normal force graph shows that there is a linear relationship between the two forces. As the normal force increases, the frictional force also increases proportionally. This indicates that the frictional force is directly proportional to the normal force.
What frictional force?
Frictional force is the force that opposes motion between two surfaces.
What is the force that oppose motion between surface?
Frictional force
In which direction does frictional force act?
Frictional force always acts in the opposite direction to the relative motion between two surfaces in contact. If there is no relative motion, the frictional force resists the impending motion between the surfaces.
What are the Five main types of forces?
The five main types of forces are gravitational force, electromagnetic force, weak nuclear force, strong nuclear force, and frictional force. These forces govern the interactions between objects and particles in the universe.
