The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
What is the force of attraction?
a force between two bodies, molecules, particles, or the like, that attracts each to the other. … Gravity is the force of attraction between two bodies that have mass.
How do you find the force of attraction in physics?
Answer: To get the attraction force between these masses we use the above equation, where m1 = 800 kg, m2 = 500 kg, d = 3 m. F = 2.964*10–6 N. 2) At what distance are two masses of 60 kg and 70 kg, if the magnitude of the force with which they are attracted is 9*10–4 N?
What is attractive force in physics?
Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.
How do you calculate attraction?
Calculate the force of attraction according to F = k * q1 * q2 / d2.
Why there is force of attraction?
The attraction occurs when two objects of opposite charge are in close proximity, and the electrical force causes these objects to attract. Therefore, positive and negative charges will attract each other.
What is the force of attraction or repulsion?
Attraction is a force between two or more dissimilar or unlike charges. Two charges of dissimilar characteristics pull towards each other. Repulsion is a force between two or more similar or like charges. Two charges of similar characteristics pull away from each other.
What is vanderwall force of attraction?
van der Waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids. … The tendency of such permanent dipoles to align with each other results in a net attractive force.
Which of the following is correct order of forces of attraction?
The forces of attraction are the strongest in solids, followed by liquids and the weakest in gases. Oxygen is a gas, water is a liquid and sugar is a crystalline solid. So the increasing order of forces of attraction is Oxygen What is gravitational attraction?
Definitions of gravitational attraction. (physics) the force of attraction between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface. synonyms: gravitation, gravitational force, gravity.
What is value of g in physics?
In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.
