what is friction
who is newton
what is gravity
Answers
Answer:
1) Friction is the force resisting the relative motion of solid surfaces fluid layers, and material elements sliding against each other.
2) Sir Isaac Newton PRS was an English mathematician, physicist, astronomer, theologian, and author who is widely recognized as one of the greatest mathematicians and most influential scientists of all time and as a key figure in the scientific revolution.
3) Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
Answer:
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
