WebFeb 9, 2024 · Gravitational constant (G) The value of g is 9.8m/s2. The value of G is. 6.67 x 10-11Nm2/Kg2. It is a vector quantity. It is a scalar quantity. The unit of g is m/s2. The value of G is Nm2/Kg2. Its value varies from place to place. WebMar 8, 2024 · Friction: When one surface is moving over another surface, a force which opposes the relative motion between the two is called friction. The force of friction always opposes the force applied to it. There will be no friction if there is no contact between the surfaces. Factors affecting friction
Friction - Meaning, Types and Laws of Friction - Vedantu
WebApr 10, 2024 · Here it is given that mass of the body m = 50Kg and coefficient of friction =0.3. The friction formula is given as. F = μN. Here N is the normal force given by the formula. N = mg. g is the acceleration due to gravity = 9.81 m/s2. So N = 50 × 9.81 = 5395.5. Kgm/s2 = 5395.5. WebAug 2, 2024 · Friction. Friction is that force which opposes the motion of two objects upon each other. Friction generates only when two objects are in contact with each other. When an object tries to move on other objects than an opposing force develops and resist this movement known as Friction. The friction force is likely to terminate the movement if … mod assy

Smoother surfaces exhibit less friction, rougher surfaces exhibit more friction. WebApr 6, 2024 · Friction may be classified into two main types as follows: Internal Friction It is the force that restricts motion between the elements constituting a solid material at the time of deformation. External Friction It happens when two bodies that are in contact with each other have the tendency to move, or they are in actual relative motion. inmate baton rouge
