Acceleration of Block against Friction Newton’s second law says that the acceleration (a) of an object is proportional to the force (F) applied on it, and the proportionality factor is the object’s mass (m). Force is a vector quantity, which means we must consider the direction in which it acts. Two main types of frictional Read more about Acceleration of Block against Friction[…]
Equation of a Plane in Normal Form and Cartesian Form Plane: A plane is a surface such that if any two points are taken on it, the line segment joining them lies completely on the surface. A plane is determined uniquely if. The normal to the plane and its distance from the origin is given, Read more about Equation of a Plane in Normal Form and Cartesian Form[…]
Stopping of Two Blocks due to Friction Friction is an opposing force that opposes the motion of one body over the surface of another body. Like in case of a ball freely rolling on the ground, the ball eventually comes to stop, because of the force of friction that acts between ball and the ground. Read more about Stopping of Two Blocks due to Friction[…]
