The two basic types of forces are contact forces ( ex. friction, tension in a string, air resistance) and non-contact forces (ex. gravitational, magnetic forces).

If no net force acts on an object, it will either remain at rest or continue to move at a constant velocity (uniform motion).

They provide clear, step-by-step detailed solutions for complex questions which are in the NCERT Textbook. By regularly solving these exercises, students can evaluate their understanding, identify areas for improvement, and build confidence in mastering the subject.
