1. Non-contact force

2. Gravitational force

3. Frictional force

Explanation:

  • The most familiar non-contact force is gravity. The force of attraction that exists among all bodies that have mass.
  • One Newton approximately equals the force to lift vertically upwards a 100 g mass against the gravitational acceleration. Another commonly used unit of force is kgf, which is the force required to lift vertically upward a mass of 1 kg.
  • Frictional force offers the resistance to the applied force opposing its motion. Thus, it always acts in the direction opposite to that of the object in motion.
