Key Points
- Contact forces are forces that act on an object when it is in direct physical contact with another object.
- Non-contact forces are forces that act on an object without any physical contact.
- Examples of contact forces include tension force, normal force, frictional force, and air resistance.
- Examples of non-contact forces include gravitational force, electrostatic force, and magnetic force.
- Understanding the different types of forces is important in analyzing the behavior of objects in various situations.
Contact Forces
Contact forces are forces that act on an object when it is in direct physical contact with another object. Examples of contact forces include:
- Tension force
- Normal force
- Frictional force
- Air resistance
Non-Contact Forces
Non-contact forces are forces that act on an object without any physical contact. Examples of non-contact forces include:
- Gravitational force
- Electrostatic force
- Magnetic force
