Types of force

Forces that work on an object by touching it directly or through something else are called contact forces.

Examples:

• Muscular Force: This is the force used by our muscles or the muscles of animals like bullocks, horses, and camels to do work.
• Mechanical Force: The force created by machines to do tasks.
• Frictional Force: This force happens between two surfaces in contact. It slows down or stops the movement of one surface sliding over the other.

Forces that work on objects without touching them are called non-contact forces.

Examples:

• Gravitational Force: This force pulls objects toward the Earth, making them fall to the ground. An object's weight is due to this force pulling it toward the centre of the Earth.
• Electrostatic Force: A force that acts between objects with electric charges, even if they are not touching.
• Magnetic Force: The force a magnet uses to pull or push other magnets or metal objects from a distance. Since magnetic and electrostatic forces can act without direct contact, they are called non-contact forces.
