Force is defined as any push or pull that changes or tends to change the state of rest or uniform motion of an object. There are two types of forces: contact forces that require physical contact like muscular, frictional, and mechanical forces, and non-contact forces that act over a distance like magnetic, gravitational, and electrostatic forces.

1. Force
Any push or pull which changes or
tends to change the state of rest or of
uniform motion,due shape or size of
the body is called force

2. Types of Forces
1. Contact Forces
2. Non-Contact Forces

3. Contact Forces
• Muscular Force
• Frictional Force
• Mechanical Force

4. Non-Contact Forces
• Magnetic Force
• Gravitational force
• Electrostatic Force
