Class of Forces
• Magnetic force, electrical force, gravitational force, and stretching of a spring are all different types of forces in physics.
Different Class of Force
• The different class of force is stretching of a spring.
Explanation
• Magnetic force is the force that is exerted by a magnet on a magnetic material. It is a non-contact force that can attract or repel magnetic materials.
• Electrical force is the force between two charged particles. Like magnetic force, it is also a non-contact force that can attract or repel charged particles.
• Gravitational force is the force of attraction between any two objects in the universe. It is the force that holds the planets in their orbits around the sun and keeps us on the ground.
• Stretching of a spring is a different type of force because it is a contact force that is exerted by a spring when it is stretched or compressed. When a spring is stretched or compressed, it exerts a force that is proportional to the distance it is stretched or compressed.
• Unlike the other types of forces, the stretching of a spring depends on the physical properties of the spring, such as its length, thickness, and the material it is made of.
Conclusion
• The different class of force is stretching of a spring because it is a contact force that is exerted by a spring when it is stretched or compressed.
