In physics, force is a push or pull acting upon an object as a result of its interaction with another object. It's a vector quantity, meaning it has both magnitude and direction. Forces can cause objects to accelerate, decelerate, or change direction. They're described using Newton's laws of motion. Here...

In physics, force is a push or pull acting upon an object as a result of its interaction with another object. It's a vector quantity, meaning it has both magnitude and direction. Forces can cause objects to accelerate, decelerate, or change direction. They're described using Newton's laws of motion. Here are some common types of forces: Gravity: A force of attraction between objects with mass. It's responsible for keeping planets in orbit around stars and objects on Earth's surface. Normal Force: The force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface. Friction: The force that opposes the motion of objects in contact with each other. It arises due to the roughness of surfaces. Tension: The force exerted by a string, cable, or any other type of flexible connector pulling on an object. Applied Force: A force applied to an object by a person or another object. Spring Force: The force exerted by a compressed or stretched spring when it's displaced from its equilibrium position. Electromagnetic Force: The force between electrically charged particles and magnets. It's responsible for phenomena such as magnetism and electricity. The unit of force is the Newton (N), named after Sir Isaac Newton. One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg m/s^2). read less
