Forces

Forces interact to influence the motion of objects in everyday life. When multiple forces act on an object, they can combine to make it move faster, s

Gravity is a fundamental force that pulls objects toward one another. It is why objects fall to the ground and planets orbit the Sun. The strength of

Isaac Newton’s Law of Universal Gravitation explains that every object in the universe pulls on every other object with a force called gravity. The st

Einstein’s theory of gravity, also known as the General Theory of Relativity, changed how we understand gravity. Instead of seeing gravity as just a p

Acceleration due to gravity is the rate at which objects speed up as they fall toward the Earth. Gravity pulls objects down at about 9.8 meters per se

Orbital motion refers to the movement of an object around another object due to gravitational attraction. This motion occurs in space, where planets o

Friction is a force that resists motion between two surfaces in contact. It plays a crucial role in natural and engineered systems, helping objects st

Friction is a force that resists motion when two surfaces are in contact. It influences how objects start moving, keep moving, or stop. Solid objects

Forces are pushes or pulls that can cause objects to move, stop, or change direction. Some forces need direct contact between objects to work, while o

Friction is the force that resists motion between two surfaces that are touching. You feel it every day—when you walk, hold a pencil, or slow down a m

Friction is a force that resists motion when two surfaces touch. While friction is helpful in many cases—like keeping you from slipping—it can also sl

Fluid friction is the resistance that occurs when an object moves through a liquid or gas. You experience it when swimming in water or feeling the air

Fluid friction, also called drag or air resistance, is a type of friction that acts on objects moving through liquids or gases. This force slows down
