Force and motion are two fundamental concepts in physics. Force is a push or pull on an object that causes it to change its position or motion. Motion is the movement of an object from one place to another.
Some common examples of simple force and motion problems include a ball rolling down a ramp, a person pushing a shopping cart, or a car accelerating from a stop sign.
Force is calculated by multiplying an object's mass by its acceleration, as described by Newton's second law: F=ma. Motion can be calculated using the equations of motion, such as s=ut+0.5at^2 for constant acceleration.
Speed is the rate at which an object moves, while velocity is the rate at which an object moves in a specific direction. Speed is a scalar quantity, while velocity is a vector quantity.
External factors such as friction, air resistance, and gravity can affect the force and motion of an object. These forces can either increase or decrease the object's speed or change its direction of motion.
