Highlight speedNormal
Force and acceleration are key concepts in physics that explain how objects move. Force is a push or pull acting on an object, while acceleration is the change in an object's velocity over time. According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that if you apply a greater force to an object, it will accelerate more. For example, if you push a toy car gently, it moves slowly, but if you push it harder, it speeds up quickly. The formula to remember is F = ma, where F is force, m is mass, and a is acceleration. This relationship helps us understand how different forces affect the motion of objects around us, from cars on a road to planets in space.
