... object will accelerate. The product of the mass and acceleration of the object is equal to the resultant force. In equation form, this is represened as F = ma • A resultant force is 1 N if the acceleration it produces on a mass of 1 kg is 1 m s-2. • Newton’s Third Law of Motion states that for every ...

This means that forces always act in pairs. First an action occurs, such as two skateboarders pushing together. Then a r ...
