What is Newton's first law of motion?
Newton's first law of motion states 'an object will only experience acceleration if a resultant force is acting on it'. This means that only unbalanced forces will cause a change in the speed of the object. For example if equal forces act on the object in opposite directions they will cancel each other out, meaning there is no resultant force and no acceleration.
