Newton’s second law “ The acceleration of an object is directly proportional to the resultant force acting on it and inversely proportional to its mass. Newton's laws - Practice Exam Questions | SeeTheSolutions - Tailored tutorials. Estimate the net force needed to Known : You may know forces that are present without having force ever mentioned in the problem, and you may be asked for things like how fast an object moves in a circle or how much of an object is underwater. Newton’s 2nd Law Practice Assessment Part A 1. The mass of the dog and wagon together is 45 kg. ∑F = m a This law is a little easier to observe as compared to the first law… Newton’s second law of motion – problems and solutions Solved problems in Newton’s laws of motion – Newton’s second law of motion 1. From Newton's Second Law, F = ma, so the direction of the net force and resulting acceleration are in the same direction.
