12) Consider the following statement: If an object has a non-zero net force acting on it during an interval, then its speed changes during the interval. (a) Is this statement valid? (b) If you contend the statement is valid, how do you know? (c) If you contend the statement is invalid, what is wrong with it? (d) If the statement is invalid, restate it to give a valid statement. (e) Is the valid statement (original, or your revision) a conditional or a bi-conditional? How do you know?
