Which of the following statements are true? Select all correct. Question 3 options: If an object speeds up, then the total work done on the object was positive. If an object moves at a constant speed, then the work done by each individual force is zero A force must be parallel to the displacement to do any work. If a force is perpendicular to displacement, it does zero work. If a force has a component in the opposite direction of the displacement, it does positive work. If an object doesn't move, then the work done by every individual force must be zero.
