Since mass, or inertia, is an object’s resistance
to change, when the mass of an object in increased, it’s acceleration will decrease since it will have a greater resistance to change. When the car had more weight added to it, it's acceleration decreased since an object with a larger mass needs a stronger force acting upon it for it to be moved at the same acceleration as an object with smaller mass. Because of this, when the ramp angle in the experiment was adjusted and more force was being put on the car with the mass at a constant for each of the three measures for each angle, the acceleration decreased as the force and mass were increased. So, when the force measured at each angle is divided by the mass of the car, the values form a positive slope.
An object with a larger mass needs a stronger force to be moved at the same acceleration as an object with smaller mass. Newton’s second law of Motion ^^^ Mass- resistance to change/inertia Acceleration - change Force - a push or pull on an object The acceleration of an object is determined by two forces, mass and acceleration) As force acting upon an object is increased, the acceleration of the object is increased) As the mass of the object is increased, the acceleration decrease
