True/False Indicate whether the sentence or statement is true or false. 1. The inertia of mass is directly proportional to its velocity. 2. When a constant force is applied to an object,acceleration remains the same. 3. Action and reaction forces have the same direction. 4. When the force acting on an object is doubled, the effect on the acceleration of the object will be tripled. 5. When the normal force is doubled, the coefficient of friction is quadrupled acceleration than...
