11.2 Questions Force and Mass Determine Acceleration 7. What formula is used to calculate acceleration? 1. What 3 concepts are involved in Newton’s second law? 8. A mass is 2kg. What other information do you need to calculate acceleration? 2. Look at the picture on page 354. What do the arrows in the diagrams show? 9. If an object moves at a constant speed, but it accelerates, what changes? 3. What happens to the acceleration of an object when the force on it increases? 10. How does the mass of an object affect its acceleration? 4. What is the standard unit of force? 11. Use Newton’s second law to determine how much force is being applied to an object that is traveling at a constant velocity. 5. What unit is used for mass when calculating force or acceleration? 6. If the same force is applied to two objects of different mass, which object will have the greater acceleration?
