Read each question carefully and answer to the best of your ability. Show all your work for calculation problems. Remember Newton's Second Law: F = ma.
1. Newton's Second Law of Motion states that:
An object at rest stays at rest.
Force equals mass times acceleration.
For every action, there is an equal and opposite reaction.
Objects fall at the same rate regardless of mass.
2. If you apply the same force to two objects of different masses, which object will have greater acceleration?
The object with greater mass.
The object with smaller mass.
Both objects will have the same acceleration.
Acceleration is not related to mass.
3. The unit of force in the SI system is the .
4. According to Newton's Second Law, if the net force acting on an object is doubled, its acceleration will .
5. If the mass of an object is increased while the net force remains constant, the acceleration will .
6. A force of 50 N is applied to a 10 kg object. Calculate the acceleration of the object.
7. An object accelerates at 5 m/s² when a force of 100 N is applied. What is the mass of the object?
8. What force is required to accelerate a 20 kg bicycle at a rate of 1.5 m/s²?
9. Newton's Second Law applies only to objects in motion.
True
False
10. In the equation F = ma, 'a' represents average velocity.
True
False
11. Explain in your own words the relationship between force, mass, and acceleration as described by Newton's Second Law.
12. Describe a real-world example where Newton's Second Law is clearly demonstrated.
