Read each question carefully and provide the best answer based on your understanding of Newton's Second Law of Motion. Show all your work for calculation problems.
1. Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net acting on it and inversely proportional to its .
2. The formula for Newton's Second Law is F = .
3. The unit of force in the SI system is the .
1. Which of the following best describes Newton's Second Law of Motion?
An object at rest stays at rest.
For every action, there is an equal and opposite reaction.
Force equals mass times acceleration.
The total momentum of a system remains constant.
2. If you apply the same force to two objects of different masses, which object will have greater acceleration?
The object with less mass.
The object with greater mass.
Both objects will have the same acceleration.
Acceleration is not affected by mass.
1. A force of 50 N is applied to an object with a mass of 10 kg. Calculate the acceleration of the object.
2. An object accelerates at 5 m/s² when a net force of 20 N is applied. What is the mass of the object?
1. If the net force on an object is zero, its acceleration is also zero.
True
False
2. Increasing the mass of an object will increase its acceleration if the applied force remains constant.
True
False
