Read each question carefully and answer to the best of your ability. Show your work for calculations.
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 = m × .
3. The unit of force is the , the unit of mass is the kilogram, and the unit of acceleration is meters per second squared.
4. If you apply a greater force to an object, what happens to its acceleration (assuming mass stays the same)?
It decreases
It increases
It stays the same
It becomes zero
5. Which of the following would have the greatest acceleration if the same force was applied to all of them?
A bowling ball
A car
A feather
A bicycle
6. A force of 10 N is applied to a 2 kg object. What is the acceleration of the object? (Show your work)
7. If an object has a mass of 5 kg and accelerates at 4 m/s², what is the net force acting on it? (Show your work)
8. A larger mass requires a smaller force to achieve the same acceleration.
True
False
9. Newton's Second Law only applies to objects moving at a constant velocity.
True
False
Match each term with its definition.
10. Force
a. The resistance of an object to changes in its state of motion
11. Mass
b. The rate at which an object changes its velocity
12. Acceleration
c. A push or a pull on an object
