Honors Physical Science : Review / Study Guide
Newton’s Laws: Chapter 2,3,4
Use your notes and textbook to define the following terms,
answer the question, or perform the problem. Bring a
calculator and a pencil for the exam! The more effort you
put into your study guide, the better prepared you will be
for the exam!
The formulas below will be given on the exam.
V=d/t
Weight (W) = mg
a= (vf-vi) / t
Fnet = W-R
F=ma
a=F/m
g = 10 m/s2
v=at
d=1/2at2
Chapter 2 : Motion P.16
1. Explain Aristotle’s idea of natural and unnatural motion.
2. What did Galileo learn from his “leaning tower of Pisa” experiment?
3. In Galileo’s Inclined plane experiment, He discovered If there is NO
_______________, then NO _____________ are required to keep an object in
motion.
4. An astronaut in outerspace away from frictional or gravitational forces throws a
rock. Explain the motion of the rock.
5. Instantaneous speed6. Constant speed7. Average speed8. What is the average speed of a cheetah that sprints 100m in 4 seconds?
9. What is the difference between speed and velocity? Write an example of an object
that has speed and one that has velocity.

10. Explain how a racecar speeding around a circular track can have constant speed
,but its velocity is changing.
11. Explain what is meant by the statement: Motion is relative. (IE : Are you Moving
right now relative to the Earth? Sun?)
12. Inertia13. Write Newton’s first law-
14. Give an example for Newton’s first law .
15. Force & net force16. Find the net force produced by a 30 N and a 20 N force in the following cases:
a. Both forces act in the same direction
b. Both forces act in opposite directions.
17. Vector quantity18. Draw two forces (as vector quantities) that are acting on a block that is suspended
by a rope and is attached to a spring scale. One force is gravity and is exerting a
force of 10N . The other force is the tension in the rope that is 10N.
19. In your drawing above, the block is at rest so net force on the block is
__________.
20. The  F = 0. Explain what this means.
21. You stand on a bathroom scale and it reads 110lbs. What would each scale read
read if you spread your weight evenly over 2 scales? ________
22.Explain how moving objects can be in a state of equilibriu

23. You are traveling in a car on a straight road at 150 km/hr . If you drop your cell
phone- in the car -where will it land?
Chapter 3 Newton’s Second Law of Motion-Force & Acceleration p.34
24. Acceleration25. Write three ways that an object can be accelerating.
26.Explain the relationship between acceleration and force.
27.If you push on a shopping cart it will accelerate.
a. If you apply four times the net force , how much greater will the
acceleration be?
b. If you apply ¼ the net force, how much less will the acceleration be?
28.When an object slows down, the object’s acceleration has a negative value. What
is the acceleration of a ball that is thrown upward with a speed of 36 m/s and then
reaches a speed of 0m/s after 3 seconds?
29.Mass
30.Inertia
31.Explain how mass and inertia are related.
32.Volume
33.Weight-
34.Calculate the Weight of a person who has a mass of 100kg on Earth.
35.Calculate the weight of a person who has a mass of 100kg on the moon
(acceleration due to gravity on the moon is 1.6 m/s2
36.Is your mass different if you are on the Earth or the Moon?
See other side
3
37.Does a 2 kg iron block have twice as much inertia as a 1kg block?
Twice as much mass?
Twice as much volume?
38.Explain the relationship between Mass and acceleration.
39.Suppose you apply the same amount of force to two carts,one cart with a mass
Of 4kg and the other with a mass of 8kg.
c. Which cart will accelerate more?
d. How much greater will the acceleration be?
40.Problem: A 2000 kg car is pulled by a cable with 4000 N of force. What is the
acceleration of the car?
41.What is the acceleration of a 40 kg block of cement when pulled sideways with a
net force of 200N?
42.Write Newton’s 2nd Law:
43.Friction44.Free fall45.Explain why objects in free fall (No air resistance –friction) fall at the same rate.
46.A rock dropped off a cliff picks up speed as it falls due to gravity. On earth the
acceleration due to gravity is ____________. After 4 seconds the rock will have a
speed of _________. Each second its speed will increase by ________.The rock will
have fallen a distance of _______________.
