1. From the time we wake up until we go to sleep, all our activities involve movement.
Motion will always be part of our daily life. When does motion takes place?
I.Motion takes place when unbalanced forces are applied to the object.
II.Motion takes place when an object changes its position.
III.Motion takes place when balanced forces are applied to an object
IV. Motion takes place when an object is at rest.
A only Bil only C. I and I D. II and IV
2. Which obiect does NOT demonstrate motion?
A Aball rolling on the floor
B. A ballerina dancing on the stage
C. Mother walking on the street
Pencil on the table
3. When do you say that an object has moved?
A.When the object is stationary
B. When the object changes its size
C. When the object has a lubricant
D.When the object changes its position in relation to a point of reference
4.While sitting on a wooden chair, you push a heavy table and your chair moves
backward. Which statement explains this?
A Objects in motion tend to remain in motion.
B. Objects at rest tend to remain at rest.
C. For every action, there is an equal and opposite reaction
D. Balanced forces acting on an object do not make the object move.

Answer:
1. What happens according to Newton if you let an untied balloon go?
3
rd Law
Air will rush out of the balloon forcing the balloon to move through the air in
the opposite direction, but equal in force.
2. Describe what happens if you are riding a skateboard and hit something (like
a curb) with the front wheels.
1
st Law
Your body will keep moving forward and fly off your skateboard since the
curb only stops the board, not yourself.
3. Describe what happens if you try and push Mr. Larson. What happens if he
pushes back?
2
nd Law
If you put force on Mr. Larson, force will be put back on you. Because of
Mr. Larson’s mass, you most likely will not have enough force to make him
accelerate. If Mr. Larson pushed you, you most likely would move in the
direction of the force since he has more mass.
4. Describe why you hold your gun next to your shoulder while deer hunting.
3
rd
Law
When you pull the gun’s trigger, it forces the bullet out of the gun, but at
the same time, the gun is forced in the opposite direction of the bullet
(towards you). Your shoulder is a new force that is introduced in order to
keep your gun from flying away from you.
5. What is another name for the first law of motion? Why is it given that
name?
Law of inertia.
It is given that name because inertia is the tendency of an object to resist
any change in its motion until an unbalanced force acts on it. That is the
same thing that Newton’s first law states.
6. Why should we wear seatbelts – use one of Newton’s Laws in your answer?
We should wear seatbelts so if we are in an accident our body doesn’t keep
moving at the same speed and in the same direction that the car was going.
A new force would be introduced to our bodies (the seatbelt) in order to
keep our bodies in place.
7. Using Newton’s laws explain why heavier objects require more force than
lighter objects to move or accelerate them?
2
nd Law
Something with more mass moving at the same acceleration as a lighter
object would require more force to change its speed or change its direction.
Our formula F=m x a is derived from Newton’s second law.
8. How can Newton’s laws be used to explain how rockets are launched into
space?
Newton’s third law would tell us that when the rocket pushes out fire with a
specific amount of force, the rocket will move in the opposite direction, but
with the same amount of force. This is what causes the rocket to shoot up
into the air.
9. Explain how each of Newton’s laws affects a game of Tug of War.
First Law: The rope will stay in the same place until the tugging starts (a new
force is introduced)
Second Law: We could measure a team’s force that they can pull the rope
with based on their body masses and the acceleration that they are causing
the rope to move at.
Third: 1 team pulls the rope towards themselves with a certain amount of
force and the opposing team is also putting force on the rope. The same
amount of force is applied from the ground to the people as they are putting
on the ground.
10. How do Newton’s laws affect your daily life?
Answers will vary, but EVERYTHING that happens in our lives can be
connected back to one of Newton’s 3 laws of motion since force is involved in
everything.
