Newton's Laws
Inertia is part of which Newton Law?
Newton's First Law
Can forces be added together?
Yes.
What are the two main categories of force?
Contact and Noncontact
What is acceleration?
Change in speed or direction.
True or False: The farther away the light source is from the object, the smaller the object's shadow.
True.
While playing kickball, I exert force on the ball. Does the ball exert force on me as well? Why or why not (using one of Newton's Laws)?
Yes, because Newton's Third Law says for every action there is an equal and opposite reaction.
What is the difference between balanced and unbalanced forces?
Balanced the forces cancel out, so nothing happens. Unbalanced forces causes change of movement of some sort.
Name an example of a contact force.
Friction or open to other answers
Gravity is pulling down on an object with 500 N. You are pushing up with 300 N. What is the total force on the rock with direction.
200N downward
Why might you plant a tree in the hottest part of your yard?
To create shade from it's shadow.
In bumper cars when I hit the car in front of me, they hit the car in front of them. Why?
Inertia.
The total of all forces acting on an object is known as
Net force.
In space, can things move without fuel? Why or why not.
Yes, because there isn't enough gravity to act upon the object.
Besides a strength, or magnitude, what does every force have?
Direction.
A flashlight and toy cars.
When I bowl, I bowl with a bowling ball and not a tennis ball. What law explains why we do this?
Two forces acting together in the same direction is known as:
Combined forces.

True or False: Gravity only acts on heavy objects.
False.
When the sun is low in the sky, early in the morning, trees form what type of shadow?
long shadows.
When playing basketball, when I dribble the ball it comes back up to me. What law explains this?
Newton's Third Law
True or False: If you are pushing a table, and your friend comes and pulls the table in the same direction, it'll move faster.
True.
Name the three types of non-contact forces.
Gravity, magnetism, and electric forces.

Open to answers.
Explain how shadows are formed.
