100
An object at rest stays at rest and an object in constant motion stays in constant motion until acted upon by an unbalanced force.
What is Newton's 1st Law of Motion?
100
A push or pull that acts on an object.
What is force?
100
When 20N of force pushes an object at rest to the left and 20N of force pushes the object to the right.
What object remains at rest / is a balanced or net zero force?
100
What will happen to the people on a bus if the bus stops suddenly?
They will fly forward.
200
For every action, there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
200
An object's tendency to resist a change in motion.
What is inertia?
200
When someone is pushing with 50N of force to the right and the other person is pushing with 10N of force to the left.
What is net force / acceleration to the right?
200
What would happen to a vase of flowers if you rapidly pulled the tablecloth from under them?
They would remain standing.
300
The heavier the mass of an object, the harder it is to move and/or stop the object from moving.
What is Newton's 2nd Law of Motion?
300
A force that acts against or opposes another force on an object.
What is friction?
300
If Spongebob was pushing a crabby patty to the left and plankton was pushing it to the right, which way would it go and why?
To the left, because Spongebob is bigger and stronger than plankton.
300
What happens to the speed of a little worm, if it is required to pull a large apple?
It goes slower.
400
This is another name for Newton's 1st Law.
What is Inertia / Law of Inertia?
400
A force that pulls objects to the Earth.
What is gravity?
400
If two people are pushing a box to the right and each person is putting forth 20N of force. Which way will the box move and with how much force will it be moving?
To the right with 40N worth of force.
400
What happens to the speed of a big worm, if it only has to pull a tiny apple?
It goes faster.
500
Newton's 3rd Law states equal in ______ and opposite in _______.
What is magnitude/force and direction?
500
When all forces on an object cancel each other out.
What are balanced forces / net force = 0N?
500
If Ms. Cibasek was pushing a box to the left and Mr. Abu-Rus was pushing a box to the right, which way would the box go?
To the right, because Mr. Abu-Rus is pushing with more strength and force than Ms. Cibasek (Ms. Cibasek is still awesome though!)
