FAMOUS SCIENTISTS
LAWS
VOCABULARY
SPEED, ACCELERATION, VELOCITY
100
The force of objects that are in close contact of each other and slows an object down.
What is friction?
100
He felt that objects do not fall at the same rate and that the heavier object will hit the ground first. He never tested his theory of falling objects
Who is Aristotle?
100
This law says that an object in motion wants to stay in motion and an object at rest, wants to stay at rest.
What is The First Law of Motion?
100
The amount of stuff/matter in something?
What is mass?
100
The distance gone is a certain about of time
What is speed?
200
The force that exists between magnets and the south and north pole of a magnet when they repel or attract each other.
What is magnetic?
200
He Felt that objects fall at the same rate. He tested his theory many times and found it to be true when the objects are the same shape
Who is Galileo?
200
This law states that an object at rest or in motion will not change its speed or direction unless something causes it to change.
What is The Second Law of Motion?
200
The tendency of an object at rest to stay at rest and an object in motion to stay in motion.
What is inertia?
200
The change in speed and direction
What is acceleration?
300
It is the force of an object pulling another object towards it.
What is gravity?
300
He was known for creating the Three Laws of Motion after an apple fell from a tree and hit him in the head
Who is Isaac Newton?
300
This law contains the concept of inertia?
What is The First Law of Motion?
300
A push or a pull.
What is a force?
300
The decrease in speed
What is deceleration?
400
The combination of one or more forces acting on an object.
What is net force?
400
He was born the same year Galileo died (1642) He was an inventor and invented the kite
Who is Isaac Newton?
400
This law states that for every action there is an opposite and equal reaction. Forces happen in pairs of an action force and a reaction force That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.
What is The Third Law of Motion?
400
When one or more forces are acting on an object and one force is stronger than the other, causes the object to change motion.
What is unbalanced force?
400
The speed and direction of an object
What is velocity?
500
If two forces of equal strength act on an object in opposite directions, the forces will cancel.
What is net force zero?
500
He was alive in the early 1600’s ( nearly 2,000 years after Aristotle)and died in 1642
Who is Galileo?
500
A chair is by the turtle tank. It stays there until the teacher picks it up and moves it across the room.
What is an example of The Second Law of Motion?
500
Forces on an object that does not require to touch the object.
What is a non-contact force?
500
The speed of an object that has traveled 30 miles in 2 minutes.
What is 15 miles per minute?
