The scientist that developed the laws of energy by the age of 23.
What is Sir Isaac Newton
100
Any push or pull that causes an object to move, stop or change direction.
What is a force?
100
Something that makes work seem easier by changing the size and direction of a force.
What is a machine?
100
The variable can be the only thing that changes if you want to have this type of experiment.
What is a valid experiment?
200
The energy of motion is this.
What is kinetic energy?
200
Newtons 1st law of motion.
What is an object at rest will stay at rest and an object in motion will stay in motion unless acted on by another force.
200
A force that acts against motion when two surfaces rub against eachother.
What is friction
200
A type of machine that could help a kid get his things into a tall tree house.
What is a pulley?
200
The variable that changed in the Falling Weights Experiment.
What is the weight was changed when a washer was added to the paper clip?
300
The energy that an object has because of where it is or because of its condition is called this.
What is potential energy?
300
Newton's 2nd Law of Motion
What is an object's acceleration depends on its mass and the size and direction of the force acting on it.
300
The force that pulls all objects in the universe toward one another.
What is gravity?
300
A type of machine that helps a lumberjack split wood.
What is a wedge? (an ax)
300
When students predicted how they thought the experiment would turn out they were formulating this.
What is an hypothesis?
400
A skateboard ready at the top of a skate ramp is an example of this.
What is potential energy
400
Newton's 3rd Law of Motion
What is for every action, there is an equal and opposite reaction?
400
Forces that are equal in size and opposite in direction.
What is balanced forces?
400
A type of simple machine used to help a person in a wheel chair get into a building that has steps.
What is an inclined plane? (a ramp!)
400
Something that provides proof in an experiment.
What is evidence?
500
A ball rolling down a hill is an example of this.
What is kinetic energy?
500
An in-line skater holding a basketball decides to throw the ball. The result is the basketball goes in one direction and the skater rolls backwards. This is an example of which Law of Motion?
What is Newton's 3d Law of Motion
500
one force thatis greater the other.
what is anUnbalanced force?
500
six types of simple machines.
What is a
pulley,
wedge,
inclined plane,
wheel and axel,
screw,
lever?
500
A scientific investigation in which one variable is changed and all the others are kept the same.
