Physical parameter that shows a rate of change of velocity.
What is acceleration?
200
A force that always resists a relative motion of two objects
What is sliding friction?
200
A kind of energy that is carried by electromagnetic waves.
What is radiant energy?
200
The metric unit for measuring heat

300
A situation specifically set up to investigate something.
What is experiment?
300
A slope of coordinate vs. time graph
What is velocity?
300
When the net force is zero, objects keep moving with the same velocity.
What is the first law of motion?
300
A kind of energy due to object's position.
What is potential energy?
300
The amount of energy it takes to raise the temperature of one milliliter of water by one degree Celsius.
What is calorie?
400
The variable you keep the same during experiment
What is a control variable?
400
accelerating due to the gravity
What is a free fall
400
is directly proportional to the net force and inversely proportional to the object's mass.
What is acceleration?
400
A kind of energy that is associated with a moving object
What is kinetic energy?
400
A property of a substance that tells us how much heat is needed to raise the temperature of one kilogram of a material by one degree Celsius.
What is specific heat?
500
The way you actually do the experiment.
What is experimental technique?
500
An object moving in a curved path affected only by the gravity.
What is projectile?
500
is equal to the product of mass and velocity.
What is momentum?
500
This force does a work that is equal to mgh.
