Scientific Process
What is the main purpose of a hypothesis in an experiment?
To make a testable prediction.
What is kinetic energy?
What is the energy of movement?
How does mass affect acceleration when a constant force is applied?
More mass means lesser acceleration.
What is a polymer?
a. A type of metal
b. A large molecule made up of repeating units
c. A single atom

Which of the following is an example of a constant variable in an experiment?
a. The temperature at which a plant grows
b. The amount of sunlight the plant receives
c. The type of soil used for all plants
d. The height of each plant
What is C?
What is potential energy?
The stored energy in an object.
What does Newton's First Law of Motion state?
An object at rest stays at rest, an object in motion stays in motion unless acted on by an unbalanced force.

What is a monomer?
The smallest unit of an element is known as:
What is an atom?
What is an independent variable?
What is a variable that changes?
Which type of energy is associated with objects that can fall due to gravity?
What is gravitational potential energy?
What cause a ball to fall back to the ground?
What is gravity?
How do polymers affect everyday life?
a. They are only used in laboratories
b. They have no significant impact
c. They are used in products like clothing and bottles
d. They are harmful and not used
What is C?
Thermal energy is related to the movement of what in an object?
The movement of molecules?
What is the role of the dependent variable in an experiment?
The variable that is measured or observed.

What is C?
Which type of energy is stored within chemical bonds?
The law of conservation of mass states that?
Mass is the same before and after a reaction?
What does the term 'system' refer to in a scientific experiment?
What is a group if interacting parts?
What does the law of conservation of energy state?
Energy can't be created or destroyed.
What is the relationship between force and acceleration according to Newton's Second Law?
a. Force is inversely proportional to acceleration.
b. Force is directly proportional to acceleration.
c. Force is independent of acceleration.
d. Force is equal to energy.
What is B?
What type of energy does every chemical reaction need?
What is activation energy?
In an endothermic reaction, energy is:
Energy is absorbed from the surroundings.
