Matter & Measurement
What is the amount of matter in an object?
What is mass?
What force keeps us on the ground?
What is gravity?
What kind of energy is stored energy?
What is potential energy?
What is the first step in the scientific method?
What is asking a question?
What is the product of mass and velocity?
What is momentum?
Which tool would you use to find the mass of a rock?
What is a scale?
What is the tendency of an object to stay at rest or keep moving?
What is inertia?
What kind of energy is energy in motion?
What is kinetic energy?
What do you call a test you do to check a hypothesis?
What is an experiment?
How do you calculate momentum?
Mass × velocity.
What is the amount of space an object takes up?
What is volume?
What do you call the push or pull that opposes motion?
What is resistance (friction)?
Give an example of potential energy.
What is a cart at the top of a roller coaster?
What do you call the variable you change in an experiment?
What is the independent variable?
If two cars collide, what happens to their total momentum?
It is conserved.
If two objects are the same size but one has more mass, what can you say about the heavier one?
It is denser.
What is the force that keeps an object moving in a circle?
What is centripetal force?
What happens to potential energy when you lift an object higher?
It increases.
What do you call the variable you measure in an experiment?
What is the dependent variable?
What happens to momentum if speed increases?
It increases.
Why do scientists need standard units like grams and liters?
So measurements are clear and can be compared anywhere.
What law says, “For every action, there is an equal and opposite reaction”?
What is Newton’s Third Law?
How does mass affect kinetic energy?
More mass means more kinetic energy.
Why is it important to change only one independent variable at a time?
So you know what caused the result.
What does Newton’s First Law of Motion say about objects at rest?
They stay at rest unless acted on by a force.
