Motion
True or false: Motion is the rate of change of velocity.
False: Motion is the action or process of moving or being moved.
what is the equation for force
force=mass X acceleration or f=ma
List the steps of the scientific method (in order)
observations, questions, research, form a hypothesis, test the hypothesis, draw a conclusion, record and organize your results
True or false: Theories are based on many pieces of evidence.
True or False- You have to wash your eyes out after every experiment.
False you only wash your eyes out if you get chemicals in your eyes.
What is speed?
Speed is the rate of change of position.
what is force?
a push or a pull
What is the initial explanation of a scientific question called?
True or false: A theory doesn't need to be well supported.
False. All theories should be supported
True or False- You're not to wear closed-toed shoes.
False- You are supposed to wear closed-toed shoes.
What is velocity?
Velocity is the speed at which an object changes position and direction.
if both forces are going in the same direction you blank the forces
add
What makes evidence that helps answer the important question or leads to a new question?
An investigation
What is the definition of a scientific theory?
A scientific theory is a broad explanation that is supported by evidence.
Do you have to wear goggles to protect your eyes?
Yes you need to protect your eyes at all times.
True or false: Acceleration is how fast an object or person speeds up.
True.
when force is applied to an object it can blank its blank
change and motion
What is the first thing a scientist should do after forming a hypothesis?
You should test the hypothesis by conducting an experiment.
What should you do when choosing between competing theories?
You should select the theory that makes the fewest assumptions.
What kind of clothes would you wear during the experiment outside?
No loose clothing, wear tight clothes.
What is motion?
blank forces do not change blank ,they have a net force of blank
balanced, motion, and 0
Which group of words is related to the steps of the scientific method? A. hypothesis, result, organization B. approach, research, conclusion C. Hypothesis, data, theory D. question, experiment, conclusion
D
Why do scientific theories need explanations?
Because they show connections and help connect the observations with phenomena in the natural world.
True or False- You have to do every experiment outside.
False- You can do some experiments inside.
