SPhysical Science Review Part 1

What is a possible answer or explanation to a question based on knowledge, observations, and research?

HINT: It is often written in "if...then" format.

• Observation

• Hypothesis

• Experiment

• Conclusion

Answer explanation

A hypothesis should by a clear and simple statement that can be tested.

Will our results always support our hypothesis?

Why is it important to write down your procedure?

• So that I can photocopy it for my friends.

• To take up more class time.

• So that other scientists can repeat it.

• So that I don't have to do it later.

Answer explanation

A procedure should be written clear enough so that other scientists can duplicate the experiment exactly.

What do we do if a part of the procedure isn't working?

The information gathered from making observations is called ____.

• data
• experiment

• graph

• procedure

• 270.6 km/hr

• 270.6 mph

• .0039 km/hr

• 2403 mph

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law

• Newton's second law

• Newton's third law, the law

• The law of universal gravitation

Newtons 3rd Law of Motion states:

• An object at rest will remain at rest unless acted upon by an outside force.

• For every action, there is an equal and opposite reaction

• The greater the mass of an object, the more force it will take to accelerate the object

An object and rest will stay at rest and an object in motion will stay in straight line motion unless acted on by a force, is which one of Newton's Laws of Motion?

• 4th Law of Motion
• 1st Law of Motion
• 3rd Law of Motion
• 2nd Law of Motion

Newtons 2nd Law of Motion states:

• An object at rest will remain at rest unless acted upon by an outside force.

• For every action, there is an equal and opposite reaction

• The greater the mass of an object, the more force it will take to accelerate the object
