Unit of Inquiry Flashcards
What is Newton’s first law of motion?
The first law says that any object in motion will continue to move the same direction and speed unless forces act on it.
What is Newton’s second law of motion?
The further you want something to go, the harder you must push/kick/throw it. The heavier something is, the harder it is to move. 
What is Newton’s third law of motion?
For every action there is a equal and opposite reaction. For Example: when you press your pedals on your bike (action) then the bike moves forward (reaction).
What’s something you do every day the goes with the first law of motion?
•What mom/dad hits the breaks on the car fast
When mom/dad hit the breaks my seat belt stops and I keep moving forward.
What’s something you do every day that goes with the second law of motion?
•Kicking a football into the goal
I kick the ball as hard or as soft as I want depending on wear and how far I want it to go. Then when it hits the net the force of the net hitting the ball makes the ball stop moving.
What is something that you do every day that goes with the third law of motion?
•Scootering to school
You push back with your foot (action) then you moved forward (reaction)
What’s the difference between contact and non-contact forces?
Contact: when you’re actively doing something like cracking a nut. You must apply force to the cracker in order for the nut to crack open.
Non-contact: when you don’t have to actively do something. Magnets sticking together; it doesn’t need you to apply any forces to anything to them stick together. 
What is acceleration?
Acceleration: when a car starts moving faster and faster by the second.
What is deceleration?
Deceleration: when a car starts getting slower and slower by the second.
What is constant speed?
Constant speed: when your car keeps moving at the same speed for a certain period of time.
What is the difference between weight and mass?
Weight: is a force. It is the forces of gravity pulling on a object.
Mass: the real weight without gravity pulling down on a object
What is air pressure?
Air pressure is the weight of molecules pressing down on the earth.
How does air pressure affect us?
The higher you go the air pressure gets less dense. When we go on a airplane ride and our ears pop then it means that the air pressure is changing.
How does high and low pressure affect the wether?
If air pressure is low then it means there’s a storm on the way.
When the air pressure rises then fair wether is coming.
If the air pressure you have remains steady then the wether you have now will remain the same.
How can the differences in air pressure creat wind?
When high air pressure goes into areas of low pressure then wind starts blowing. The greater the difference in pressure the faster the wind will blow.
