Science Newton Law Flashcards
How does gravity act on large and small objects? And how did Galileo Galilei change our thinking on this?
Gravity pulls everything together equally, objects fall at the same speed and rate if air resistance does not get in the way
Galileo Galilei proved the old thinking wrong by dropping two different sized objects off of the leaning tower of Pisa
Why do some objects fall faster or slower than others?
Some objects fall faster or slower because of the fact that air resistance can interfere with the objects. If they were more arrow dynamic they’d fall faster.
The lighter object will then fall slower, and the heavier faster.
Think back to the parachute with the peg.
The parachute would slow the peg by building air resistance.
What are Newton’s Laws? and relate them to actual occurrences.
The second of Newton’s Laws is Force = Mass x Acceleration
A real life situation would be pushing a table. The table is the mass and the force you are acting upon it with is the force. The object will accelerate with that force whereas if you apply the same force to an elephant the elephant will not move at all.
(When the mass accelerates it equals force, because the force is what makes the mass accelerate).
Go back on your notes of electromagnets
Using the electric currents of wire and a battery. The wire has electric currents flowing through its coils, which creates a magnetic field
Also, batteries have a positive and negative side in which the wire must access correctly.
How does gravity work with distance and density?
The more the object falls the faster it accelerates. If a ball falls for 2 seconds it will fall 4 centimeters.
Objects that are denser have a greater concentration of mass, thus creating a larger gravitational pull than a same-sized object with lower density.
