Newtons Laws
State Newtons First Law
An object stays in motion or at rest until an outside force acts upon it
Is copper magnetic?
No
what is the formula for force?
F=MxA
What is a current?
Charged electrons moving through a conductor or space.
Is iron ferromagnetic?
Yes
State Newtons Third Law
For every action there is a equal or opposite reaction
Is aluminum foil magnetic?
No
What is the formula for speed?
S= d/t
What is the difference between a conductor and an insulator?
A conductor allows for electrons to flow freely, whereas, insulators do NOT allow for electrons to flow freely.
Is copper a metal? If yes then if it magnetic? If no then why not?
Yes, no, does not have electrical properties to make it magnetic
Force= MXA is which of Newtons Laws
Newtons Second Law
What makes an object magnetic
The properties in the object have a magnetic force that pulls it toward the magnet
Calculate force a man hits a baseball with a mass of .14 kg which accelerates at a rate of 50 meters per second. What is the force that as acted on the ball?
.14 kg x 50 m/s
A battery transfers its energy to an object by?
Allowing the electrons to flow to the positive side to turn on the object
If a rock weighs 100 Newtons on Earth what would it weigh on Mercury and Jupiter?
Less on mercury & more on jupiter
Your car is traveling at 50 mph and the car continues to travel at this speed, why?
Newtons 1st Law
List five objects in your daily life that you use which are magnetic
fridge, stove, computer, car, microwave, fish tanks
Mike jogs 30.5 km in 6 hours find his speed, how did you do it?
30.5 divided by 6
Is turning on the lights an open or closed circuit? Why?
Closed
Force that are not equal are what?
Forces that are equal are what?
What is friction?
What is the relationship between mass and inertia?
unbalanced, balanced, a resistance of objects, the more mass an object has the more inertia it has.
1- An object in motion stays in motion until acted on by an unbalanced force
2- F=MXA
3- For every action there is an equal or opposite reaction
What is ferromagnetism, give me 2 examples
Makes natural objects magnetic
-Iron, Colbalt, Body Glitter
What is the formula for acceleration, speed, and force? Provide an example of one.
Acceleration velocity 2 - velocity 1 divided by time 2 and time 1, speed equals distance divided by time, and force equals mass x acceleration
Is turning off the lights an open or closed circuit? Why?
Open
What is the formula for speed and force?
What is seen in the middle of March and April but can not be seen at the beginning or end?
What is something that goes up but never comes down
Knights run to attack but never return to save the king?
S=d/t and F=mxa
the letter R
age
