GRAVITY HOLDS ME DOWN
BAD BAD FOSSIL FUELS
ISAAC "FIG" NEWTON
WORK WORK WORK
MAY THE FORCE BE WITH YOU
100
though there is gravity, this keeps a parachute in the air longer
What is air resistance?
100
getting power from organic material (plants/animal waste)
What is biomass?
100
this can stop a desk from sliding across the floor
What is friction?
100
the unit for work
What is a joule?
100
all objects tend to resist any change in motion
What is inertia?
200
this is a measure of the amount of matter an object has
What is mass?
200
this type of alternative energy can produce radioactive waste
What is nuclear energy?
200
This law is demonstrated when a car suddenly stops and you keep moving forward until your seatbelt stops you
What is the 1st law?
200
the unit for power
What is a watt?
200
the planets do this around the sun
What is orbit?
300
this can change, but mass can not
What is weight?
300
this is one con that all alternative energy sources have in common
What is they are expensive to start?
300
This is demonstrated when a rabbit kicks off the ground and jumps up
What is the 3rd law?
300
work divided by the time it takes to do it is this
What is power?
300
you must do this to find net force on an object if the forces are in opposite directions
What is subtract?
400
this is the path that a thrown object follows
What is projectile motion?
400
this alternative energy source can harm wildlife, especially aquatic ecosystems, when built
What is hydroelectric energy?
400
This law is demonstrated when you have to use mroe force to push a heavy shopping cart, and less force to push an empty one
What is the 2nd law?
400
W= F x d If a 10 N object is moved 4 meters, how much work is done?
What is 40 Joules?
400
if 2 objects move closer together, their gravitational force does this
What is increase?
500
this is why you feel Earth's gravitational pull more, even though the sun has more mass
What is because you are closer to Earth?
500
this fossil fuel was once the major source of energy in the US, and causes a huge amount of environmental damage
What is coal?
500
this states that all objects attract each other through force, and this force is affected by mass and distance
What is Newton's law of universal gravitation?
500
if force or distance are increased, what happens to the amount of work done?
What is increases?
500
A more massive object is ___ to accelerate.
What is harder?
