Newton's Laws of Motion
"An object in motion will stay in motion" is part of this law of motion...
What is Newton's 1st Law of Motion?
The force that opposes an objects motion when it slides or rolls
friction
Objects moving in outer space will never slow down because this force is missing.
Air resistance
___________ are always involved in the starting of motion.
force
This is the energy an object has when it is in motion
Kinetic Energy
This law of motion states that all forces come in pairs...
What is Newton's 3rd Law of Motion?
Objects that are ___________ have less friction than objects that are sliding.
rolling
Why is there no sound in outerspace?
There is no air
__________ are always involved in the stopping of motion
forces
This is another name for stored energy
potential energy
This law of motion states that objects with less mass are easier to move...
What is Newton's 2nd Law of Motion?
You can reduce the maximum friction force by changing one of these things.
Currently, astronauts only travel to outerspace if they are going to the ___________________.
International Space Station
If the net force on an object is 0, then the object _______ change motion.
("will" or "will not")
Will not
The international space station draws its energy from this source
the sun/solar power
What is newton's first law of motion?
This surface is the smoothest surface on Earth and has almost 0 friction.
Ice
These are the only two reasons an object in outer space would stop moving or change its motion
it hits/collides with another object
it comes close enough to a large body (planet/moon) that it becomes affected by its gravity
_____________ forces will sometimes change an objects motion by making it speed up.
reinforcing
When a balloon is inflated, it has this type of stored energy
elastic potential energy
This law describes why it would require more force to push a boulder than to push a tennis ball.
What is newtons second law of motion?
This is when the maximum friction force is strongest
before an object starts moving
Outer space lacks these three forces that are commonly found on Earth and usually cause objects to stop moving.
gravity, air resistance, friction
_____________ forces will cause an object that is already moving to slow down or stop.
counteracting
_________ is the force that transforms potential energy into kinetic energy when an object falls from a high place.
Gravity
