When you drop a marble, what does gravity cause it to do?
Stop
Move at a constant velocity
Accelerate
If something isn't moving at all, what is its velocity?
positive
negative
zero
If a marble rolls at a constant velocity on a completely flat surface, what is it doing?
Moving a certain distance every second in the same direction
Increasing its speed by a certain amount every second
Remaining in the same position for a certain amount of time
If a marble is accelerating, it is
moving fast
changing it's speed or direction
not moving at all
A force is defined as
a push or pull
something Yoda uses in Star Wars
some other third thing
Newton's First Law states:
An object in motion or at rest will remain that way unless an unbalanced force acts on it.
An object in motion or at rest will eventually come to a state of rest.
An object in motion or at rest will eventually begin to move.
Unless somebody knocks your Rube Goldberg machine over, it will
remain where it is.
start to mysteriously move across the room on it's own.
spontaneously combust.
What did you learn from Newton's Laws from the Rube Goldberg Machine?
The heavier the object that falls, the more force it will produce.
The heavier the object that falls, the less force it will produce.
All objects that fall produce the same amount of force.
What did you learn about Newton's 2nd Law from the Rube Goldberg Machine?
The harder you push on something, the less it will speed up.
The harder you push on something, the more it will speed up.
The harder you push on something, it won't change its speed
Newton's 3rd Law states that if you push an object like a wall,
there is no force because the wall doesn't seem to move.
the wall will move just as much as you do.
the wall will push back with equal force in the opposite direction.
A system possesses energy if it has the ability to do work. To do work is to apply a certain amount of force for a certain amount of distance.
True
False
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
True
False
The higher up you hold a marble, the more energy is stored (potential energy). This energy can be converted into more speed (kinetic energy).
True
False
As a marble falls farther and farther, it will have
more kinetic energy, and less potential energy
more potential energy, and less kinetic energy
