The mechanical advantage of a pulley system with 6 points of contact
What is 6?
100
Work output / work input
What is efficiency?
100
This property is mass per volume. Floating objects must have less of it than the liquid in which they are floating.
What is density?
100
A balloon is propelled forward with a force equal to the force of the air leaving out the hole, thanks to this law.
What is what is Newton's third law, or for every action there is an equal and opposite reaction?
200
This term is not a force.
What is centrifugal?
200
The volume in mL that a submerged 275 cm^3 potato displaces
What is 275 mL ?
200
For a ramp, input distance / output distance or length / height
What is mechanical advantage?
200
This object survived a great fall if its toothpick contraption broke or collapse on impact with the ground
What is an egg?
200
Contrary to intuition, as you add strings to your pulley this property actually goes down. Curse, you friction!
What is efficiency?
300
This quantity is the product of rotational inertia and rotational speed
What is rotational momentum?
300
The buoyant force of a object that has a weight of 2N but and apparent weight of 1.5 N when submerged in water.
What is .5 N?
300
These multiple or change the direction of a force
What is a simple machine?
300
A trebuchet that uses a sling has less of this property than a traditional catapult.
What is rotational inertia?
300
This type of friction will always be greater than kinetic friction.
What is static friction?
400
This term describes the number of rotations per amount of time.
What is rotational speed or velocity?
400
The momentum of a 5kg marmot travelling 10 m/s
What is 50 kg m/ s ?
400
This quantity is the amount of force exerted on a certain amount of area
What is pressure?
400
In simple machines lab, we concluded that the most efficient way to raise an object's potential energy was to do this.
What is to lift an object without using a simple machine or to lift it yourself?
400
In the hole-in-one egg ramp lab, this quantity of the metal marble remained constant regardless of the height of the ramp. Good thing because gravity does not affect it.
What is initial velocity in the x- or horizontal direction?
500
This term describes the number of times any event occurs per second.
What is frequency?
500
A ninja throws a shrunken head straight up in the air at 50 m/s. This is the time it takes for it to come to its highest point.
What is 5 seconds?
500
This quantity is calculated by multiplying an object's mass by acceleration due to gravity and its height in meters from a chosen reference frame (usually the ground).
What is Potential energy or gravitational potential energy?
500
This caused the dots on the spark tape to increase in distance as the weight fell
What is acceleration or acceleration due to gravity?
500
The difference of the experimental value and the actual
value, divided by the actual value, multiplied by 100
