What type of energy means energy through movement?
What is "kinetic energy"
100
What is the definition of a lever?
What is " a relatively stiff object"
100
What is the definition of a Pulley?
What is " a wheel with a groove that uses a string to lift heavy objects"
100
What is the definition of an inclined plane?
What is "a sloping object that connects a high point with a low point"
100
What is the definition of a wheel and axle?
What is " a lever that rotates in a circular direction around a fulcrum"
200
What type of energy means that "stored Energy"?
What is "Potential Energy".
200
What are the 4 components of a lever?
What is the "Fulcrum, Effort, Load, Lever"
200
Which type of pulley requires less effort to lift a load?
What is "A free pulley."
200
What are 2 other types of simple machines that are considered to be inclined planes?
What is "a screw" What is "a wedge"
200
A wheel an axle magnifies the effort of a small force and turns it into a big force. How does this relate to a steering wheel in a car?
What is " it takes a small force to turn the steering wheel, but that magnifies/makes the force bigger so that you can move a 4000 pound car."

1.If you drop a ball, what type of energy is being displayed? 2Where would the ball have the most of this type of energy? - before being dropped - in the middle - right before it hits the floor
What is "Kinetic energy" what is "before it hits the floor"
300
What happens as the fulcrum is begins to be placed closer to the load? What is the trade-off taking place?
What is " The closer the fulcrum is to the load the easier it is to lift the load/ the less force is needed? What is "the trade-off taking place is force DECREASES while distance INCREASES"
300
A _______________ _____________________ is a when free pulley is combined with a fixed pulley.
What is "A pulley system"
300
What is the definition of a screw?
What is "a cylinder with an inclined plane wrapped around it"
300
What is the definition of a wedge?
What is " a simple machine that chops/cuts things into pieces"
400
What is the difference between mass and weight?
What is "Mass is the amount of space an object takes up, it is constant regardless of location, and it is measured in grams." What is "Weight is based on the pull of gravity on an object, it changes based on location, and it is measured in Newtons.
400
Draw a label a picture of a second class lever. Make sure to label all 4 components.
What is "view scholar illustrations"
400
What is the difference between a fixed pulley and a free pulley?
What is "A free pulley is located at the bottom, is able to move, and requires less for to lift an object. What is "A fixed pulley is located at the Top, doesn't move, and doesn't change the amount of force necessary to lift an object."
400
Person 1: has a screw with 3 threads Person 2: Has a screw with 17 threads. Each person needs to force the screw into the doorknob. Which person does more work? Explain.
What is "both do the same amount of work" because person 1 uses a lot of force but only turns it a few times WHILE person 2 has to use a small amount of force but has to turn it many times.
400
Ms. Collins has a sharp butter knife. Mr. Dimatteo has a dull butter knife? Who will be able to do more work easily and why? What type of simple machine are Ms. Collins and Mr. Dimatteo using?
Who is "Ms. Collins because it makes a sharper edge makes it easier to chop/cut things into pieces. What is "a wedge"
500
If you have a box with 3 Newtons pushing down from the top, 3 Newtons pushing up from the bottom, 7 Newtons pushing on the right side and 5 Newtons pushing on the left side, Which way will the box move? What is it's net force?
What is "move to the right" What is "net force of 2 Newtons"
500
_____ class of levers are similar to these ______ types of pulleys. How are they similar? Hint: Think about the direction of the force and the effort in both.
What is " A class 1 lever is similar to a fixed pulley because in both the effort is being pushed down and the load goes up. What is "A class 2 lever and a FREE pulley because in both the effort and load move up in the same direction.
500
Newton's first law of motion states what?
What is " An object in motion will stay in motion unless an opposing force of equal or greater force is pushing against it" Known as being in a state "inertia"
500
Lebron shoots a 3 pointer and the ball goes in the hoop. This is an example of which of Newton's laws? Explain?
What is "Newton's 3rd law of motion"
500
"Double Jeopardy" What is the difference between a controlled and manipulated variable? Give an example
What is " A manipulated variable is something that is changed on purpose in an experiment" What is "A controlled variable is something that is held constant in an experiment and can be regulated/controlled."
