Potential vs. Kinetic
This is the "energy of motion." If it’s moving, it has this.
What is Kinetic Energy?
This is the unit used to measure Work.
What are Joules?
Power is defined as the ________ at which work is done.
What is Rate or Speed?
This machine is a flat, sloped surface, like a ramp.
What is an Inclined Plane?
This type of machine is made of two or more simple machines working together.
What is a Compound Machine?
This type of energy is stored based on an object's height above the ground.
What is Gravitational Potential Energy?
If you push a wall with 1,000 Newtons of force but the wall doesn't move, this is how much work you did.
What is Zero?
This is the unit of measurement for Power.
What are Watts?
This point is where a lever pivots or balances.
What is the Fulcrum?
Scissors are a compound machine made of a lever and this.
What is a Wedge?
When you stretch a rubber band on a catapult, you are storing this specific type of energy.
What is Elastic Potential Energy?
You push a cart with 10 N of force for 5 meters. This is the total work done.
What is 50 Joules?
Two students do the same work, but Student A finishes in half the time. Student A has more of this.
What is Power?
A flagpole uses this machine to change the direction of the force needed to lift the flag.
What is a Pulley?
This force is the main reason why machines are never 100% efficient.
What is Friction?
If you double the mass of a moving object, you also double this type of energy.
What is Kinetic Energy?
To calculate work, the force must be in the same ___________ as the motion.
What is Direction?
A motor does 100 J of work in 2 seconds. This is its power output.
What is 50 Watts?
This machine is essentially two inclined planes joined back-to-back, like an axe or a knife.
What is a Wedge?
When energy is "wasted" in a machine, it is usually transformed into this type of energy.
What is Thermal or Heat energy?
According to the Law of Conservation of Energy, energy cannot be created or this.
What is Destroyed?
You do 200 J of work to move a crate 10 meters. This is the amount of force you used.
What is 20 Newtons?
746 Watts is equal to one of these units, often used for car engines.
What is Horsepower?
Simple machines don't reduce the Work; they make it easier by trading Force for this.
What is Distance?
This is the term for the number of times a machine multiplies your input force.
What is Mechanical Advantage?
