Simple Machines
Set of toothed wheels that fit together; when turned, they allow a conversion between speed and force.
What are gears?
The measurement of the change in an object's velocity (direction and or speed).
What is acceleration?
The force of attraction that exists between any two objects with mass.
What is gravity?
The standard unit of measure for power.
What is watt?
Anything that as mass.
What is matter?
A surface that is tilted at an angle in order to help move heavy objects.
What is an inclined plane?
The measurement of how fast an object moves.
What is speed?
Any object in motion will continue to move in the same direction and speed unless external forces act on it.
What is the First Law of Motion?
The energy stored by an object.
What is potential energy?
Standard unit of measure for energy.
What is a joule?
A bar or board that rest on a support called a fulcrum.
What is a lever?
A measurement of mass in motion.
What is momentum?
The specific force that causes the attraction described by gravity.
What is gravitational force?
The ability to do work.
What is energy?
A measurement of how much matter is in an object.
What is mass?
A wheel with grooved rim for rope that causes a change in direction of force applied to the rope.
What is a pulley?
An object's overall change in position.
What is dispacement?
The greater the mass of an object, the more force it will take to accelerate the object.
What is the Second Law of Motion?
The energy an objection has due to its motion.
What is kinetic energy?
The force of gravity on an object.
What is weight?
A round device with a rod inserted at the center used to help move objects and remain stable.
What is a wheel & axle?
The rate of change in an object's speed or direction.
What is velocity?
For every action there is an equal and opposite reaction.
What is the Third Law of Motion?
A measurement of the rate at which energy is used.
What is power?
A quantity that has both a magnitude (size) and a direction.
What is a vector?
