is the friction between an object and particles in the air.
is determined by dividing the trip distance by the total time of the trip.
exist when all the forces acting on an object result in the object staying at rest or moving at a constant speed in the same direction.
is a push or a pull that touches or comes in contact with an object to change motion.
is the path along which something moves, lies, or points. Some direction terms are: right, left, north, south, up, down, etc.
is a measurement of how far from each other two points or places are.
is the force exerted by the user on the simple machine.
is produced when electricity flows through a wire. Coiling a wire around an iron bar increases the strength of the magnetic field.
is a push or a pull on something.
force on a load
is the force exerted by the simple machine on the load. All simple machines involve a force on the load and an effort force.
is a force that acts on an object when it rubs against another object or material.
is the fixed point on which the lever moves.
is a representation of data plotted on an x-axis and y-axis.
is a force where one object pulls on another object.
is a simple machine made with a flat slanted surface.
is how fast an object moves at a certain point in time.
is a bar that tilts around a fixed point to produce a useful motion.
is the object to be moved by the simple machine.
is the measure of the amount of matter in an object.
is the changing of position of an object.
is a metric unit used to measure the force applied to objects.
is a push or a pull that does not touch an object to change motion.
point of reference
is a background or non-moving object in the background used in describing the motion of another object.
is a simple machine that is made up of a wheel with a groove in it.
is a simple machine that is an inclined plane wrapper around a rod or core.
is a device that makes a job easier to do by changing the amount of force, the direction of a force, or the distance through which a force moves.
is the measurement of how fast an object travels from one point to another.
is used to measure the approximate weight, or the pull of gravity, on an object.
is the measurement of the period between events or how long it takes an object to move from one place to another.
exist when all the forces acting on an object result in a change of motion of the object. If it was at rest, it begins to move. If it is moving, it changes speed or changes direction.
are the properties of things that can change, be changed, or vary in an investigation. Some examples are time, distance, and temperature.
is a simple machine that helps cut or split objects.
is the measure of the amount of gravity pulling on an object.
wheel and axle
is a simple machine that has a center rod that is attached to a wheel.
