KStirlingRiley's 5th Grade Motion & Design
Terms in this set (27)
the rate at which the velocity (speed & direction) of an object changes over time.
able to move through the air with as little air resistance as possible.
a force that air exerts on a moving object, a kind of friction that opposes (slows down) motion.
when all forces acting on an object are in balance; object does not move.
the ability to do work or to move something.
a push or pull that can make something move or change the way it moves.
a force that occurs when two objects rub together. It slows motion and converts energy of motion to heat.
a force of attraction between any two masses.
the tendency of an object to resist any change in motion.
energy of motion.
something that is lifted, carried, or supported.
simple machine; a bar that lifts or moves something at one end when the other end is pushed.
the amount of matter in an object.
the act of moving; to go from one place or position to another.
Newton's 1st law of motion
an object at rest remains at rest or an object in motion remains in motion until a force acts upon it (inertia).
Newton's second law of motion
when a force is exerted on an object, the force acts to increase the speed of that object, to change its direction, or to slow or stop its motion.
Newton's 3rd law of motion
for every action there is an opposite and equal reaction.
stored energy that can be released to become other forms of energy.
move something toward you.
a measure of how far an object moves in a certain amount of time. Speed = Distance / Time
Sir Isaac Newton
English mathematician and physicist, 1643 - 1727, who described gravity and the three laws of motion.
when opposite sides have unequal forces; the object moves.
the speed AND direction of an object's motion.
measurement of the force of gravity on an object.
the act of moving something.
a detailed drawing or blueprint.
the development and use of products or systems that solve problems and extend human abilities.
