Water Bottle Rocket Vocabulary
Terms in this set (25)
a force that works against forward motion; friction between the air and the object in motion; air resistance
The force that two surfaces exert on each other when they rub against each other
a push or a pull exerted on an object
forces that are equal and working in opposite direction; these forces do not cause a change in an object's motion
forces that cause a change in an object's motion to change direction, speed up, slow down, or stop; the forces are not equal
The attractive force between objects
the property of matter that causes matter (objects) to resist any change in its motion in either direction or speed; laziness
a force that is used to push our rockets off the launcher; a pushing force
a force that acts on an object
a force that is equal and opposite of the action force
The state in which one object's distance from another object is changing.
any part of an experiment that can be changed; Examples: amount of water, number of fins, amount of mass in the nose cone
Newton's 1st law
(Law of Inertia) an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.
Newton's 2nd law
The acceleration of an object depends on the mass of the object and the amount of force applied
Newton's 3rd law
For every action there is an equal and opposite reaction
the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
The stabilizing and guiding unit of a model rocket.
What is the formula for speed?
calculated using the speed formula, but includes a reference direction
a change in motion; speeding up, slowing down, or changing direction.
Produces a change in motion; the net force is NOT zero
The product of an object's mass and velocity
A value that does not change
A measure of the gravitational force exerted on an object.
