F
A chemical reaction in which a substance reacts rapidly with oxygen, often producing heat and light
What is a Combustion Reaction?
the distance an object travels plus the direction from the starting point
What is Displacement?
A covalently bonded group of atoms that has a positive or negative charge and acts as a unit.
What are Polyatomic ions?
A chemical reaction that absorbs energy from its surroundings?
What is an Endothermic Reaction?
The time rate of change of an object's velocity
What is Acceleration?
This occurs when you push something to get it started.
What is sliding friction?
Fluid friction also acts on objects moving through air.
What is air resistance?
Friction that opposes the initiation of motion
A physical measurement that contains both magnitude (number) and directional information
What is Vector Quantity?
A frictional force that acts on rolling objects
What is rolling friction?
A force that results when surfaces of objects rub against each other and oppose motion
What is friction?
The motion of an object when it is falling solely under the influence of gravity
What is free fall?
For every action, there is an equal and opposite reaction
What is Newton's 3rd Law of Motion?
The SI unit for force, abbreviated as N. One _______ is the force required to make an object with the mass of 1 kilogram accelerate at 1 meter per second squared
What is Newton?
An object in motion (or at rest) will stay in motion (or at rest) until it is acted upon by an outside force; also referred to as the law of inertia
What is Newton's 1st Law of Motion?
Friction that opposes motion once the motion has already started.
What is Kinetic friction?
Force-carrying particles that hold quarks together.
The tendency of an object to resist changes in its velocity
What is inertia?
A subatomic particle scientists theorize to be among the basic units of matter- one that cannot be split into smaller parts- but of course they're still looking for smaller ones.
What are quarks?
A push or pull that acts on an object?
What is force?
A small force-carrying particle that is responsible for the force of gravity
What is a Graviton?
States that every object in the universe attracts every other object.
What is Newton's Law of Universal Gravitation?
What are the 4 different kinds of forces that physicists think exist in creation?
What is Strong Nuclear Force, Weak Nuclear Force, Electromagnetic Force, and Gravitational Force?
What is the General Theory of Relativity?
When an object is acted on by one or more unbalanced forces, the net force is equal to the mass of an object times the resulting acceleration
What is Newton's 2nd Law of Motion?
