Motion
A change in position over time.
What is motion?
A push or pull.
What is a force?
Force = mass x acceleration.
What is Newton's Second Law?
The rate at which velocity changes.
What is acceleration?
Any material that can flow and take the shape of its container.
What is a fluid?
How far something moves in a given amount of time.
What is speed?
The SI unit for force.
What is a Newton?
An object's tendency to resist change in motion.
What is inertia?
An increase in the velocity's speed.
What is positive acceleration?
The measure of how much force is acting on a given area.
What is pressure?
The SI unit of distance.
What is a meter?
An upward force that fluids exert on all matter.
What is buoyant force?
Force / mass.
What is acceleration?
A decrease in the velocity's speed.
What is negative acceleration?
The SI unit for pressure.
What is a Pascal?
Speed in a specific direction.
What is velocity?
A force of attraction between objects due to their masses.
What is gravity?
Things at rest stay in rest, things in motion stay in motion unless acted upon by an outside force.
What is Newton's First Law?
The SI unit for acceleration.
What is m/s2?
Two familiar fluids that exert pressure.
What are the atmosphere and water?
The length of a straight line between two positions.
What is displacement?
Forces that have a net force equal to 0N.
What are balanced forces?
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
What is Newton's Third Law?
A change in the velocity's direction.
What is centripetal acceleration?
The buoyant force on an object is equal to the weight of the displaced water.
What is Archimedes' Principle?
