Motion and Speed
The location of an object
What is Position?
The rate at which velocity changes.
What is acceleration?
Simply a push or pull.
What is a force?
A force of attraction between objects due to their masses.
What is gravity?
Any material that can flow freely and takes the shape of its container.
What is a fluid?
A location to which you compare other locations.
What is a reference point?
A = (V2 - V1)/ T
What is the formula for acceleration?
Newton (N)
What is the unit used to express force?
Earth's gravity
What is a attractive force?
The measure of how much force is acting on a given area.
What is pressure?
A change in position over time.
What is motion?
A decrease in the magnitude of velocity.
What is negative acceleration?
A combination of all the forces acting on an object.
What is a net force?
F = mass x acceleration
What is the formula for force?
P = Force/Area
What is the formula for pressure?
A quantity that has both size and direction.
What is a vector?
A increase in the magnitude of velocity.
What is positive acceleration?
Balanced forces have a net force of
What is 0N?
9.8 m/s/s
What is the acceleration you multiply by to find gravity?
The pressure caused by the weight of the atmosphere.
What is atmospheric pressure?
Speed in a specific direction.
What is velocity?
(m/s) or (m/s2) or (m/s/s)
What are the units for acceleration?
The tendency of all objects to resist a change in motion.
What is Inertia?
When gravity is pulling it down and no other forces are acting on it.
What is free fall?
A upward force that fluids exert on all matter.
What is a buoyant force?
