Motion and Speed
Description of the location of an object
What is position?
The rate at which velocity changes
What is acceleration?
Push or pull
What is a force?
A force of attraction between to objects due to their masses
What is gravity?
Any material that can flow and can take the shape of its container
What is a fluid?
Measurement of how far something moves in a given amount of time
What is speed?
Formula for acceleration
What is v2 - v1 over time?
Combination of all forces acting on an object
What is net force?
When gravity is pulling an object down and no other forces are acting on it
What is free fall?
The measure of how much force is acting on a given area
What is pressure?
Speed in a specific direction
What is velocity?
Increasing velocity
