Motion and Speed
A change in position over time
What is motion?
The rate at which velocity changes
What is acceleration?
A push or pull
What is force?
a force of attraction between objects due to their mass
What is gravity?
Any material that can flow and take shape of its container, and can flow because its particles easily move past each other
What is a fluid?
Describes the location of an object
What is position?
An increase in acceleration, from a small velocity to a large velocity
What is positive acceleration?
What is a net force?
Earth's gravity is one example of this type of force, which pulls, but does not push
What is an attractive force?
The measure of how much force is acting on a given area
What is pressure?
Change in y over change in x
What is the slope formula?
or
What is slope?
Always turning in a circular motion
What is centripetal acceleration?
The tendency of all objects to resist a change in motion
What is inertia?
What is a gravitational pull?
An upward force that fluids exert on all matter
What is a buoyant force?
A quantity that has both size and direction
What is a vector?
A decrease in acceleration, high velocity to low velocity
What is negative acceleration?
An object at rest, stays at rest, and an object in motion stays in motion at the same speed and direction, unless it experiences an unbalanced force
What is Newton's 1st law?
What is distance and mass?
equals mass divided by volume
What is density?
Speed in a certain direction
What is velocity?
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force
What is Newton's 3rd Law
The acceleration of an object depends on the mass of the object and the amount of force applied
What is Newton's 2nd law?
when gravity is pulling an object down and no other forces are acting on it.
What is free fall?
