Motion with non-uniform acceleration Flashcards
1
Q
Define uniform Gravitational field.
A
A region of space in which objects experience the same gravitational field strength.
2
Q
Define terminal velocity.
A
Maximum velocity a falling body can travel at because resistive forces equals the weight of the object.
3
Q
Define Viscosity.
A
A measure of a fluid’s resistance to flowing.
4
Q
Define Drag.
A
A frictional force opposing motion due to an object moving through a fluid; proportional to the square of the object’s speed; and proportional to the surface area of the object in the plane perpendicular to the direction of motion.
5
Q
Define a fluid.
A
A fluid is a substance that can flow, including liquids and gases.
