15 Questions
What is displacement?
Displacement is the change in position of an object.
What is distance traveled?
Distance traveled is the total length of the path traveled between two positions.
Is distance traveled always greater than or equal to displacement?
Yes, distance traveled is always greater than or equal to displacement.
What is a scalar quantity?
A scalar quantity is a quantity with magnitude or size, but no defined direction.
What is a vector quantity?
A vector quantity is a quantity having both magnitude and direction.
How can a vector be represented mathematically?
A vector can be represented mathematically as a set of components.
What is the method for determining resultants analytically?
When adding two vectors analytically, add the x-component of one vector to the x-component of the other vector. The result is the x-component of the resultant vector.
What is the formula for determining the magnitude of the displacement using the Pythagorean theorem?
$\sqrt{x^2 + y^2}$
What is a motion diagram?
A motion diagram shows an object’s position at several equally spaced moments in time.
What is a dot diagram?
A dot diagram is a motion diagram in which each position of the moving object of interest is represented as a single point.
What is uniform motion?
Straight-line motion in which the position changes the same amount in each time interval.
What is nonuniform motion?
Motion in which the position does not change the same amount in each time interval.
What is a position vs. time graph?
A graph of position as a function of time.
How can you represent a vector mathematically?
A vector can be represented mathematically using magnitude and direction.
What is the formula for determining the magnitude of a vector?
$|\mathbf{v}| = \sqrt{v_x^2 + v_y^2}$
