Kinematics in Two or Three Dimensions; Vectors
Vectors and Scalars
Vector
Magnitude and Direction
Displacement, velocity, force, momentum
Scalar
Magnitude
Mass, time, temperature
Addition of Vectors
One dimension
Add/Subtract with signs concerned
Two dimensions
Right angles to one another
Pythagorean Theorem
Not right angles
Tail-to-tip method
Parallelogram method
Subtraction of Vectors
Negative of a vector
Same magnitude, opposite direction
Multiplication of Vector by Scalar
Scalar is positive
Same direction with magnitude multiplied
Scalar is negative
Opposite direction with magnitude multiplied
Adding Vectors by Components
Components are perpendicular
Angle => Trigonometric functions
Magnotude => Pythagorean method
Unit vectors
Vector Kinematics
Two/Three Dimensions
Displacement = vector
Change of time and change of displacement is small
Instantaneous velocity
Instantaneous Acceleration
Projectile Motion
Two dimensions
Parabolic path
Vertical component
a = constant
Use kinematic equations
Horizontal component
a = 0
Use v=s/t
Motion of object near Earth's surface under influence of gravity
Relative velocity
Add/Subtract vectors
Each velocity labeled with object followed by reference frame
