kinematics
describing motion through properties such as position, time, velocity, and acceleration
Dynamics
concerned with the causes of motion which involves force
scalar
quantity that is fully described by magnitude only (speed, distance, time)
Vector
quantity that has both magnitude and direction (displacement, velocity, acceleration, force and momentum)
displacement
objects overall change in position
has both magnitude and direction
displacement formula
∆𝑥 = 𝑥𝑓 − 𝑥i
resultant displacement (total)
the result of adding 2 or more vectors
average velocity
the rate at which position changes at a given time
average velocity formula
𝑣 = ∆𝑥 ∆t
average acceleration
the rate at which velocity changes
average acceleration formula
𝑎 = ∆𝑣 /∆𝑡 = 𝑣𝑓−𝑣i / 𝑡𝑓−𝑡i
instantaneous velocity
how fast an object was moving along its path
derivatives
instantaneous rate of change of a function with respect to one of its variables
