a quantity that has magnitude only
a quantity that has BOTH magnitude and direction
The total length of a path an object travels. (how far you go)
The change in position of an object described by a vector that begins at the initial position and ends at its final position. (how far you go in a specific direction)
Particle Model of Motion
A simplified version of a motion diagram in which the object in motion is replaced by a single point.
the distance an object moves in a given time.
the displacement an object moves in a given period of time.
v-bar=average of v-final and v-initial
The rate at which velocity changes.
The ideal falling motion of an object in which the gravitational force is the only force acting on the object.
Acceleration due to gravity on Earth
The change in velocity in a given period of time as an object falls freely toward the earth.
g = 9.8 m/s2
d = vit + ½ at2
vf2 = vi2 + 2ad
