Unit 1 - Kinematics

Vector vs Scalar

Vectors have magnitude and direction

Scalars solely have magnitude

Displacement Formula

final position - initial position

Slope of Displacement

velocity

Slope of Velocity

acceleration

Average Velocity Formula

displacement/time

Instantaneous Velocity

the speed and direction of an object at a particular instant

Acceleration

The rate at which velocity changes

Velocity

Speed in a given direction

Area under velocity vs time graph

displacement

Area under acceleration vs time graph

change in velocity

Kinematic Equations

V = Vo + at

ΔX = Vot + 1/2at^2

V^2 = Vo^2 + 2aΔx

Δx = 1/2(Vo+V)t

Free Fall

the motion of a falling object when the only force acting on it is gravity

Gravity Acceleration

9.8 m/s^2

Projectile On an Angle Formula X

Vocos(theta)

Projectile On an Angle Formula Y

Vosin(theta)

What shape is trajectory?

parabolic

Level Range Equation

Δx = (2Vo^2sin(2theta))/g

or

Δx = (2Vo^2cos(theta)sin(theta))/g
