(Angled) Projectile Motion Hints & Formulas
I. Terminology applicable to ANGLED (not horizontal) LAUNCHES!
A. Initial velocity (V0) at launch angle => a vector describing the
characteristics of the velocity always break this into x (Vx) and y (Vy)

Chapter 4 Kinematics In Two Dimensions
4.1 The Kinematic Equations in Vector Form
In chapter 2 we discussed motion in one dimension only. And although the
displacement, velocity, and acceleration of a body are vector quantities, we did not
write them in t
1. Use equations below in order to do Linear Motion problems.
Equation 1: Speed, average speed, or velocity = d/t
Equation 2: Acceleration (a) = (V2 V1)/ (T2- T1)
Equation 3: At rest, V1= T1= 0: a = V/T - V = at
Equation 4: a = g (10 m/s2, starting at res

Momentum
Momentum is defined as: Momentum = Mass * Velocity
Velocity is a vector
Mass is a scalar
Momentum is a vector
When a scalar is multiplied times a vector the result is a vector
In order to change the momentum of

Property of moving things
Means inertia in motion
Review
Mass is a measure of the inertia an object has that is the resistance to changes in motion
Mass is a property
Newtons second law relates force mass and acceleration
