6. Motion V=d/t Kinematics- the study of motion of an object
Motion involves:
Displacement (d)- measure of change of position
Time (t)- time it takes to change position
Velocity (v)- change in position per interval of time
V=d/t

7. Force A force is a push or pull on an object
Force is measured in Newtons which is a
kilogram times a meter per second
squared.
Force = mass x acceleration
Force of gravity keeping the riders in their seats.

8. Uniform Acceleration & Kinematic Equations
Uniform Acceleration occurs when the speed of an object changes at a constant rate.
Formulas:
d=1/2t(Vf+Vi)
Vf=Vi+at
d=Vi(t)+a(t)^2
Vf^2=Vi^2+2a(d)
Uniform acceleration is measured in meters per second squared.
d= displacement
a= acceleration
t= time
Vi= initial velocity
Vf= final velocity

9. Vector Vector- anything that has magnitude and direction
Vector Resolution- the process for determining the magnitudes of components of a vector in 2 dimensions
Formulas:
V x-axis= vector x (cosine of the angle)
V y-axis= vector x (sine of the angle)
Resultant= (R x^2 + R y^2)^1/2
V= vector
Rx= resultant of
x-axis
Ry= resultant of
y-axis

10. Work and Energy Potential Energy- energy of position or configuration
Conservation of Energy- energy cannot be created or destroyed
U= m(g)(h)
u- potential energy
m- mass
g- acceleration due to gravity
h- height above zero point
Ki- intial kinetic energy
Ui- intial potential energy
Kf-final kinetic energy
Uf-final potential energy
Ki + Ui = Kf + Uf

11. Momentum
Momentum is the measure of how hard it is to stop an object, which deals with Newton’s 2nd Law.
Formula:
P= m(v)
The unit for momentum is a kilogram times a meter per second.
P- momentum
m- mass
v- velocity

12. Thermodynamics
Thermodynamics is the study of heat, thermal energy, and
involves:
States of matter
Temperature
Heat
Thermal equilibrium
Change of state
Thermal energy transfer
Laws of Thermodynamics
Thermal energy- the internal motion of the molecules that make up an object

13. Waves and Energy Transfer
Wave motion transports energy from one point to another.
Wave pulse:
Traveling wave:
3 Types of Waves:
Mechanical
Electromagnetic
Matter

14. Waves
Reflection of waves:
Refraction of waves:
Diffraction of waves:

15. Sound Waves Sound waves are the compression of waves.
The frequencies of a sound wave is the number of oscillations per second.
Amplitude is the loudness of the sound.
The speed of sound in air formula:
(T)
T- temperature

17. Light Waves The study of light is called ray optics.
Colors of the Spectrum
The study of light is called ray optics.
Light waves travel in a straight line path, therefore represented by a ray.
The speed of light waves in a vacuum (c) is constant.
c= 3 x 10^8 meters/per second R E D O A N G Y L W B U I V T
