Newton’s first law of motion
An object at rest tends to stay at rest, and an object in motion tends to stay in motion at a constant speed in a straight line, unless acted upon by an unbalanced force.
Newton’s second law of motion
Acceleration = net force / mass
Law of universal gravitation
Fg = Gm1m2/r^2 G= 6.67x10^-11
Frequency
Rate of vibration, creates pitch, measured in hertz (Hz)
Doppler Effect
Source of sound, listener, or both are moving closer or farther apart
Electromagnetic spectrum
Lowest to highest: radio waves, microwaves, infrared waves, visible light, ultraviolet light, x-rays, gamma rays. In colors red has lowest frequency, violet the highest
Law of reflection
Angle of incidence is equal to the angle of reflection
Concave mirror
Or converging mirror, curve inward
Convex mirror
Diverges light away
Conduction
Heat transfer through contact
Convection
Heat transfer by moving heat particles
Radiation
Electromagnetic waves transmitting heat
