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)
