21
Q

Newton’s first law of motion

A

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.

22
Q

Newton’s second law of motion

A

Acceleration = net force / mass

23
Q

Law of universal gravitation

A 
Fg = Gm1m2/r^2
G= 6.67x10^-11
24
Q

Frequency

A

Rate of vibration, creates pitch, measured in hertz (Hz)

25
Q

Doppler Effect

A

Source of sound, listener, or both are moving closer or farther apart

26
Q

Electromagnetic spectrum

A

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

27
Q

Law of reflection

A

Angle of incidence is equal to the angle of reflection

28
Q

Concave mirror

A

Or converging mirror, curve inward

29
Q

Convex mirror

A

Diverges light away

30
Q

Conduction

A

Heat transfer through contact

31
Q
