MCAT Test Physical Sciences (Physics) Here are some physics equations and relationships
that you should commit to memory before taking the physical sciences section of
the MCAT test. MCAT
Test Review Notes: Newton’s Laws of Motion
1st Law- (Law of Inertia) - A moving object will resist any change in velocity. A resting object with resist any change to begin moving. 2nd Law- (Force = Mass x Acceleration, F=ma) – The force of object in motion is equal to the mass of the object and the acceleration of the object. Force can be defined in terms of newtons (N). 3rd Law- Greater force must be applied to create
movement. A reaction force is
generated when another force is applied to an object.
The greater force will determine if movement is to occur. Velocity is the rate of change of position.
Acceleration is the rate of change of velocity. Waves Wavelength- the distance between the highest points of a
wave Amplitude- half of the height of a wave, from the top of a
crest to the bottom of a trough Momentum = Mass
x Velocity Acceleration = Change
in Velocity

Time Speed = Distance
Time Work=Force x Distance Power= F x D
T Power= Voltage x Current Watts=Voltage x Amperes Ohm’s law, V
= I*R I = current V = potential difference R = resistance
