What are some examples of MCAT physics equations?


Quick Answer

Some examples of MCAT physics equations include the equation for law of gravitation, which is F = Gm1m2/r^2; the equation for centripetal force, which is F=mv^2/r; and the equations for potential energy, such as PE = mgh, PE = 1/2kx^2 and PE = -GmM/r. Other equations include momentum = mv, impulse = Ft and KE = (1/2)mv^2.

The physics formulas used for the MCAT cover topics including translational motion, force, motion and gravitation, equilibrium, momentum, work, energy, waves, periodic motion, sound, fluids, solids, electrostatics, electromagnetism, electronic circuits, optics and atomic structure. Examples of formulas used in the electronic circuits section include I = ?Q/?t for current and C = Q/V for capacitance. Formulas covering topics in fluids and solids include ? = m/V for density, P = ?gh for pressure and depth, P + ½?v2 + ?gh = constant, which is Bernoulli's equation, and Av = constant for the continuity equation. Under the topics of work and energy, an example of an MCAT equation is F_weight(h) = mgh = ½mv^2, which is the formula for the work from gravity. Formulas for translational motion include those for average speed, average velocity and average acceleration. Other formulas may include those for static friction, kinetic friction, motion on an incline plane and movement of a pulley system.
