Important Formulas to Memorize for the Test
Make sure to memorize the following key equations:
- Force (Newton’s Second Law): F = ma (Force = mass × acceleration)
- Gravitational Force: F = G(m1m2)/r² (Force between two masses)
- Work: W = Fd (Work = force × distance)
- Kinetic Energy: KE = ½mv² (Kinetic energy = ½ × mass × velocity squared)
- Potential Energy: PE = mgh (Potential energy = mass × gravitational acceleration × height)
- Momentum: p = mv (Momentum = mass × velocity)
- Ohm’s Law: V = IR (Voltage = current × resistance)
- Work-Energy Theorem: W = ΔKE (Work = change in kinetic energy)
- Ideal Gas Law: PV = nRT (Pressure × Volume = moles × gas constant × temperature)
