Physics for Beginners: Equation Solver

IMPORTANT NOTE:
With the exception of the Converting Units section below, the data entered must be in S.I. units

Time should be in seconds. Distances should be in meters. Velocities should be in m/sec. Accelerations should be in (m/sec)/sec. Force should be in Newtons.

1. Converting Units
   • Length Conversions
     • feet to meters
     • meters to feet

   • Speed Conversions
     • miles per hour (mph) to meters per second
     • meters per second to miles per hour (mph)

   • Force Conversions
     • pounds to Newtons
     • Newtons to pounds

2. Kinematics: In one dimension and with a constant acceleration
   • Velocity Formula

     Solving for the velocity after the objects accelerates
     Solving for the time
     Solving for the acceleration
     Solving for the initial velocity

   • Distance Formula

     Solving for the distance the object travels after it accelerates
     Solving for the time the object accelerates. Note: There are two solutions: one corresponding to the (+) sign in the formula and one corresponding to the (-) sign in the formula. Refer to this section if you are unfamiliar with this formula.

3. Gravity
   • Weight: The force of gravity pulling an object downward at the surface of the earth

     Solving for the weight of an object

     W = mg

   • Gravity in Detail

     Solving for the gravitational attraction between two objects

4. Uniform Circular Motion
   • Force

     Solving for the force needed to make an object undergo uniform circular motion
