Frefall Equations & 1D Motion

Frefall Equations & 1D Motion

1. Motion is defined as change in position of a body over time with respect to the surrounding. For the concept of motion in one direction, consider a motion of a body along a straight track.

4. Characteristics

   • A) Displacement B) Velocity C) Acceleration

5. An object in free fall experiences an acceleration of -9.8 m/s/.

   • If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.
     • If an object is projected upwards in a perfectly vertical direction, then it will slow down as it rises upward.
       • If an object is projected upwards in a perfectly vertical direction, then the velocity at which it is projected is equal in magnitude and opposite in sign to the velocity that it has when it returns to the same height.
