Five Essential Equations of Linear Motion

These 5 equations will help you solve Kinematics problems

 

ONE

equati5Finds the average velocity (or speed) when you are given an initial and a final velocity of a moving object.

noteIf the object starts from rest the value of v1 is zero

 

TWO

equati6 Finds the average velocity (or speed) of a moving object over a definitive distance and time period.

 


THREE


equati7Finds the final velocity of an object undergoing accelelration over a given period of time.

  noteIf the object starts from rest the value of v1 is zero 

 

FOUR

 

equati8

 

Finds the final velocity of an object given its acceleartion and displacement.

notedon't forget to take the square root to get to the answer for final velocity.

notethis equation can be rearranged to solve for the distance or dispalcement that an object travels given its velocities and acceleration.

noteIf the object starts from rest the value of v1 is zero

 

FIVE

equati9Finds the total distance traveled by an object over a period of time  if you are given its acceleration.  This is probably the most useful of the 5 equations.

 notememorize this equation!!!!

 

noteIf the object starts from rest the value of v1 is zero
