~velocity includes the speed and direction of an object 
~a change in velocity can either be a change in how fast something is moving or a change in direction it is moving 
~acceleration occurs when an object changes its speed
~acceleration also has direction just as velocity does 
~if acceleration is in the same direction as the velocity the speed increases and the acceleration is positive 
~if the speed decrease the acceleration is in the opposite direction from the velocity the acceleration is negative 
~a change in velocity can be either a change how fast something is moving or a change in the direction of movement 
~graphs of speed versus time can provide information about accelerated mot ]]> 2017-09-29 13:58:26 UTC https://padlet.com/vgrape/lpqi2jifkhc0/wish/192456635 vgrape https://padlet.com/vgrape/lpqi2jifkhc0/wish/192456904 ~acceleration is the rate of change  in velocity 
~to calculate the acceleration of an object he change in velocity is divided by the length of time interval over which the change occurred 
~to calculate the change in velocity subtract the initial velocity from the velocity at the end of the time interval 
~velocity includes both speed and direction 
~the unit for acceleration is a unit for velocity divided by a unit of time]]> 2017-09-29 13:58:57 UTC https://padlet.com/vgrape/lpqi2jifkhc0/wish/192456904 vgrape https://padlet.com/vgrape/lpqi2jifkhc0/wish/192457085 ~engineers use the laws of physics to design amusement park rides 
~the highest speeds and acceleration usually are produced on steel roller coasters ]]> 2017-09-29 13:59:20 UTC https://padlet.com/vgrape/lpqi2jifkhc0/wish/192457085
