Definitions
The rate at which velocity is changing. The change may be in magnitude, direction, or both.
What is Acceleration?
This is your walking speed when you walk 30 m in 6.0 seconds.
What is 5 m/s?
Acceleration due to gravity is ALWAYS this on Earth.
What is 9.8 m/sec2?
What is the speed of an apple thrown straight up into the air when it reaches its highest point?
zero
At what Atlanta college or university did Coach Owen, the most amazing teacher of all time, get his Bachelor of Science Degree in Management?
What is the Georgia Institute of Technology?
The rate at which an objects distance changes.
What is speed (or velocity)?
A car at rest accelerates to a speed of 28 m/sec in 7 seconds. It has this for acceleration.
What is 4 m/sec2?
A bullet shot from a gun and an object dropped from the same height will do this (assuming no air resistance)
What is hit the ground at the same time?
In a vacuum a feather and a bowling ball will hit the ground at this time.
What is the same time?
Gravity is constant. This also is constant and unchanging.
What is God's love for his people?
Motion under the influence of the gravitational force only.
What is Freefall motion?
Sara kicks a soccer ball with a velocity of 5 m/sec, and it took 2 sec for the ball to get into the net. Therefore she was this many meters from the goal.
What is 10 m/s?
An object launched straight vertically in the air has this velocity at its maximum height.
What is zero (0 m/sec)?
Since a ball is thrown straight up into the air is slowing down, then it has this
What is negative acceleration due to gravity-9.8m/s2?
Dr. Curlee holds this position at ELCA.
What is Head of School?
Velocity is defined as what kind of quantity
What is a vector quantity?
A truck has negative acceleration as it does this.
What is slow down?
An object that falls to the ground from rest has this initial velocity?
What is zero (0 m/s)?
Since an archer shoots an arrow straight up into the sky with an initial speed of 23m/s, its speed will be this just before it hits the ground?
What is 23 m/s?
29 m/sec is a rough estimation of this highway speed?
What is 60 mph?
What is the name of the little triangle used in our formulas that denotes change?
What is DELTA?
These are the units for acceleration.
What is m/sec2 ?
This is why, on Earth, a piece of paper and a bowling ball fall to the ground at different accelerations.
What is air resistance?
An objects velocity increases by this much every second when an object is in freefall
What is 9.8m/s?
James Oglethorpe founded this colony in 1720?
What is Georgia
