What is Acceleration?
Motion determined solely by gravity
What is free fall?
The unit used to measure distance
What is a Meter?
The rate of motion is referred to as ____
What is speed?
An object propelled through the air.
What is a projectile?
These 2 things cause velocity to change
What is the speed of an object and the direction of motion?
For an object tossed into the air, the acceleration is the same on the way up and on the way down. True or False?
True
The letter used to label position
What is the letter X?
Average speed is always negative. True or False?
False, average speed is always POSITIVE
a bullet, a ball, a missile, an elephant and a toaster are all projectiles. True or false?
True, anything can be a projectile if you're determined enough.

Who is Galileo?
When an object is in motion, it's position is changing. True or False?
True
What is the formula for average speed?
Average Speed=distance/elapsed time
What is projectile motion?
A form of motion where the object moves in a parabola.

What is the speed of sound in air?
343 M/S
"Horizontal motion is a factor of velocity, objects moving and they going pretty constantly. None of those forces acting on the object. Could it go forever? Well we thinking maybe possibly."
