PhET Simulation: Projectile Motion
– You will use a computer simulation today to reinforce your ideas of
vectors, acceleration and velocity.
You will also start to investigate what projectile
Since this is “inquiry based”, you’re not supposed to know everything going
in, but learn as we walk through the lesson.
Projectile Motion refers to the motion of an
object that is shot through the air.
Think an arrow shot from a crossbow or a cannonball
shot from a cannon.
This motion depends on many factors including gravity, air
resistance, altitude, mass, initial speed, etc.
In this simulation, we will be examining
Part I: Intro
Begin with the cannon as is:
Pumpkin, 15 m/s initial v, 0 degree loft.
Shoot the pumpkin
Next shoot the pumpkin at initial speed of 25 m/s.
Finally fire the pumpkin at the
initial speed of 0 m/s.
Use the crosshairs marked with time range and height to mark the
last dot of the flight.
Fill in the table below with the values. Extend the table and use 2
more values for the initial velocity (your choice)
