OUTCOME
By the end of the lesson you will review the use of constant acceleration formulas for a falling object and use excel to model it. By the end of the lesson you will be able to apply the constant acceleration and motion formulas to solve projectile motion problems
Engage
Objects dropped fall under constant acceleration.
A projectile acts under gravity as soon as it leaves the projection system. In many cases air resistance can be considered as negligible enabling us to model the path of the projectile a as parabola.
LEARNING TASKS
Explain
Explore and Elaborate
Considering the stunt in the video, what variables would need to be measured or known to calculate the landing point to this precision. Do you think this is possible?
How does using an angled projection help the flight of the person?
The helicopter in the last problem is now not hovering at 100m but moving forward at 20 m/s.
a) How long does it take the package to reach the ground this time?
Why does the distance between each drop increase as they travel further?
A helicopter hovers 100m above the ground and drops a package.
a) Calculate how long it takes to hit the ground
b) Determine the position of the package at each second
2D model of projectile motion and then use it to place a cup in the correct position to catch a ball bearing. There will be prizes!!
