Projectile motion questions are an interesting phenomenon in your MCAT Physics preparations. Think back to your general physics course, if you had to solve a projectile motions question you likely found yourself spending 20-30 minutes on a question complete with 3-4 unique calculations.
However, you won't have the leisure of time on your MCAT. And so the video below shows you how to focus your study time where projectiles are concerned, in addition to walking you through a multi-step practice problem with a focus on how to think ‘MCAT Style' each step of the way.

You can use the quadratic if you set delta Y to 0, understanding that the height of the projectile is 0 initially and 0 when it hits the ground, assuming that the plane is level.
Do you have a video for motion on an inclined plane?

How come for the equation you are using to find t, the vi part you used viy part (25) instead of the vx value? I’m a little confused about that.
Why do you use Viy in the Vf=Vi-gt equation, rather than Vi? (25 rather than 42.1)?
Love these videos, thank you!
how does the 8 * 0.2 apply?
Just wondering, why is the distance different from the base of the triangle? So in this instance, we solved for the base of the triangle, which was ~34m. Why would this not be the distance?

This was extremely helpful! Helped me understand how to look at projectile motion questions and actually understand what I’m doing.Thank you very much!
Great! I love to hear that, Maria! You’re very welcome!
how to compute for a problem with air resistance? thank you
Your videos are the most helpful I’ve found yet!
Thank you Naimah
Concerning projectile motion, do you always take gravity to be negative, regardless of which direction the object is moving (up or down)?
Also what is the sign for ‘y’ in that case, does that change too?
Gravity is acceleration in the negative Y direction regardless of the direction of velocity
these videos are great! thank you!
Thank you. Which topics are you currently working on?
