  1. My last topic was too complex for me so I decided to change it to something simpler but I'm having hard time developing my ideas. I'm planning to do my math IA on something about projectile motion and baseball using calculus. My current idea is "what is the most ideal angle for a batter to hit a home run with the least force possible?". I know that I will take air resistance into account, but I may neglect drag force caused by wind as the calculations may be too complex. Also, I'm not sure if I should include the calculation for momentum of ball-bat collision or not as it may be too physics-li
  2. I have my Physics exam tomorrow and I have a few questions in various chapters. Measurements and uncertainties: If in a calculation, I find the answer to be 500, but the numbers that I used all have 3 significant figures, would I be able to give the answer as 500? Does that have 3 significant figures? Or would the answer be 5 x 102 ? When finding the absolute uncertainty with the percentage or maximum/minimum method, what are some rules that apply here? In my notes I wrote down that if there is addition or subtraction in the original equation, then I must add the absolute uncert
  3. What's the difference between the Normal Force and Newton's Third Law of Motion? Because they sound pretty similar.
  4. I'm in Grade 10 and I have to come up with a simple physics experiment on kinematics experiment for an investigation, we're not allowed to do free falling or how the angle of a ramp affects speed or acceleration. I'm completely stuck so I was wondering if any of you had any ideas, preferably one using SUVAT equations. thank you
  5. In this video squirtle is falling in free fall up to second 12, when he starts using hydro-pump and propels itself up. If I want to calculate the kinematics for this, do I assume he is going up from a still position? Or in which ways can I found out what velocity that would be? Also, when at 0:15 he reaches a maximum point and remains in equilibrium for certain time, the only way for this to happen is if he stops accelerating and all forces balance out, but if he suddenly reduced the intensity of his hydro-pump at the maximum point, he would keep momentum and go up a little bit still, thus
  6. I'm studying for my math test and there's this one question I'm just not getting. A particle moves along a horizontal line with velocity given by v(t) = 2t^2 - 11t +12 where t is greater than or equal to zero. Find the total distance the particle travels from time 2 seconds to time 5 seconds. The question also asks to find acceleration and "a" and "b" if the particle is moving left for a<t<b. Both of which I have figured out. It's just the total distance I can't figure out. We've done other problems in class and I figured them out. My teacher said just to graph it and write out a
