What I've Learned



During physics this week, I have learned many new things when it came to free- fall. I learned that the accerleration on the earth is 9.81cm/s/s. I also learned that the weight of an object doesn't normaly affect the rate at which it falls. For example in the lab we did this week, we dropped a 200g and a 500g weight starting from the desk. Although it looked like the 500g weight fell faster, it was only due to air resistance.

I also learned that the slope of a velocity and time graph represents acceraltion. For example, in the lab it showed that slope of the average velocity and time graph represented the acceraltion.

Also I learned that in order to solve kinematic equations, you need three of the five variables to solve an equation. There is also a number of kinematic equations that we use in order to find out the variables. The variables inculde, inital velocity, final velocity, distance, accerleration, and time. Using all the equations you can solve for different variables.

Overall this week, I expanded my physics knowledge.
