Hey y'all, I'm back with another post! This week, we'll be talking about acceleration. Acceleration is defined as the change in velocity divided by the time it takes for the change to happen. And I don't know about you, but when I think of acceleration, I think of speeding up, but there are other way to accelerate. One, of course, is speeding up. When you speed up, the acceleration is in the direction the object is going. For example, if you are riding a bicycle, gaining speed. The next way is slowing down. Yes, slowing down. You may not believe me; when you imagine acceleration, you think of a speeding car or something of the sort, but I speak the truth. When you slow down, the acceleration is in the opposite direction of where you're going. So, think of when you press the brakes on your bike. Lastly is if you change direction. When your direction changes. you velocity changes, but you acceleration stays normal. Think of when you turn a corner on your bike. Acceleration is calculated by using the formula acceleration is equal to the final speed of the object minus its initial speed, divided by the time it took. So, if you are at the top of a hill on your bike your initial speed is 0 m/s. If you ride down the hill at 20 m/s and it takes you 10 s to go down the hill, 20 m/s is your final speed, and 10 s is your time. After you divide 20 m/s by 10 s, you get 2 m/s/s as your answer.
Next comes positive and negative acceleration. Positive acceleration is just what you think is is; when you speed up. Negative acceleration is when you decelerate, or slow down. Lastly comes how acceleration is graphed. When the line rises, that means the acceleration is increasing. When it falls, that means the acceleration is decreasing. When it remains constant, that means you are moving at a constant speed.
Well, that's it for this week! I hope this was helpful
for anyone who needed it!
