Hi... well anyways so I am in 7th grade but I'm taking 8th grade science...I think...I know for sure that I am in Accelerated 7th grade science so if that helps at all, there you go:)
Back to the subject I'm really confused with acceleration calculation and velocity, time, speed, distance, etc.
I have a quiz on it tommorow and a test on thursday, so if anyone could help that would be fantastic! Oh and I also have this really hard worksheet that is getting graded and I certinly will FAILLLLL! :(
You have not asked a question. That is probabkly why no one has responded thus far. If you wish, send us a few specific questions from your worksheet that are giving you trouble.
Velocity is the rate of change of location and accleration is the rate of change of velocity.
Time is what it is.
i'll try my best to explain them as simple as possible.
(i) distance - how far an object has moved. it is in units of length (meters, kilometers, etc)
(ii) speed - distance traveled over certain time, or in formula,
v = d/t
where
v = speed
d = distance
t = time
it has units of length/time. for example m/s, km/h, etc.
(iii) velocity - displacement over time. it is almost the same with speed except that speed is scalar (or does NOT indicate the direction), while velocity is vector (or it indicates the direction).
(iv) acceleration - change in velocity over time, or in formula,
a = (v2 - v1)/t
where
a = acceleration
v2 = final velocity
v1 = initial velocity
t = time elapsed
it has the units of length/time^2. for example, m/s^2.note that if in the problem it is stated that the velocity is constant, acceleration is zero.
note that the formula to use to calculate these quantities still depend on the problem. some of the formulas here are for objects in 'Uniform Motion' (a = 0, thus v = constant) and can not be used for objects in 'Uniformly Accelerated Motion' (a = constant and not equal to 0)
hope this helps~ :)
Place the following words into the illustration below: gametes, sporophyte, gametophyte, and zygote. Explain how the terms are related.

To a blank labeled 2., (egg and sperm) underneath the blank; next arrow points from 2. to blank labeled 3, next arrow points from 3. to blank labeled 4. (5 points)

It's basically gym
Hi there! I'd be happy to help you understand acceleration calculation and the related concepts like velocity, time, speed, and distance. Let's break it down step by step so you can grasp the concepts and do well on your quiz, test, and worksheet!
First, let's start with some definitions:
- Velocity refers to the speed and direction of an object's motion. It is a vector quantity, meaning it has both magnitude (speed) and direction.
- Speed, on the other hand, is a scalar quantity and represents only the magnitude of an object's motion.
- Distance is the total length traveled by an object, and it is also a scalar quantity.
- Time measures the duration of an event or how long something takes.
Now, let's focus on acceleration:
- Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity.
- Positive acceleration means the velocity is increasing, while negative acceleration (or deceleration) means the velocity is decreasing.
To calculate acceleration, you can use the following formula:
a = (Vf - Vi) / t
Where:
a is the acceleration
Vf is the final velocity
Vi is the initial velocity
t is the time taken
If you know any three of these variables, you can solve for the fourth. Keep in mind that this equation assumes constant acceleration.
Regarding your worksheet, if you have specific questions or calculations you're struggling with, please let me know, and I'll guide you through them! It's always helpful to provide specific examples so I can assist you more effectively.
Don't worry; with some practice and understanding, you'll improve your understanding of these concepts and do well on your assessments!
