increasing wasn't it?
 
  • #4
Uhh... :rolleyes:

I don't remember. :confused:

Why would it be increasing?
 
  • #5
because there's acceleration.
 
  • #6
Aaaaah, yes. :)

Well, this time it's about a force.
Do you know the relation between acceleration and force?
 
  • #7
force equals mass times acceleration
 
  • #8
Good! :smile:

So we have an object moving to the right.
In which direction is the force/acceleration?
 
  • #9
the right
 
  • #10
Yep! :wink:

Do you also know the relation between acceleration and speed?
 
  • #11
acceleration is the change in speed?
 
  • #12
Yes. To be exact: acceleration is the change in speed per unit of time.

Soooooo?
 
  • #13
sooo. its increasing?
 
  • #14
Maybe...
Why would it be increasing?
 
  • #15
um because its accelerating?
 
  • #16
Yes, yes.
I think I've dragged this out long enough.
Yes, accelerating means speeding up.

What is the reason you're still doubting your own answer?

i don't know. cause i tend to be wrong. haha

What is a word problem involving a moving object?

A word problem involving a moving object is a mathematical scenario that describes the movement of an object in a given amount of time. It typically involves variables such as distance, time, and speed, and requires the use of equations to solve.

How do I solve a word problem involving a moving object?

To solve a word problem involving a moving object, you will first need to identify the variables given in the problem, such as distance, time, and speed. Then, use the appropriate equation (such as distance = speed x time) to calculate the missing variable. Finally, check your answer to ensure it makes sense in the context of the problem.

What are some common equations used in word problems involving moving objects?

Some common equations used in word problems involving moving objects include distance = speed x time, speed = distance / time, and time = distance / speed. It is important to understand the relationships between these variables in order to solve the problem accurately.

How can I check my answer for a word problem involving a moving object?

To check your answer for a word problem involving a moving object, you can use the given information and the calculated value to see if they align. For example, if the problem states that an object traveled 10 meters in 2 seconds at a speed of 5 meters per second, your calculated value for distance should be 10 meters when using the equation distance = speed x time.

What should I do if I am stuck on a word problem involving a moving object?

If you are stuck on a word problem involving a moving object, try re-reading the problem and identifying the given information and what variable you are trying to solve for. You can also try drawing a diagram or using a table to organize the information. If you are still stuck, consider seeking help from a teacher, tutor, or classmate.
