How can the Equations of Motion be used to calculate missing parameters?

[staceyw]

Can someone please explain what you are supposed to do when you are only give two or three of the things (eg displacement or time) when you need four, how are you supposed to work it out then? it seems to be very confusing!
I am really confused and need help! Thanks

I would suggest making a system with two different equations.

I would like to clarify that the Equations of Motion are a set of mathematical equations that describe the motion of objects. These equations are used to calculate various parameters such as displacement, velocity, acceleration, and time. They are based on the laws of motion proposed by Sir Isaac Newton.

In order to use the Equations of Motion, you need to have at least three of the four parameters mentioned above. This means that if you are given two or three parameters, you can use the equations to calculate the missing parameter.

For example, let's say you are given the displacement and time of an object, but you need to calculate its velocity. You can use the equation v = d/t, where v is velocity, d is displacement, and t is time. By plugging in the given values, you can solve for the missing parameter, in this case, velocity.

If you are given only two parameters, then you will not be able to calculate the missing ones using the Equations of Motion. In such cases, you will need to gather more information or use other equations and principles to solve the problem.

I understand that the Equations of Motion can be confusing, but with practice and a good grasp of the underlying principles, you will be able to use them effectively. If you need further assistance, I suggest seeking help from a teacher or a tutor who can guide you through the process. I hope this helps clarify your confusion.
