Vad är likformig hastighet?
98-103) Ett föremål rör sig likformigt om både hastigheten och färdriktningen är konstant (oförändrad). Ett föremål rör sig likformigt med hastigheten 5 m/s.
Vad är koefficient matte?
En koefficient är ett tal som står framför en variabel eller en funktion. Nedan visas ett algebraiskt uttryck där variabeltermerna har koefficienterna 2 och -8. Koefficienten kan tolkas som ”hur många” av en viss term det finns i uttrycket, vilket här är 2 st. x3-termer och -8 st.
What does it mean to have constant acceleration?
Constant acceleration means that the acceleration does not change. Some would say that if the acceleration is zero then the acceleration does not change and so one can say that the acceleration is constant. What others would say is that if there is no acceleration it is meaningless to qualify what type of acceleration it is as it does not exist.
Can acceleration be zero and still have constant velocity?
If your acceleration is 0, and stays 0, then yes, its a constant acceleration, and you have to understand this also means constant velocity. But Mr. Common Sense says, hey, it’s just easier to label this as NO acceleration and constant velocity.
How do you know if something is accelerating?
In the real world deffinition something is accelerating if its speed is changing, if its not then there is no acceleration. The argument that you are actually acclerating with a constant zero function just seems like an overcomplication of the obvious fact that you aren’t acceleration to most people.
Is an acceleration of 0 the same as a cosmological acceleration?
In the scientific deffinition then clearly an acceleration of 0 is a cosntant acceleration. In the real world deffinition something is accelerating if its speed is changing, if its not then there is no acceleration.
