the speed at which a variable changes over a specific period of time
yes
impulse = change in momentum so, no
Change Is the Only Constant was created in 2003.
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
yes
It means something that doesn't change, like a number.
The change in y over the change in x
No
yes
Invariably means constant and not prone to change, and can mean always.
Constant just means that the number does not change. For example, in Chemistry, avogadro's number is 6.022x10^23 and that number will never change, therefore it is a constant.
Nothing stays the same for ever.
if a number can change randomly it is called a variable
The variable will change at a constant rate. Its pattern will never be broken or changed throughout its process.
the object's speed doesn't change
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
