For the one dimensional motion of an object along an axis, choose all the statements that are True.
1.) If the object reverses direction and goes the opposite way, the sign of the velocity changes.
2.) If the acceleration has the opposite sign than the velocity (and is not zero) the object slows down.
3.) If the instantaneous velocity is zero, the acceleration is also zero.
4.) An object with larger acceleration always has a larger velocity.
5.) Negative acceleration means the moving object slows down
