Which of the following correctly defines acceleration?
Which of the following correctly defines acceleration?
- The rate at which an object changes its position
- The distance traveled divided by the time taken
- The speed of an object at a particular instant
- A change in speed or direction in a given time (correct)
Which equation can be used to calculate acceleration?
Which equation can be used to calculate acceleration?
- $v = s / t$
- $a = v - u / t$ (correct)
- $v = u + a t$
- $a = s / t$
What is the difference between speed and velocity?
What is the difference between speed and velocity?
- Speed is the rate at which an object changes its position while velocity is the distance traveled divided by the time taken
- Speed and velocity are the same thing
- Speed is the distance traveled divided by the time taken while velocity is the rate at which an object changes its position
- Speed is a scalar quantity while velocity is a vector quantity (correct)
