Show hintHide hint
Think about how far you traveled and how long it took you.
Question 2.
Define velocity in your own words.
Show hintHide hint
Recall that direction is important for this quantity.
3Question 3.
What is speed?
- A vector quantity
- A scalar quantity
- Both A and B

4Question 4.
The formula for velocity is:
Show hintHide hint
Remember the distinction between distance and displacement.
Question 5.
A car accelerates uniformly from rest to 25 m/s in 10 seconds. What is the distance traveled during this time?
Show hintHide hint
You need to find the acceleration first.
Question 6.
An object is thrown vertically upwards with a speed of 20 m/s. How high will it go before it starts falling back down? (Assume acceleration due to gravity is -9.81 m/s²)
Show hintHide hint
Think about when the object reaches its peak, as velocity becomes zero.
