Question 1.
Define acceleration in your own words.
Show hintHide hint
Think about how speed can change.
Question 2.
What is the SI unit for acceleration?
Show hintHide hint
Consider how we measure speed.
3Question 3.
What is the formula to calculate acceleration?
- Acceleration = (Final velocity + Initial velocity) / Time
- Acceleration = (Final velocity - Initial velocity) / Time
- Acceleration = (Initial velocity * Time) / Final velocity
Show hintHide hint
Remember how we derived the formula in class.
4Question 4.
True or False: Negative acceleration can only occur when moving backwards.
- True
- False
Show hintHide hint
Think about how objects behave when they slow down.
Question 5.
A cyclist starts from rest and accelerates uniformly at 2 m/s². How long will it take to reach a speed of 22 m/s, and how far will the cyclist travel in that time?
Show hintHide hint
Use both the acceleration formula and the distance formula.
Question 6.
A car moving at 30 m/s applies the brakes and decelerates at 5 m/s². How long will it take to stop, and what distance will it cover?
Show hintHide hint
Think about using negative acceleration for both calculations.
