Questions on motion in one dimension that are designed to facilitate knowledge construction through case-based reasoning:
1. A car is moving in a straight line with a constant velocity of 20 m/s. How far will it travel in 5 seconds?
2. A ball is thrown upward with an initial velocity of 30 m/s. How long will it take to reach its maximum height? What is the maximum height that it will reach?
3. A train is traveling with a constant acceleration of 2 m/s^2. If it starts from rest, how long will it take to reach a velocity of 60 m/s? How far will it travel during that time?
4. A roller coaster starts at the top of a hill with an initial velocity of 0 m/s. It then travels down the hill with a constant acceleration of 5 m/s^2. How fast will it be traveling after 10 seconds? How far will it have traveled during that time?
5. A person is walking at a constant speed of 1.5 m/s. How long will it take for them to travel a distance of 500 meters?
6. A student throws a ball vertically upwards with an initial velocity of 20 m/s. How high does the ball go and how long does it take to reach its maximum height? What is the ball's velocity and acceleration at its maximum height?
7. A car is driving down a straight road at a constant speed of 60 km/hr. Suddenly, the driver applies the brakes and the car comes to a stop in 5 seconds. What is the car's acceleration during this time? How far does the car travel before coming to a stop?
8. A cyclist is riding down a hill with an initial velocity of 10 m/s. The cyclist then applies the brakes and comes to a stop after traveling 100 meters. What is the cyclist's acceleration during this time? How long does it take for the cyclist to come to a stop?
9. A ball is thrown off a building with an initial velocity of 30 m/s. If the building is 50 meters tall, how long does it take for the ball to hit the ground? What is the ball's velocity just before it hits the ground?
10. A rocket is launched vertically upwards from the ground with an initial velocity of 500 m/s. If the rocket's engine shuts off after 10 seconds, how high does the rocket go? What is the rocket's velocity and acceleration at its maximum height? How long does it take for the rocket to fall back to the ground?
For each of these questions, students can use the given information to construct a mental model of the situation, and then apply the relevant physics principles to arrive at a solution. By working through these case-based problems, students will develop a deeper understanding of the concepts of motion in one dimension, and will be better equipped to apply those concepts to new situations in the future.
