At the beginning of class on Lab 4, we will have the first assessment. It should take less than 1 hour. Here are the topics that will be included.

Vectors

The momentum principle in 1-dimension

The basics of numerical calculations

The basics of measurement and uncertainty

Motion of an object with constant acceleration

Interpret and use graphs for motion in 1-D.

Here are some sample questions:

1. Vectors – look at the practice sheet posted in blackboard.

2. Write a sample part of a python code so that a it will create a ball located at position <5, -4, 6> m with a radius of 3 meters.

3. Make another ball at position <6, 2, -7> m with a radius of 2 meters.

4. Create a yellow arrow that points from the ball in question 2 to the ball in question 3.

5. Here is a graph of position-time for a cart with a fan on it.

Is the force on this cart constant or not? How do you know? How would you convince a friend that you are correct?

6. An object is dropped from rest at a height of 1.33 meters. How long will it take to hit the ground? What is the speed when it hits the ground?

7. If I give you position-time data, you should be able to plot it on graph paper and by using a best-fit line find the acceleration.

8. Suppose you launch a cart towards a force detector with a spring. The cart has a mass of 330 grams with an initial speed of 1.2 m/s to the left. After contact with the spring, the cart is moving with a speed of 0.8 m/s to the right. If you were to find the area under the force-time graph, what would you expect to find for this situation?
