Quiz 2D Kinematics (beginner)

1. A teacher brings four objects into their classroom, and asks their students to perform a thought experiment. In the thought experiment, the students are asked to imagine that the four objects are thrown in a place where the air resistance is negligible, and to consider that all objects are thrown under the same initial conditions. The question the teacher asks is, "Which object, or objects, will have the greatest horizontal range?"

 

2. Consider the following graphs. Which best represents the behavior of the velocity on the y-axis and the velocity on the x-axis in a parabolic motion?

3. Two identically shaped projectiles are launched under the same initial conditions, but in two different places, the first (blue) on the earth and the second (red) on a planet where the gravity is half that of the earth. The projectiles are launched from the ground. What can be said about their motion?
