Warm-up: Position, Velocity, Acceleration
Before doing anything strenuous, it’s important to warm up. The first section of each lab will help prepare you for the exercises to come (this section is NOT graded).
Kinematics: Warm-up
1. An object is held above the ground and dropped. It starts with a velocity m/s and in free–fall, meaning it has a constant acceleration due to gravity of in the downwards direction.
What is its velocity after 1 s, 4 s?
Write down the equation for velocity as a function of time and acceleration:
2. An object begins at m with a constant velocity m/s.
What is the object’s displacement after 1 s, 6 s?
Write down the equation for displacement as a function of time and velocity:
3. An object begins at m with a velocity m/s and has a constant acceleration. You observe the object’s movement for 4 seconds.
Will the object cover more distance between t = 0 s and t = 2 s or in the interval from t = 2 s and t = 4 s. Why?
Before moving on!
Make sure you wrote down the equations and understand all concepts discussed in the warm-up! They will be useful in the exercises to come.
