How can we predict the movement of an object in one dimension
Q1 What is the relationship between displacement and motion?
-
Displacement is the length of a straight line from an object's initial position to its final position.
Displacement is not the same as distances. Distances is how far you have gone. Displacement is the distance between your initial point and your final position.
Motion is the action or process of moving or being moved.
Connections
Vocab- Initial Reference - The starting point of an object that has experienced motion.
Claim- The relationship between displacement and motion is displacement is used to calculate motion.
Q2 What is the relationship between velocity and acceleration?
Velocity- speed in a given direction
Acceleration- when there is a change in velocity/ ΔV
Acceleration occurs when there's: An increase in speed, A decrease in speed, or a change in direction
Claim- Velocity and acceleration are both related to speed. They are also each other, the only
Q3 Why do two objects released at the same time and height hit the ground at the same time?
Claim- Objects undergo constant acceleration. without air resistance all objects near the surface of a planet will fall with the same constant acceleration
The constant free fall acceleration is due to gravity
When you shoot a bullet level and drop a bullet at the same height they will hit the ground at the same time.
