Motion Project

An object in motion will maintain its state of motion unless influenced by an external force. Displacement and motion are intertwined, as an object is considered in motion if it alters its position within a specified plane.

Motion Project

If an object is in motion it will continue in motion unless a force is acted upon it

How can we predict the movement of a one Dimensional object

Why do to objects dropped at the same time and height hit the ground at the same time

They might have little air resistance and gravity is pulling down on them
We had to pennies one on the desk and the other one on a ruler. We knock both pennies of at the same time to see which one would hit the ground first. The one falling straight down was a little kicker but not by much.

In wrestling when you do a double leg takedown you both hit the mat and the same time or pretty close to the same time

What is the relationship between acceleration and velocity

They are both related to speed and when one changes so does the other
When you have a change in velocity you have a change in direction.

When you drive down the road and a deer jumps out in front you swerve. When you swerve you slow down

What is the relationship between displacement and motion

An object is in motion if it changes position in a certain plane
You are moving past a tree It looks like the tree is moving past you but it isn't you are moving past the tree

When driving down the road and you pass a semi it looks like the semi is still but it isn't
