When landed box hit the ground and the ground hit the box
Which of Newton’s laws states that an object tends to continue in the same path unless acted on by another force?
First law
If I have a 200 kg object traveling at 25 meters per second what would have more of an effect on the total joules?
adding mass or velocity?
Velocity
What would be the effect of the total potential energy be if an item were to be dropped on the moon where there is less gravity and why
The total energy would be less becasue ther is less gravity
An object has a kinetic energy of 25 J and a mass of 34 kg , how fast is the object moving?
1.21 m/s
At what point in the egg drop did your device show Newton’s second law of motion and how did it show this?
When the box hit the ground it had a lot of force becasue the boxed accelerted to a stop quickly

2.44 kgs
At what point in your egg drop did it show Newton’s first law of motion and explain how does it show it?
When you dropped the box it was not in motion until an outside force, gravity pulled the box down.
What is the term for the tendency of a moving object to want to keep moving?
Inertia
What would have more of an effect on the GPE, if I added more mass or more height?
Both have the same effect.
