Proficiency 2

Problem: Does the type of ball texture between a rubber bouncy ball, or a golf ball?
Hypothesis: I think that the golf ball will go farther because it is harder and will travel easier than the rubber bouncy ball that will stick to the ground and prevent it from going farther.

Proficiency 1

I will meet this proficiency by explaing and experimenting how Newtons Laws Of Motion apply to the physical world.

Speed/ Acceleration Notes

Speed And Acceleration Notes

Speed Equations
Distance
Speed Time
If the problem asks how fast
Distance divided by time= speed

If the problem asks how far.
Speed times time = Distance

If the problem asks how long
Distance divided by speed= time

Acceleration Equations
Acceleration= Final Velocity- Initial Velocity Divided by time
4mph- 13mph= -3 mph/s
