– Crate– Original position – 0– Graph Acceleration (and Force)– No Friction– Applied Forces
Push the crate with any force so it starts to move to the other end…. Use your playback and pause button to find your HIGHEST force and acceleration it took to hit that force… type that data into the next slide.
Force= 620 NMass= Crate(300kg)Acceleration= A=F/M=2.1Graphed Acceleration= 2.1
YAY!!!!!
Measure at peaks!!!!
!!!
Playback
Is the ratio of the force to the acceleration constant? If so, what does this tell you about the relationship between Force and Acceleration?
Object Mass of Object (kg)
Applied Force(Newtons)
Playback and stop when moving line gets to force peak
Calculated acceleration
A=Force/Mass
Graphed Acceleration: Playback and stop when moving line gets to acceleration peak

• Add Friction, check the controls, and set the value to 0.2 for static and kinetic friction,
Does friction help motion or oppose motion (acceleration)?
Object Mass of Object (kg)
Applied Force(Newtons)
Playback and stop when moving line gets to force peak
Friction Force
(N)
Calculated acceleration
A= F/M

Conclusion
• 1. How did mass of objects effect which objects hit the ground first on Earth?
2. How did the size of the planet effect how much acceleration the objects had?
3. Which planet had the greatest effect on objects
