Space pod
Why didn't the pod accelerate after it started moving away from the space station?
There was no friction to change it's velocity.
Which mark on your spring launcher produced the greatest force?
Mark 3
What are the units of measurement for speed?
meters per second
How can you tell from a diagram which force is stronger on two different objects?
The force with a longer tail is stronger.
0
Briefly explain how the space pod was supposed to dock?
The thrusters were supposed to push against the motion of the pod and slow it down so it could dock.
Which lid reach the end of the meter stick first, the one fired from the two mark or the three mark?
Three mark
What is 1 newton equal to?
Accelerating a 1 kilogram mass at a rate of 1 meter per second squared.
The strength of the force (magnitude) and the direction of the force.
This is the sum of all forces acting on an object.
Net force
Which force is almost nonexistent in space?
friction
Give a possible explanation of why some groups had the jar lid reaching one meter at the 2 force mark instead of the third force mark.
How the spring launcher connected with the lid, user error, differences between the distance from spring launcher to the lid
What are two alternative ways we can write 1 joule.
1 newton x 1 meter and 1 kilogram times 1 meter per second squared.
Give an example of cause and effect in the force simulation.
A larger force (cause) created a greater change in speed. (effect)
In order for an object to speed up, the force applied should be in the __________ direction.
same
What are two possible explanations of what happened to the pod when it lost connection with the space station.
The pod might not have slowed down enough and bounced off the space station, or the thrusters fired to much and the shuttle started moving the opposite direction.
Describe how doing the lid and spring launcher experiment in space would be different from the results of doing it on Earth.
The lid would not speed up or slow down in space because there is no friction in space.
What is a joule of work equivalent to?
Exerting a force of exactly 1 newton over a 1 meter distance.
Explain how you caused your masses to slow down enough to fall into the hole on the simulation.
You exerted a force directly opposite of the motion of the mass.
In order for the object to slow down the force should be in the _________ direction.
opposite
What are five ways that the velocity of the space pod can change?
speed up, slow down, come to a stop, change direction, start from rest
A jar lid takes 2.5 seconds to m ove past the meter mark. What is its speed?
.4 meters per second
What is the equation to find power?
work divided by time.
What are two things you could do during the "Run mode" of the simulation.
exert forces on objects in real time, pause the sim to set up forces using prepare force, observe the direction and relative strengthof forces exerted on the object, turn velocity visuals on or off, turn force visuals on or off.
What is the independent and dependent variable in the spring launcher and lid experiment.
independent variable is the force of the spring launcher and dependent variable is the effect of the spring launcher on the lid.
